Detailed explanation-1: -Lipids are an essential component of the cell membrane. The structure is typically made of a glycerol backbone, 2 fatty acid tails (hydrophobic), and a phosphate group (hydrophilic).

Detailed explanation-2: -Glycerol and fatty acids are the basic building blocks of fats (lipids).

Detailed explanation-3: -Triacylglycerols are the main form of lipid found in the body and in the diet. Fatty acids and glycerol are the building blocks of triacylglycerols. Glycerol is a thick, smooth, syrupy compound that is often used in the food industry. To form a triacylglycerol, a glycerol molecule is joined by three fatty acid chains.

Detailed explanation-4: -The building block of lipids is a glycerol molecule. Glycerol is an alcohol molecule with three hydroxyl groups (-OH). These hydroxyl groups are reactive and can form ester bonds with fatty acids. When three fatty acids bond with a glycerol molecule through ester bonds, a triacylglycerol (or triglyceride) is formed.

Detailed explanation-5: -Lecithin, for example, is made up of glycerol, two fatty acids (one saturated, usually), phosphate, and choline. Phospholipids are important structural components of brain and nervous tissue, of membranes throughout body tissues, and of lipoproteins-the carriers of cholesterol and fats in the blood.
