Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which is the monomer (building block) for lipids?
A
fatty acids & glycerol
B
nucleotide
C
amino acids
D
monosaccharide
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: -The monomers of the lipids are glycerol. Fatty acids are found in animal bodies as well as in plants. Unsaturated and saturated fatty acids occur naturally in living beings. Few examples of fatty acids are oil and steroids.

Detailed explanation-3: -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. Glycerol is a thick, smooth, syrupy compound that is often used in the food industry. To form a triglyceride, a glycerol molecule is joined by three fatty acid chains.

Detailed explanation-4: -Fats are made of a molecule of glycerol bonded to three fatty acid chains, which can vary in length and bond type. The monomer units of fats are glycerol and the fatty acids that attach to the glycerol. The fatty acids vary in length, and some of them can even have bends.
