壳聚搪(几丁聚糖):化学名(1.4)-2-氨基-2-脱氧-B-D-葡萄糖,是海洋节肢类动物(如虾、蟹)、昆虫和其他无脊椎动物外壳中的甲壳质(甲壳素),经脱乙酚制得一种天然的水溶性高分子聚合物。是目前自然界中发现的惟一含游离氨基碱性基团的阳离子可食性动物纤维。壳聚糖是水溶性物质,它在人体内分解产物是葡萄搪胺,葡萄糖胺是人体透明质酸和细胞膜的重要成分,与人体有良好的亲和力,能直接被人体吸收,生物利用率高,在人体中发挥着重要作用:——电荷中和(吸附)作用:壳聚糖的大量正电荷在体内与带负电的致病因子(如:胆固醇、甘油三脂、自由基、氯离子、重金属离子等),形成稳定离子键,抑制致病因子的功能并将其排除体外。——酸碱中和调节作用:壳聚糖的碱性基团与酸性物质中和,纠正体液酸化,去除酸性致病因素,同时释放无毒的高能量、高活性生物基质-葡萄糖胺。——活化细胞功能作用:葡萄糖胺(是细胞膜和透明质胶的重要组成基
Chitosan (chitosan): Chemical name (1.4) -2-amino-2-deoxy-BD-glucose, is the carapace in marine arthropods such as shrimp, crab, insects and other invertebrate shells Quality (chitin), prepared by de-catechin a natural water-soluble polymer. Is the only cationic edible animal fiber found in nature containing free amino basic groups. Chitosan is a water-soluble substance, which is the decomposition product in the human body is grape amine, glucosamine is an important component of human hyaluronic acid and cell membranes, and the human body has good affinity, can be directly absorbed by the body, bioavailability, Plays an important role in the human body: - charge neutralization (adsorption) effect: a large number of positive charge of chitosan in the body and negatively charged virulence factors (such as: cholesterol, triglycerides, free radicals, chloride, heavy metals Ions, etc.), the formation of stable ionic bond, inhibit the function of causal agents and exclude them in vitro. - Acid-base neutralization: Chitosan’s basic groups are neutralized with acidic substances to correct body fluid acidification, remove acidic pathogenic factors, and release nontoxic, high-energy, high-activity biological substrate - glucosamine. - Activation of cell function: Glucosamine (an important constituent of cell membranes and hyaluronan
