MICROANATOMY

Detailed explanation-1: -Insulin is a protein composed of two chains, an A chain (with 21 amino acids) and a B chain (with 30 amino acids), which are linked together by sulfur atoms. Insulin is derived from a 74-amino-acid prohormone molecule called proinsulin.

Detailed explanation-2: -The function which was not performed by the insulin is to Initiate the conversion of glycogen to glucose.

Detailed explanation-3: -Insulin is a small protein, but contains almost all structural features typical of proteins: -helix, -sheet, -turn, high order assembly, allosteric T®R-transition, and conformational changes in amyloidal fibrillation.

Detailed explanation-4: -rapid-acting insulin. short-acting insulin. intermediate-acting insulin. mixed insulin. long-acting insulin.
