Chitin role of traditional Chinese medicine called "stasis" means gas, blood, water is not flowing sick. Peripheral circulation bad price when bleeding chitin, body surface temperature decreases and becomes cold symptoms. Due to poor peripheral circulation chitin shelf life of muscle cells nutrients, lack of oxygen supply of chitin, the accumulation of metabolic waste, can cause back pain. Chitosan in the body decomposition products glucosamine can stimulate the vagus nerve Weifang chitin sales, parasympathetic excitement, the blood vessels dilate, thus chitin will improve back pain. Chitin is a polymer molecular weight substances having a molecular weight of up to 100 million or more. The higher molecular weight of the stronger adsorption capacity for industrial and environmental protection applications. Low molecular weight is easily absorbed by the body. Molecular weight of chitosan about 7000, about 30 or so containing glucosamine residues. Deacetylase purity chitin deacetylase after becoming chitosan. Chitin because they do not dissolve in water, soluble in acid nor the body which can not be used. After deacetylation thus increase its solubility can be absorbed by the body. N- acetyl-off of more than 55% is called chitosan. Weifang sales chitin, chitin, Marvell Marvell biotechnology provided by Shouguang biotechnology company.
