Detailed explanation-1: -Lipids-polymers called diglycerides, triglycerides; monomers are glycerol and fatty acids.

Detailed explanation-2: -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-3: -size, they are classified as macromolecules, big (macro-) molecules made through the joining of smaller subunits. Lipids are not usually polymers and are smaller than the other three, so they are not considered macromolecules by some sources 1, 2start superscript, 1, comma, 2, end superscript.
