Gelatin Difference Between Collagen

Gelatin is a protein obtained by partial hydrolysis of collagen, gelatin and collagen with homology. Collagen has a rod-like three-stranded helical structure, when it is in the process of preparation of partially hydrolyzed gelatin, the partial separation of the triple helix structure of collagen and fracture. The amino acid composition of gelatin and collagen-similar, but because of differences in pretreatment, components may vary. Different specifications of the gelatin molecule 15000~250000Da by weight.
