BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Amino acids are the smallest and basic structural units of proteins. Amino acids of same or different types combine together to form a polypeptide chain and many polypeptide chains, in turn, join to form a complex structure called protein.

Detailed explanation-2: -The amino acids are joined to form a long chain of acids by amino and carboxyl and yields water. This long chain amino acids is the primary protein. The primary proteins modify into different directions to form secondary, tertiary etc., proteins.

Detailed explanation-3: -True. Proteins are composed of amino acids. The amino acids that comprise proteins are connected via peptide linkages.

Detailed explanation-4: -In the human body, there are 20 amino acids that function as building blocks of proteins.

Detailed explanation-5: -Scientists have identified approximately 500 naturally occurring amino acids, of which only 20 are used to make proteins in the human body, earning them the sobriquet proteinogenic amino acids. These 20 amino acids link together in varying combinations to form different types of protein.
