Summary Introduction
Introduction:
Insulin is a hormone composed of two polypeptide chain A and B, which are joined by disulfide bonds. The synthetic insulin is used by many diabetic patients to regulate their blood sugar levels. The production of human insulin in the Escherichia coli (E. coli) is a significant discovery in
