As the most abundant and widely distributed functional macromolecular protein in mammals,collagen mainly exists in the connective tissues of animals and participates in the composition of extracellular matrix structure,which is difficult for human body to directly digest and absorb.Collagen peptide(CP)is a mixture between amino acids and proteins obtained by enzymatic hydrolysis of collagen.It is widely used in medical and food fields due to its advantages of good antioxidant activity,biocompatibility,low molecular weight and easy digestion and absorption.This article mainly reviews the function and mechanism of CP in preventing osteoporosis,repairing skin aging and preventing type Ⅱ diabetes from CP sources,in order to pro-vide new ideas for professionals engaged in CP research and development.
