Insulin is a peptide hormone produced by beta cells in the pancreas. It regulates the metabolism of carbohydrates and fats; in addition, it stores fat to be used for energy later. When you eat, your blood sugar increases, which causes insulin to be released.
Insulin Synthesis and Secretion. Insulin is a small protein, with a molecular weight of about 6000 Daltons. It is composed of two chains held together by disulfide bonds. The figure to the right shows a molecular model of bovine insulin, with the A chain colored blue and the larger B chain green.
