Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the monomer (building block) of a protein?
A
amino acids
B
nucleotide
C
fatty acid
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: -For example, proteins are composed of monomers called amino acids.

Detailed explanation-3: -Amino acids are organic compounds consisting of carbon, hydrogen, and nitrogen. They are monomers or building blocks of proteins. Proteins are one of the major biomolecules required for the proper functioning of living organisms.

Detailed explanation-4: -The building blocks of proteins are amino acids, which are small organic molecules that consist of an alpha (central) carbon atom linked to an amino group, a carboxyl group, a hydrogen atom, and a variable component called a side chain (see below).

Detailed explanation-5: -Amino acids do not have single monomers. They are basic compounds bound to the same molecule, with an amino group and a group of carboxylic acids. Instead, amino acids are monomers of proteins, long chains of amino acids that are bound together by amide bonds.
