What is the monomer (building block) of lipids?
A
nucleotides
B
amino acids
C
triglycerides
D
monosaccharides
Explanation: 

Detailed explanation-1: -Monomers are the building blocks of the four basic macromolecules of life-monosaccharides are the monomers of carbohydrates, amino acids are the monomers of proteins, glycerol/fatty acids are the monomers of lipids, and nucleotides are the monomers of DNA.

Detailed explanation-2: -Lipids’ monomers are glycerol and fatty acids. The glycerol makes the backbone of a triglyceride, a common lipid polymer. Three fatty acids make the long fatty chains of triglyceride.

Detailed explanation-3: -The building blocks of triglycerides are 3 fatty acids attached to a backbone of glycerol (glycerine). When fats are eaten the digestive enzymes break down the molecules into separate fatty acids and glycerol again.

Detailed explanation-4: -Triglycerides Structure and Functions Triglycerides are the main form of lipid found in the body and in the diet. Fatty acids and glycerol are the building blocks of triglycerides.

Detailed explanation-5: -Lipids-polymers called diglycerides, triglycerides; monomers are glycerol and fatty acids.
