MOTS-c(human) belongs to one of the mitochondrial derived peptides (MDP). The main physiological function is to promote the biosynthesis of endogenous AMP analogue AICAR, thereby promoting AMP-activated protein kinase (AMPK), and enhancing the induction of glucose uptake by cells and improving insulin sensitivity. As a drug raw material, it is a potential weight loss polypeptide raw material, and has a good anti-aging effect (refer to the relevant literature)
