Detailed explanation-1: -A lipid is a polymer composed of three fatty acid molecules and one glycerol molecule. Lipids produce a special polymer form which is considered to be a key component of cell membranes and hormones. Lipids help to store energy, provide cushion, protect tissues, separate the body, and form membranes of cells.

Detailed explanation-2: -One major class of lipids is called glycerolipids. Glycerolipids are composed of glycerol and fatty acids.

Detailed explanation-3: -A lipid is a polymer made up of three molecules of fatty acids and one molecule of glycerol. They are the main constituents of body fat in humans and other animals, as well as vegetable fat.

Detailed explanation-4: -Lipids have four main types of polymers: triglycerides, phospholipids, waxes, and steroids. Triglycerides are made of a glycerol backbone and three fatty acid tails that differ in length and orientation. Triglycerides with single-bonded carbons are called saturated fats.

Detailed explanation-5: -Fats and oils are esters of glycerol and three fatty acids. They are important in the diet as energy sources and as sources of essential fatty acids and fat-soluble vitamins, which tend to associate with fats. They also contribute satiety, flavor, and palatability to the diet.
