Glucagon-like peptide-1
Glucagon-like peptide-1
Glucagon-like peptide-1 (GLP-1) is a peptide hormone that plays a crucial role in regulating blood sugar levels. The term is derived from the Greek words glukus meaning sweet, agon meaning contest, and peptide which refers to a type of molecule made up of amino acids.
Pronunciation
Glu·ca·gon-like pep·tide-1
Etymology
The term "glucagon" is derived from glukus (Greek for sweet) and agon (Greek for contest). The term "peptide" is derived from peptos (Greek for digested), referring to a type of molecule made up of amino acids.
Function
GLP-1 is secreted by the L cells of the small intestine and colon in response to food intake. It stimulates the release of insulin from the pancreas, inhibits the secretion of glucagon (a hormone that raises blood sugar levels), and slows gastric emptying. This results in a decrease in blood sugar levels.
