Abstract

Aglycin, a natural peptide extracted from legume seeds such as pea and soybean, is composed of 37 amino acids with highly conserved amino acid residues. It has strong resistance to the hydrolysis of digestive proteases to reveal the excellent stability. Aglycin has an obvious function of stimulating intestinal insulin signaling like GLP-1, thereby promoting the synthesis and secretion of insulin, and reducing blood glucose level in an animal model with hyperglycemia. Meanwhile, it also has anti-inflammatory functions in islets to protect the aging and damage of islet beta cells. The underlying mechanisms are highly correlated with the biosynthesis of glucose transporter-4 and the activation of the insulin receptor, as well as the enhanced insulin sensitivity. Moreover, this polypeptide also can promote 尾-oxidation of fatty acids in hepatocytes and inhibit the production of hepatocytes. Taken together, aglycin can be used as a potential oral polypeptide drug or supplements to prevent and treat diabetes and non-alcoholic fatty liver disease.
