Insulin is a hormone that regulates the amount of glucose in the blood and is required for the body to function normally. The gene that codes for the production of insulin is located in the short arm of chromosome 11. It has a total of 51 amino acids and 2 polypeptide chains called A and B. Insulin is produced by cells in the pancreas, called the islets of Langerhans. These cells continuously release a small amount of insulin into the body, but they release surges of the hormone in response to a rise in the blood glucose level. insulin production https://microbiosci.creative-biogene.com/insulin-fermentation.html
