no exception it will give you coenzyme a

play00:36

and coenzyme a sh the famous co ashe

play00:40

vitamin b5 it's a water-soluble vitamin

play00:44

therefore toxicity is very unlikely why

play00:47

because any excessive amount will be

play00:48

excreted by your kidney deficiency is

play00:51

more likely theoretically but actually

play00:53

with pantothenic acid deficiency is

play00:55

extremely rare so deficiency is rare

play00:58

toxicity Israel that's amazing B complex

play01:02

b1 is time in b2 is riboflavin and b3 is

play01:05

nice and we have talked about them in

play01:07

previous videos in my playlist called

play01:09

biochemistry honestly I wanted to make a

play01:12

video about vitamin before but vitamin

play01:14

before does not exist

play01:16

so after serious thought and

play01:18

contemplation have made the hard

play01:20

decision which is to talk about vitamin

play01:22

b5 today pantothenic acid let me tell

play01:25

you about something that drives me nuts

play01:27

I went to the store to get some vitamins

play01:29

ok and look at this

play01:31

where is pantothenic acid pantothenic

play01:33

acid is right here where is vitamin b1

play01:37

vitamin b1 is thiamine and it's right

play01:40

here but this is really really ugly i

play01:43

know i'll tell you why because thiamine

play01:45

is b1 so instead of writing fireman and

play01:47

pantothenic acid why don't you a bunch

play01:50

of doofuses do it like this vitamin A

play01:52

first is number one who starts with 2

play01:54

carbohydrate on a bottle of vitamin who

play01:56

goes to the store oh I'm actually

play01:58

worried about my carbohydrate intake let

play02:00

me go get some vitamins oh shut up

play02:02

started alphabetically baby so vitamin A

play02:05

is number one and then you go with

play02:06

vitamin b1 which is thiamine vitamin b2

play02:09

which is riboflavin b3 which is nice and

play02:12

beef

play02:13

or doesn't exist b5 which is pantothenic

play02:15

acid and then basics which is pyridoxine

play02:18

b7 is freaking biotin b9 is folate but

play02:22

to be honest you should write it as

play02:24

folic acid because folate is natural

play02:26

folic acid is artificial know that I

play02:28

care but it's just a tiny bit and ABC

play02:32

vitamin C and then you go with D which

play02:34

is act the form so it's gonna be d3 mr.

play02:36

Kelsey try yo like this look at the

play02:39

beauty and you become organized like a

play02:41

normal human being not like this garbage

play02:44

I really don't know who is to blame is

play02:46

this like a government regulation that

play02:48

regulates you have to do it like this or

play02:50

is it the fact that the formas is to

play02:52

actually make the freakin drug is

play02:54

different than the marketing team who

play02:56

designed this freaking thing someone

play02:59

needs to get their act together man I'm

play03:01

a little OCD so please forgive me okay

play03:03

when you go to the store and you get

play03:05

some bread okay let's do it nice and

play03:07

that's b3 Simon that's me one riboflavin

play03:10

that's b2 folic acid that's b9 whereas

play03:13

pantothenic acid oh it's not there

play03:16

hey Walmart I need my money back Oh calm

play03:20

down calm down before some safety

play03:22

Crusaders raid the store lemme explain

play03:25

pantothenic the word literally means

play03:28

from everywhere he can find vitamin b5

play03:31

literally in every food so even a former

play03:35

did not fortify the bread with

play03:36

pantothenic acid you will be okay so

play03:38

chill your butt down panto means all

play03:41

that's why the word pen to mine means

play03:43

all communication you're supposed to

play03:45

communicate everything without using

play03:47

words cenek means strength that's why

play03:50

the word hypo stay Nia what does high

play03:54

Postini mean hypo means low St Nia means

play03:57

strength so low strength it's like

play04:00

thrombus tinea of platelets trumbo

play04:02

platelets asthenia is weakness because a

play04:05

means no asthenia is strength

play04:08

so pantothenic all strength which means

play04:11

from everywhere so if the exam question

play04:14

says please mention all of the food

play04:17

sources of vitamin b5 if you write any

play04:19

food that you know like anything you

play04:22

will be correct meat fish fruits

play04:24

vegetable seeds

play04:26

from everywhere baby why the flip doing

play04:29

in vitamin b5 to get coenzyme a co a and

play04:32

co enzyme a sh

play04:36

this is goings I'm a this is a thigh

play04:38

you'll grow because thio means sulfur

play04:40

artificial sources as you know enriched

play04:42

food or vitamin b-complex supplements

play04:44

like the stupid bottle that I got from

play04:46

the store a vitamin b5 deficiency is

play04:48

extremely rare vitamin b5 toxicity is

play04:51

also extremely rare thank God

play04:54

mΓ©dicos is by you tips b1 is time and

play04:57

decarboxylation baby B 2 is riboflavin

play04:59

redox reactions baby b3 reduction

play05:02

oxidation again b5 will give you

play05:03

coenzyme a what is the function of coins

play05:06

I mean lots of functions pyruvate into a

play05:08

Saluki needs Kawai whereas fight of it

play05:11

coming from it came from glucose hashtag

play05:13

glycolysis remember in glycolysis

play05:15

glucose becomes pyruvate and then

play05:17

pyruvate wants to enter the TCA cycle

play05:19

but for it to enter this choice belt has

play05:21

to become as soak wafers and you need Co

play05:24

a to be added to pyruvate so that can

play05:26

give you a Satoko a also if you want to

play05:29

destroy and break down fat in other

play05:32

words to convert the fatty acid to small

play05:35

molecules of acetyl co a you need Co a

play05:37

and if you want to build up fat fatty

play05:40

acid synthesis or fatty acid elongation

play05:42

of long chains or like short chains into

play05:45

long chains you also need Co a so

play05:47

whether you're talking about fatty acid

play05:48

synthesis or fatty acid oxidation either

play05:50

one requires Co a you can think b5 we

play05:54

love Estill Co a because it can enter

play05:56

into the TCA cycle in the mitochondria

play05:58

and give us energy vitamin b5 absorption

play06:01

is pretty straightforward you literally

play06:03

eat anything and it has vitamin b5 also

play06:07

your lovely bacterial microbiome will

play06:09

add some vitamin b5 to you absorbed boom

play06:13

you habit so bandhasana guys would it

play06:15

come from it came from beta alanine and

play06:17

and too weak acid leading to a

play06:19

pantothenic acid which is an amide

play06:21

remember the famous three enzymes that

play06:24

required 5 cofactors one of the five

play06:27

cofactors were Co ash which came from

play06:30

vitamin b5 or pantothenic remember the

play06:32

mnemonic Teflon company T is time and F

play06:34

is riboflavin F ad l as a lipoic acid n

play06:39

is

play06:39

ad from niacin or b3 co is co ash from

play06:44

b5 Panasonic baby

play06:45

what are these enzymes that need five

play06:47

cofactors pyruvate dehydrogenase

play06:49

alpha-ketoglutarate dehydrogenase

play06:50

branched-chain alpha-keto acid

play06:51

dehydrogenase let's start with pyruvate

play06:55

dehydrogenase co h carbohydrate glucose

play06:57

in glycolysis becomes pyruvate by

play06:59

pyruvate dehydrogenase becomes a slave

play07:01

we love as look why because it can

play07:04

become TCA cycle energy there is another

play07:07

reason why we love Estill Co a it can

play07:09

become fat hashtag fatty acid synthesis

play07:12

cool pyruvate dehydrogenase the five

play07:15

cofactors you can thank b5 here is just

play07:18

another simplistic version carbohydrate

play07:20

glucose pyruvate pyruvate dehydrogenase

play07:22

acetyl co a into the TCA cycle equals

play07:25

ATP whether you eat carbohydrates

play07:27

proteins or lipids they will end up as

play07:30

acetyl co a whether he ate the bun that

play07:33

she is or vomit in the burger you will

play07:37

end up as a Zuko a into the TCA cycle

play07:39

energy so we are done with the first

play07:42

enzyme which was pyruvate dehydrogenase

play07:44

to talk about the second enzyme alpha

play07:46

ketoglutarate dehydrogenase it's here

play07:48

baby and it requires five cofactors coax

play07:50

you can think b5 what is the TCA cycle s

play07:54

leuco a enters citrate to isocitrate

play07:56

alpha ketoglutarate succinylcholine 8

play08:00

femur eight malade oxaloacetate back to

play08:02

acetyl co a we are done with the first

play08:04

enzyme pyruvate dehydrogenase the second

play08:07

enzyme was alpha keto glutamate

play08:09

dehydrogenase the third enzyme is

play08:10

branched-chain alpha-keto acid

play08:12

dehydrogenase part of the proteins so we

play08:14

eat proteins they become amino acid

play08:16

let's say that the amino acid is

play08:17

loosened it requires branched-chain

play08:19

alpha-keto acid dehydrogenase to become

play08:21

a sloka atc it's like money leucine is

play08:24

an amino acid you can call this enzyme

play08:26

branched chain amino acid dehydrogenase

play08:27

or branched-chain alpha-keto acid

play08:29

dehydrogenase become whatever and then s

play08:31

okay thank you so much however bad news

play08:34

it can become a co acetic acid which is

play08:35

a ketone body can lead to high anion gap

play08:38

metabolic acidosis in high anion gap

play08:40

metabolic acidosis your pH is low your

play08:43

bicarbonate is also low but the lung is

play08:45

trying to compensate Hey we have

play08:48

acidosis here let's get rid of the acid

play08:50

that I can get rid of which is co2

play08:53

so pco2 will also be low as a

play08:56

compensation how about the anion gap

play08:59

it's called high anion gap metabolic

play09:00

acidosis so the anion gap will be low

play09:03

why do we love acetyl co a because it's

play09:06

towards the TCA cycle remember Estill Co

play09:09

a enters saturate isocitrate alpha

play09:12

ketoglutarate succinylcholine

play09:14

succinate from rate malate oxaloacetate

play09:16

back to a silicon a yep it's doozy it

play09:19

also forms a so choline so you get the

play09:22

Estill Co a from here acetyl co a plus

play09:26

choline and we'll give you the great

play09:29

acetone choline which is needed at the

play09:32

neuromuscular Junction here is the nerve

play09:34

ending here is your lovely muscle the

play09:36

nerve is talking to the muscle how does

play09:38

the nerve talk to the muscle by

play09:39

secreting a so choline thanks to calcium

play09:42

who ruptured the vesicles ahsoka we in

play09:44

here into the cleft it's binding to as

play09:47

the choline a receptor and this is

play09:50

heavier muscle contracts who is the

play09:52

enzyme that's responsible for combining

play09:54

SL co a with choline to form acetyl co a

play09:56

it's called choline acetyltransferase

play10:00

choline acetyltransferase love it and

play10:03

then the SL choline binds the receptor

play10:05

thank you we contract the muscle okay

play10:07

would you leave your muscle contraction

play10:09

no this is called the right guru mortis

play10:11

you're dead you gotta relax the muscle

play10:14

man how do you relax this muscle beat

play10:16

the living crap of the acyl co we break

play10:18

it down baby how do you break down the

play10:20

acetylcholine it's called a still

play10:23

choline esterase

play10:24

and then it will give you choline and

play10:28

acidic acid or acetate all right cool if

play10:32

you have a patient who suffers from

play10:34

myasthenia gravis so myasthenia gravis

play10:36

the acyl choline is not functioning

play10:38

because of the receptor is toast because

play10:40

of the o2 antibody we would like to

play10:42

prolong the action of a Sokoli so

play10:44

prevent its degradation by giving a

play10:47

group of medication known as the acyl

play10:50

choline is trace inhibitors such as

play10:53

neostigmine pi reduced egg mean etc what

play10:56

else has to occur a escalation reaction

play10:59

EF you need to ask you tell something

play11:00

you can call acetyl co a cholesterol

play11:03

synthesis your testes needed

play11:06

and your ovaries and your adrenals

play11:09

ketone body formation za baby when you

play11:12

don't have glucose or carbohydrate the

play11:14

next step is to make ketone buds your

play11:16

brain love ketone bodies but to be

play11:19

honest your brain loves glucose more

play11:21

elongation of fatty acid this is called

play11:23

fatty acid synthesis we're trying to

play11:26

build up fat not to break down the fat

play11:28

how do you build a fat you need a

play11:30

Sissoko a and another friend called Melo

play11:33

Nilka a and s loco a is needed to be

play11:37

converted into melon okay then the melon

play11:40

milk away together with the acetyl co a

play11:42

will combine to each other to elongate

play11:44

the fatty acid

play11:46

whenever you see Co as you can thank a

play11:48

vitamin b5 Co a coenzyme a also known as

play11:52

Co acetylase sh is the file group b6 is

play11:55

also needed let's talk about fatty acid

play11:58

synthesis because we need coenzyme a so

play12:00

we need a vitamin b5 which is

play12:02

pantothenic diet you either eat

play12:04

carbohydrate protein or fat fat contain

play12:06

triglycerides when you break them down

play12:08

Jeff goes through and free fatty acid if

play12:10

you have enough energy let's store some

play12:14

energy for a rainy day let's store the

play12:16

fatty s and how would you store the

play12:18

fatty acid would like to elongate them

play12:20

and make them big make them big

play12:22

molecules and then store them into add a

play12:24

post or into the liver whatever you want

play12:27

to store them at so first you need to

play12:29

even gave them and this process called

play12:30

fatty acid synthesis fatty acid

play12:33

synthesis let's do it we need three

play12:35

steps citrate shuttle Estill Co a

play12:37

carboxylate and fatty acid synthase

play12:39

let's start with the citrate oh you know

play12:40

that TCA cycle yeah as sue : n citrate

play12:44

isocitrate of Fekete ogler we get it so

play12:47

it has citrate cool citrate we'll take a

play12:50

shuttle from within the mitochondria to

play12:52

the cytosol outside of the mitochondria

play12:54

let's go visit Rachel number one is done

play12:57

thank you so much now citrate is free

play12:58

from the tyranny of the mighty

play13:00

mitochondria then we will break the

play13:03

citrate down hashtag citrate lyase lysis

play13:06

baby now we have a Satoko a a Satoko a

play13:10

will need to support a friend called

play13:12

melanin co a so this is step number two

play13:15

Asuka a carboxylate lets carboxylate the

play13:19

s

play13:19

we'll go into Mellon Alcoa and step

play13:21

number two is done as Lucca a

play13:23

carboxylase then the Mellon malko a will

play13:26

return the favor to his friend soql they

play13:29

will combine together they can need some

play13:32

help from vitamin b5 or Panasonic acid

play13:34

and this enzyme is called the fatty acid

play13:36

synthase complex it needs pantothenic

play13:39

baby and now we have the Palmetto Alcoa

play13:42

which is a fatty acid but it's long it

play13:45

has lots of carbons mission accomplished

play13:48

fatty acid synthesis is in the books

play13:50

whenever you see coenzyme a look at this

play13:53

citrate and news s co a here and then we

play13:56

have s local a methanol po a whenever

play13:59

you see co a you can think pantothenic

play14:02

acid om Hillary Clinton I mean I am

play14:05

insolent and I approve this message

play14:07

why would insulin approve the fatty acid

play14:10

synthesis I'll tell you why what's the

play14:11

purpose of insulin is it to build up

play14:14

stuff or to destroy stuff it's to build

play14:16

up stuff what do you mean I mean it's to

play14:18

build up proteins it's to build effect

play14:20

what do you mean by build up fat I mean

play14:23

store the fat elongate the fat

play14:25

synthesize the fat you mean like the

play14:28

opposite of break down the fat exactly

play14:31

so insulin loves for you to build up fat

play14:34

it loves fatty acid synthesis that's why

play14:37

insulin will stimulate the fatty acid

play14:40

synthesis process how about glucagon

play14:42

know glucagon is the opposite Google gon

play14:44

will inhibit the fatty acid synthesis

play14:46

let me tell you something else

play14:48

why does answering lower the glucose

play14:50

level in your blood because insulin will

play14:53

suggest that the glucose enters into the

play14:56

cell because we need to build up stuff

play14:58

in the cell not to destroy it and become

play15:01

governor no no the opposite baby will

play15:02

need to get it into the cell so that we

play15:04

can build up carbohydrate that's why

play15:07

medicine makes so much sense once you

play15:09

understand what the flip you're talking

play15:10

about same thing insulin will tell the

play15:12

cell hey you took some glucose do you

play15:14

need some fatty acids with them oh yeah

play15:16

let me alone gave them and then store

play15:19

them Thank You insulin this happens in

play15:22

the feeding state when you are full you

play15:24

have tons of energy let's save and store

play15:27

some energy for a rainy day

play15:29

hashtag feeding state but how about the

play15:32

fasting state I'm stranded in the desert

play15:34

I'm hungry I'm starving oh let's break

play15:38

down some fat which we have stored

play15:41

before for a rainy day

play15:42

and let's oxidize the fat to give you

play15:45

some energy cool man I mean how do you

play15:48

do it it's called beta oxidation so beta

play15:50

oxidation is like breaking down the fat

play15:53

into a slim ko a hashtag energy indeed

play15:56

meat actually is breaking down the fat

play15:58

so let's talk about fatty acid oxidation

play16:00

you eat fat it has triglyceride by

play16:03

hormone-sensitive lipase it becomes

play16:04

glycerol and fatty acid cholesterol has

play16:06

a pathway we don't care about it right

play16:08

now

play16:08

fatty acid have another pathway beta

play16:10

oxidation there is also alpha oxidation

play16:12

and Omega oxygen I know nerd shut up

play16:15

we're focusing on beta oxidation now

play16:17

acid SoCo is here enters in please see a

play16:19

cycle give us energy but I have bad news

play16:22

it can also become ketone bodies raising

play16:24

the anion gap and causing metabolic

play16:26

acidosis fatty acid oxidation now we are

play16:30

not trying to build up fat we're trying

play16:32

to destroy the fat break down the fat

play16:34

oxidation baby three steps again

play16:37

activation carnitine shuttle not to be

play16:39

confused with the citrate shuttle of the

play16:41

fatty acid synthesis and beta oxidation

play16:43

of even sea change wherever so here is

play16:47

the deal you eats fat triglycerides goes

play16:49

through and fatty as fatty acid will

play16:51

float in the blood but it's bound to

play16:52

albumin how would you get that fatty

play16:54

acid to become energy here is the deal

play16:57

we need three steps first activation

play16:59

let's do it fatty acid Kawai synthase

play17:02

fatty acyl Co a so fatty acyl coil

play17:05

that's brilliant that's what we mean by

play17:07

activation step one is in the books to

play17:10

carnitine shuttle let's shuttle the

play17:13

fatty acyl Co a from the cytoplasm into

play17:17

the mitochondria which is the opposite

play17:19

of fatty acid oxidation does anyone

play17:21

remember we shuttled the citrate from

play17:24

within the mitochondria to without cool

play17:27

30s Alcoa is now in the mitochondria and

play17:30

step two is now in the mitochondria step

play17:34

three beta oxidation acetyl co a ooh

play17:37

that's the purpose of beta oxidation

play17:39

which will give you energy and sometimes

play17:42

some ketones I am NOT insulin glucagon

play17:46

and I approved this message

play17:48

hashtag fasting state because when

play17:51

you're fasting you're trying to destroy

play17:53

and break down the fat into energy

play17:55

because you're starving in the Sahara

play17:58

Desert let's summarize the vitamin b5

play18:01

will give you co ACO a is necessary for

play18:03

s luke away and we have talked about the

play18:05

functions of s okay also suck smoke away

play18:07

remember this is part of the TCA cycle

play18:09

it can also help you make him and you

play18:11

mean you need him for hemoglobin in the

play18:14

red blood cells also to break down

play18:16

ketones hashtag keto lysis which is not

play18:20

to be confused with ketogenesis

play18:22

this is for a slick way so whether

play18:24

you're trying to make ketones or break

play18:26

down ketones Co a can help thank you so

play18:28

much pantothenic acid also lipid

play18:31

metabolism

play18:31

whether it's fatty acid synthesis or

play18:34

fatty acid oxidation vitamin b5

play18:37

deficiency pantothenic acid baby

play18:39

deficiency is extremely rare a

play18:42

deficiency syndrome hasn't been proven

play18:44

in humans symptoms in experimental

play18:48

animals fatigue growth and

play18:49

graying hair dermatitis which makes

play18:51

sense because this is another vitamin B

play18:54

remember vitamin b3 which was nice and

play18:56

diarrhea dermatitis dementia yep as well

play18:58

as fad ulam so does that mean that these

play19:00

symptoms are gonna be seen in humans not

play19:02

necessarily maybe maybe not for instance

play19:06

when they inject rats or mice with a

play19:09

huge amount of vitamin C some of them

play19:12

develop bladder cancer of course this is

play19:15

not true in human beings otherwise all

play19:18

of the Instagram influencers will lose

play19:20

their jobs ash tank vitamin C hashtag

play19:23

immunity hey shut up Roger Williams born

play19:27

in India became the top chemist in

play19:30

University of Texas at Austin and then

play19:32

became the president of the American

play19:34

Chemical Society who are these people

play19:36

and what do they do for a living

play19:37

he discovered vitamin b5 pantothenic

play19:39

vitamin b6 pyridoxine

play19:41

lipoic acid one of the five cofactors

play19:44

for pyruvate dehydrogenase alpha

play19:46

ketoglutarate arose branched-chain

play19:47

alpha-keto acid dehydrogenase also

play19:50

evident which avidly

play19:51

binds biotin and prevents the absorption

play19:54

causing of item

play19:55

p7 deficiency also he isolated and named

play19:58

folic acid thank you so much sir look at

play20:01

this

play20:01

this is classic male pattern alopecia a

play20:05

vitamin b5 in a nutshell so here is

play20:08

pantothenic acid literally means from

play20:10

everywhere it's found in every food and

play20:13

then coenzyme 8 if you'd like to make

play20:15

part of it in s Luke away and an energy

play20:17

I will help you fatty acid degradation

play20:20

hash tag beta oxidation of freaking

play20:23

healthy fatty acid synthesis and

play20:26

elongation I'll help you succinylcholine

play20:28

to the TCA cycle are also healthy thank

play20:32

you so much pantothenic acid question of

play20:34

the day what's the difference between

play20:35

pantothenic acid and pen to thin Nate

play20:37

let me know the answer in the comment

play20:39
