甲壳质(Chitin)又名甲壳素是一种天然高分子聚合物,化学名:聚N—乙酸葡萄糖胺。广泛存在于无脊椎动物的外壳、昆虫的外角质层和内角质层,真菌的胞壁中,自然界每年生物合成的甲壳质估计有数十亿吨,是目前地球上第二大类有机资源。甲壳质脱去分子的乙酰基就转变为壳聚糖(CHITOSAN)。分子量:161(单体)≤10000(低聚)≤300000(聚糖) 壳聚糖又称聚氨基葡萄糖,属于天然高分子聚糖。由于它的化学结构中含有活性自由氨基,赋予它许多特殊的性质,易形成聚阳离子,与人体细胞具有亲和性,因此使它具有多种生物活性,如活化修复细
Chitin, also known as chitin, is a kind of natural high molecular polymer with the chemical name of poly-N-acetylglucosamine. Widespread in the invertebrate shell, the outer stratum corneum and the stratum corneum, fungal cell wall, the annual biosynthesis of chitin in nature is estimated at billions of tons, is currently the second largest class of organic resources on Earth. Chitin off the acetyl group into chitosan (CHITOSAN). Molecular weight: 161 (monomer) ≤ 10000 (oligo) ≤ 300000 (polysaccharide) Chitosan, also known as polyglucosamine, is a natural high molecular weight polysaccharide. Because of its chemical structure contains free amino active, giving it many special properties, easy to form polycation, and human cells have affinity, so it has a variety of biological activity, such as activation and repair of fine
