What are the monomer units of a lipid?
A
Fatty acid
B
Amino Acid
C
Nucleotide
D
Sugar
Explanation: 

Detailed explanation-1: -The Glycerol and fatty acids are described as the monomers of lipids.

Detailed explanation-2: -Glycerol and fatty acids are the monomers of lipids. Lipids include waxes, oils and fats.

Detailed explanation-3: -Lipids technically do not have monomer units. They are neither polymers nor macromolecules. Different lipids will have different structures. Triglycerides, for example, are made of one glycerol molecule and three fatty acid tails.

Detailed explanation-4: -Lipids-polymers called diglycerides, triglycerides; monomers are glycerol and fatty acids. Proteins-polymers are known as polypeptides; monomers are amino acids.

Detailed explanation-5: -A fat molecule consists of two kinds of parts: a glycerol backbone and three fatty acid tails. Glycerol is a small organic molecule with three hydroxyl (OH) groups, while a fatty acid consists of a long hydrocarbon chain attached to a carboxyl group.
