What are Carbohydrates? What are its different Types?
Summary
TLDRCarbohydrates, essential energy sources for the body, are organic compounds composed of carbon, hydrogen, and oxygen. They are categorized into monosaccharides (simple sugars like glucose), disaccharides (complex sugars like sucrose, lactose, and maltose), and polysaccharides (complex forms like starch and cellulose). Carbohydrates serve various functions, from providing energy to forming supporting structures in plants and even contributing to the formation of DNA and other organic compounds.

-Examples of disaccharides include sucrose (found in sugar cane and sweet fruits), lactose (found in milk), and maltose (found in malted cereals and sprouting grains).
What is a condensation reaction in the context of carbohydrates?
-A condensation reaction in carbohydrates is a chemical process where two simple sugar molecules are joined together to form a larger molecule, with the removal of one molecule of water.
How does hydrolysis relate to disaccharides?
-Hydrolysis is a reaction where a disaccharide is broken down into monosaccharides by the addition of water, using a suitable enzyme.
What are polysaccharides and what are some examples?
-Polysaccharides are the most chemically complex carbohydrates, with examples including starch and cellulose.
What is the role of polysaccharides in the body?
-Polysaccharides like starch serve as a form of energy storage in plants and animals, while cellulose provides structural support in plant cell walls.

π Understanding Carbohydrates
Carbohydrates are organic compounds composed of carbon, hydrogen, and oxygen, and are a vital source of energy for the body. They are found in various forms in our daily lives, from food like bread and rice to cellulose in clothing. Carbohydrates serve multiple functions, including providing structural support in plants and being a component of DNA. They are categorized into three main types: monosaccharides (simple sugars like glucose with the formula C6H12O6), disaccharides (complex sugars composed of two monosaccharides, such as sucrose, lactose, and maltose), and polysaccharides (chemically complex carbohydrates like starch and cellulose). The formation of disaccharides involves a condensation reaction where two simple sugars combine, releasing a water molecule, while their breakdown is a hydrolysis reaction where water is added to split them into monosaccharides.

What are Carbohydrates? What are Its Different Types?
Carbohydrates and Its Types
We encounter many types of carbohydrates in our daily lives.
From bread to rice
and even to cellulose in our clothes.
Carbohydrates mainly come from plants
and are good sources of energy for the body.
They also function as supporting structures
like, for example
cellulose cell walls in plants.
They are used to make other organic compounds
like amino acids and fats
Nucleic acids like DNA are also formed by carbohydrates
as well as lubricants like mucus.
Another fascinating function of carbohydrates
is that they are also used to produce
the nectar in some flowers.
Carbohydrates are organic compounds
made of carbon, hydrogen and oxygen.
The hydrogen and oxygen atoms are present in the same ratio,
that is 2:1.
There are 3 main types of carbohydrates:
monosaccharides,
disaccharides
and polysaccharides.
Monosaccharides have a simple chemical composition
and therefore, knows as simple sugars.
Examples of them are glucose, fructose and galactose.
The sugar glucose is one of the simplest forms of sugars
and has the chemical formula C6H12O6.
The generalized formula for carbohydrates is CnH2mOm.
In the case of glucose,
n and m is also equal to 6.
Disaccharides are also known as complex sugars
as they have complex chemical compositions
Maltose, lactose and sucrose are their examples.
Disaccharides structure molecules
are made up of two molecules of simple sugars
condensed together.
The most common type of disaccharides
have 12 carbon atoms
with the general formula:
C12H22O11.
The differences in disaccharides
are again due to different atomic arrangements
within the molecule.
Sucrose or cane sugar
occurs in sugar cane stems,
sweet fruits
and certain storage roots,
for example carrots.
It consists of a glucose and a fructose molecule
combined together.
Lactose, also known as milk sugar
is commonly found in milk
as the name suggests.
It is found in milk of all mammals
including humans,
and even in some similar fluids,
such as pigeon's milk.
It is formed from glucose and galactose combined together.
Maltose, known as malt sugar,
is present in malted cereals and sprouting grains.
It is formed from the partial digestion of starch
and is a combination of two glucose molecules.
As mentioned before,
the formulation of one molecule of disaccharide
requires two molecules of simple sugars.
Each reaction is known as condensation reaction.
Condensation is a chemical reaction
whereby two simple molecules are joined together
to form a larger molecule
with the removal of one molecule of water.
On the other hand,
when a disaccharide is treated with a suitable enzyme,
it breaks down to form monosaccharides.
In this reaction,
water is added,
and thus the reaction is called hydrolysis,
or hydrolytic reaction.
Polysaccharides are the most chemically complex carbohydrates
and its examples include starch and cellulose.
There are other substances
which are slightly modified carbohydrates,
such as the chitin of the arthropod skeleton.
