Question

A lipid is a polymer made up of

• A. Modified glucose molecules
• B. Amino acids
• C. Nucleotides
• D. Fatty acids and glycerol

Answer 1

Answer: (D)

Fatty acids and glycerol

A lipid is a polymer made up of three molecules of fatty acids and one molecule of glycerol. They are the main constituents of body fat in humans and other animals, as well as vegetable fat.

Glucose molecules are the monomers for polysaccharides.

Amino acids are the monomer of the polypeptide chain or proteins. There are 20 amino acids that form the different type of proteins.

Nucleotides are the monomers of the nucleic acids i.e. DNA and RNA.

So, the correct option is 'Fatty acids and glycerol'.
