Chemical properties of collagen;

Collagen is a white transparent powder with slender rod-shaped molecules, and its relative molecular weight ranges from about 2kD to 300kD. Collagen has strong ductility, is insoluble in cold water, dilute acid and dilute alkali solution, and has good water retention and emulsification.

Collagen is not easily hydrolyzed by ordinary protease, but can be decomposed by animal collagenase, and the decomposed fragments automatically denature and can be hydrolyzed by ordinary protease. When the environmental pH is lower than neutral, the denaturation temperature of collagen is 40 ~ 465438 0℃, and when the environmental pH is acidic, the denaturation temperature is 38~39℃.
