Takeaways

• 😀 Lipids are biological compounds that are nonpolar and insoluble in water. They are often referred to as fats in everyday language, but the term 'lipid' is more accurate as it includes various types like fats, phospholipids, steroids, and waxes.
• 😀 Fatty acids, a type of lipid, are long-chain organic acids that can be saturated (without double bonds) or unsaturated (with double bonds).
• 😀 Saturated fatty acids have single bonds in their carbon chain, making them solid at room temperature, whereas unsaturated fatty acids contain one or more double bonds and are usually liquid at room temperature.
• 😀 Fatty acids are categorized into essential and non-essential types. Essential fatty acids, like linoleic and linolenic acids, must be obtained through food as the body cannot synthesize them, while non-essential fatty acids can be produced by the body.
• 😀 The melting point of fatty acids increases with the length of their carbon chains. Longer chains result in higher melting points, while the presence of double bonds lowers the melting point.
• 😀 Fats are esters of fatty acids and glycerol. When three fatty acids bond with glycerol, they form triglycerides, commonly known as fats.
• 😀 There is a clear difference between fats and oils. Fats are typically solid at room temperature and come from animal sources, while oils are liquid at room temperature and generally come from plants.
• 😀 The process of hydrogenation turns unsaturated oils into saturated fats, which involves adding hydrogen to break the double bonds in the fatty acid chains.
• 😀 Saponification, or soap-making, is a reaction between fats or oils and a strong base (like NaOH), resulting in glycerol and soap.
• 😀 Phospholipids are similar to fats but contain a phosphate group instead of one fatty acid, and they are crucial components of cell membranes.
• 😀 Steroids, such as cholesterol and hormones like estrogen, progesterone, and testosterone, are another class of lipids. They have a structure composed of four interconnected carbon rings.
