Insulin - Wikipedia - en.wikipedia.org  ## Metadata - Author: **en.wikipedia.org** - Full Title: Insulin - Wikipedia - Category: #articles - URL: https://en.wikipedia.org/wiki/Insulin ## Highlights - Insulin (/ˈɪn.sjʊ.lɪn/,[5][6] from Latin insula, 'island') is a peptide hormone produced by beta cells of the pancreatic islets; it is considered to be the main anabolic hormone of the body.[7] It regulates the metabolism of carbohydrates, fats and protein by promoting the absorption of glucose from the blood into liver, fat and skeletal muscle cells.[8] In these tissues the absorbed glucose is converted into either glycogen via glycogenesis or fats (triglycerides) via lipogenesis, or, in the case of the liver, into both.[8] Glucose production and secretion by the liver is strongly inhibited by high concentrations of insulin in the blood
