Correct Answer:
Option C - Proteins are made up of compounds called amino acids. So they are known as the building components of protein. Amino acids are the necessary ingredients for the growth and development of human. Basic amino groups (–NH₂) and carboxyl groups (–COOH) are found in amino acids. Long chains of amino acids constitute peptides and proteins. Proteins are made up of twenty amino acids.
