甲壳质(甲壳素)广泛存在于虾、蟹的外壳、昆虫外皮以及真菌的细胞壁中,是大自然赋予人类的除淀粉、植物纤维素外的第三大生物资源。就化学结构而言,甲壳质是氨基多糖,因其结构与植物纤维近似,又源于动物,能被生物降解,因此也被定义为动物纤维素,在种植业中表现出来的优点很多。 Chitin (chitin) is widely found in shrimp and crab shells, insect sheaths and fungal cell walls. It is the third largest biological resource that is conferred by nature to humans except starch and plant cellulose. In terms of chemical structure, chitin is an aminopolysaccharide, and because its structure is similar to that of plant fibers, it is also derived from animals and is biodegradable. Therefore, chitin is also defined as animal cellulose, and has many advantages in the field of plantation.
