明胶(Gelatin)没有固定的结构和相对分子量, 由动物皮肤、骨、肌膜、肌魅等结缔组织中的胶原部分降解而成为白色或淡黄色、半透明、微带光泽的薄片或粉粒,是一种无色无味,无挥发性、透明坚硬的非晶体物质,可溶于热水,不溶于冷水,但可以缓慢吸水膨胀软化,明胶可吸收相当于重量 5-10 倍的水。明胶的主要组成为氨基酸组成相同而分子量分布很宽的多肽分子混合物,分子量一般在几万至十几万。明胶既具有酸性,又具有碱性,是一种两性物质,明胶的胶团是带电的,在电场作用下,它将向两极中的某一极移动。明胶分子结构上有大量的羟基,另外还有许多羧基和氨基,这使得明胶具有极强的亲水性。明胶是是非常重要的天然生物高分子材料之一,已被广泛应用于食品、医药及化工产业。

Gelatin has no fixed structure or relative molecular mass. It is degraded from collagen in connective tissues such as animal skin, bones, sarcolemma and fascia, forming white or pale yellow, translucent and slightly glossy flakes or particles. As a colorless, odorless, non-volatile, transparent and hard amorphous substance, it dissolves in hot water but not cold water, and slowly absorbs water to swell and soften, absorbing water 5 to 10 times its own weight.Gelatin is mainly a mixture of polypeptides with identical amino acid compositions and broad molecular weight distribution, ranging from tens of thousands to hundreds of thousands. It is amphoteric with both acidic and alkaline properties. Its colloidal particles carry electric charges and migrate towards one electrode under an electric field. Abundant hydroxyl, carboxyl and amino groups in its molecular structure endow gelatin with strong hydrophilicity. As an important natural biological macromolecular material, gelatin is widely used in food, pharmaceutical and chemical industries.
