There are 51 amino acids in an insulin molecule. It has a molecular weight of 5808 Da. Insulin is produced in the islets of Langerhans in the pancreas. The name insulin comes from the Latin ''insula'' for island from the cells that produce the hormone in the pancreas. Insulin's structure varies slightly between species of animal.
Insulin is a hormone produced by the beta cells of the pancreas that permits glucose to enter cells and helps the body use glucose for energy. Insulin controls the amount of glucose in the blood. People with Type 1 diabetes must use manufactured insulin, usually in an injectable form (such as an insulin pen or an insulin pump), to replace the natural insulin that is no longer produced by their body.
