Collagen is a kind of protein, which belongs to glycoprotein, accounting for about 25% - 30% of the total protein in the human body. It mainly exists in connective tissue. It has strong stretching character, is the main component of ligament and extracellular matrix. Collagen contains hydroxylysine and hydroxyproline, which are not found in ordinary proteins. Hydroxyproline is a vehicle for transporting calcium from plasma to bone cells, which combines calcium with bone cells to prevent calcium loss that leads to bone osteoporosis.
