BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Assertion :Insulin is a globular protein. Reason: It has two polypeptide chains with 21 and 30 amino acids joined by sulphur bridges connecting cysteine amino acid on the two chains.

Detailed explanation-2: -Insulin is a protein consisting of two polypeptide chains, A chain and B chain, linked together by disulfide bonds.

Detailed explanation-3: -Biologically active insulin consists of two polypeptide chains, the A chain(21 amino acids) and the B chain(30 amino acids).

Detailed explanation-4: -Insulin is composed of two peptide chains referred to as the A chain and B chain. A and B chains are linked together by two disulfide bonds, and an additional disulfide is formed within the A chain. In most species, the A chain consists of 21 amino acids and the B chain of 30 amino acids.

Detailed explanation-5: -Insulin contains two peptide chains called the A chain and B chain. These two chains are linked together by two disulfide bonds, and also an additional disulfide is formed within the A chain. In almost every species of insulin, the A chain consists of 21 amino acids and the B chain of 30 amino acids.
