Insulin vs. Glucagon

Insulinnoun

A polypeptide hormone that regulates carbohydrate metabolism.

Insulinnoun

hormone secreted by the isles of Langerhans in the pancreas; regulates storage of glycogen in the liver and accelerates oxidation of sugar in cells

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 glucose from the blood into liver, fat and skeletal muscle cells.

Glucagonnoun

(biochemistry) A peptide hormone, produced by the pancreas, that opposes the action of insulin by stimulating the production of sugar

Glucagonnoun

a hormone secreted by the pancreas; stimulates increases in blood sugar levels in the blood (thus opposing the action of insulin)

Glucagon

Glucagon is a peptide hormone, produced by alpha cells of the pancreas. It raises concentration of glucose and fatty acids in the bloodstream, and is considered to be the main catabolic hormone of the body.
