Collagen is the main protein of connective tissue and inner skin layer in animals, and the most abundant brous protein in mammals, making up about 90% of the main protein component of the bone. Generally, collagen is used in medical care and in cosmetics, it is an animal's bone and skin extracts. It is a macromole-cule protein, which is made of triple helix structures. The triple helix is composed of three polypeptide chains about 100,000 molecular weight.

NanoCollagen changes into a low molecule by a ferment resolution, a digestion absorptance high. It's average molecular weight is about 400Da, specic gravity in appearance is over 0.5. So it compares in the other product and the insect position characteristic is good and the dust to be few work characteristic is superior it.
