Insulin hormone Edit

«Insulin (from Latininsula, island) is a peptide hormone produced by beta cell of the pancreatic islets; it is considered to be the main anabolic hormone of the body.[5] It regulates the metabolism of carbohydrate, fat and protein by promoting the absorption of carbohydrate, especially glucose from the blood into liver, fat and skeletal muscle cell.[6] In these tissues the absorbed glucose is converted into either glycogen via glycogenesis or fat (triglyceride) via lipogenesis, or, in the case of the liver, into both.[6]Glucose production and secretion by the liver is strongly inhibited by high concentration of insulin in the blood.[7] Circulating insulin also affects the synthesis of proteins in a wide variety of tissues. It is therefore an anabolic hormone, promoting the conversion of small molecules in the blood into large molecules inside the cell. Low insulin levels in the blood have the opposite effect by promoting widespread catabolism, especially of reserve body fat.
