Detailed explanation-1: -Lipids that are important to our discussion include fats and oils (triglycerides or triacyglycerols), fatty acids, phospholipids, and cholesterol. Fats and oils are esters of glycerol and three fatty acids.
Detailed explanation-2: -Fats and oils are organic compounds that, like carbohydrates, are composed of the elements carbon (C), hydrogen (H), and oxygen (O), arranged to form molecules.
Detailed explanation-3: -Fats are hydrophobic hydrocarbon molecules consisting of fatty acids and glycerol. Glycerol has three carbons, each of which is attached to a hydroxyl group. Most fats are formed through replacement of the hydrogen of each hydroxyl group by a fatty acid.
Detailed explanation-4: -Simple lipids are esters of fatty acids with various alcohols. For eg., fats and waxes. On the contrary, complex lipids are esters of fatty acids with groups other than alcohol and fatty acids. For eg., phospholipids and sphingolipids.
