LIFE SCIENCE

Detailed explanation-1: -For example, proteins are composed of monomers called amino acids. They are linked together to form a polypeptide chain, which folds into a three dimensional (3D) structure to constitute a functional protein (Figure 1).

Detailed explanation-2: -The name “amino acid” is derived from the fact that they contain both amino group and carboxyl-acid-group in their basic structure. As mentioned, there are 20 amino acids present in proteins.

Detailed explanation-3: -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.

Detailed explanation-4: -Monomeric proteins are protein molecules that combine to form multi-protein complexes. Biopolymers are polymers consisting of organic monomers found in living organisms.

Detailed explanation-5: -Building Blocks or Elementary Units: Proteins Monomers The order of amino acids in which they are arranged is called the primary structure of a protein. Chemically speaking, an amino acid molecule consists of three groups, i.e., amino group (-NH2), carboxylic acid group (-COOH), and side-chain (R group).
