Collagen is the most abundant functional protein in mammals, which exists in various tissues and organs, especially in connective tissue, ligament, achilles tendon, skin, cartilage, blood vessels and so on. According to the sequence of discovery and amino acid sequence of collagen, collagen family can be divided into 28 types, among which type Ⅰ, Ⅱ and Ⅲ collagen account for more than 90% of the total collagen. Unlike the simple structure of ordinary proteins, collagen consists of three alpha chains, which are themselves left handed helices, twisted into a right handed triple helix structure. With age and exposure to UV rays, collagen, the main component of skin, is lost. After age 20, collagen in the skin drops by 7% every 10 years. In particular, the loss of type Ⅲ collagen can lead to rough, aging skin.
