A, different nature

1, fibrin: by three pairs of polypeptide chains (a pair of α-chain, a pair of β-chain, a pair of γ-chain) to disulfide bonds connected by dimers.

2, cellulose: a macromolecular polysaccharide composed of glucose.

Two, the role of different

1, fibrin role: hemostasis, in addition to significantly promote wound healing, can also be used as a bone to promote cell growth; and has a certain bactericidal effect.

2, the role of cellulose: the human body does not have β-glucosidase, it can not decompose and use cellulose, but cellulose can absorb a lot of water, increase the amount of feces, promote intestinal peristalsis, accelerate fecal excretion.

Expansion of information:

Cellulose chemistry and industry began more than one hundred and sixty years ago, and it has been the main object of research in the birth and development of polymer chemistry. The research results of cellulose and its derivatives have made important contributions to the establishment, development and enrichment of polymer physical chemistry.

Due to the shortage of forest resources in China, 70% of cellulose raw materials come from non-wood resources. The average cellulose content of coniferous and broadleaf timber is about 43-45%, and the average cellulose content of grass straw is about 40%.
