Insulin Insulin Insulin (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. It regulates the metabolism of carbohydrates, fats and protein by promoting the absorption of carbohydrates, especially glucose from the blood into liver, fat and skeletal muscle cells. 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. Glucose production and secretion by the liver is strongly inhibited by high concentrations of insulin in
Insulin glargine help offer moderate control of serum glucose levels. In the absence of endogenous insulin—type 1 diabetes, depleted type 2 (in some cases) or latent autoimmune diabetes of adults in late stage—insulin glargine needs the support of fast acting insulin taken with food to reduce the effect of prandially derived glucose (from food). The long-acting insulin class, which includes insulin glargine, do not appear much better than neutral protamine Hagedorn (NPH) insulin but have a significantly greater cost making them, as of 2010, not cost effective for the treatment of type 2 diabetes. It is unclear if there is a difference
