Glucagon-like peptide-1 (GLP-1) is a neuropeptide and an incretin derived from the transcription product of the proglucagon gene.he known peripheral functions of GLP-1 include: 1  increases insulin secretion from the pancreas in a glucose-dependent manner. 2  increases insulin-sensitivity in both alpha cells and beta cells. 3  increases beta cells mass and insulin expression, PTM, and secretion.
Gluconeogenesis (GNG) is a metabolic pathway that results in the generation of glucose from non-carbohydrate carbon substrates such as pyruvate, lactate, glycerol, and glucogenic amino acids. The final reaction of gluconeogenesis, the formation of glucose, occurs in the lumen of the endoplasmic reticulum, where glucose-6-phosphate is hydrolyzed by glucose-6-phosphatase to produce glucose and release an inorganic phosphate.
