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 aspart Insulin aspart Insulin aspart is a fast-acting insulin analog marketed by Novo Nordisk as NovoLog/NovoRapid. It is a manufactured form of human insulin; where a single amino acid has been exchanged. This change helps the fast-acting insulin analog be absorbed quickly into the bloodstream. As a result, it starts working in minutes, which allows one to take insulin and eat right away. Fast-acting insulin analogs are considered to act similarly to the way insulin is released in people without diabetes mellitus. Novolog allows for a flexible dosing schedule, which allows patients to adjust their insulin according to any changes in
