Detailed explanation-1: -Lipids-polymers called diglycerides, triglycerides; monomers are glycerol and fatty acids. Proteins-polymers are known as polypeptides; monomers are amino acids.

Detailed explanation-2: -One of the oldest polymers prepared from triglyceride oils is alkyd resin produced by the esterification of polyhdroxy alcohols with polybasic acids and fatty acids (Fig. 2).

Detailed explanation-3: -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-4: -Triglycerides are a type of fat (lipid) found in your blood. When you eat, your body converts any calories it doesn’t need to use right away into triglycerides. The triglycerides are stored in your fat cells. Later, hormones release triglycerides for energy between meals.

Detailed explanation-5: -Triglycerides (TGs, also called neutral fats, triacylglycerols, or triacylglycerides) are a common, simple type of lipid consisting of three long-chain fatty acids esterified to glycerol [126]. There are exogenous (chylomicrons) and endogenous (pre--lipoproteins) triglycerides.
