一般描述

甘油是一种无味无色并具有甜味的液体，在自然状态下具有黏性。它可以是自然存在的，也能衍生自石油化工原料。甘油具有十分广泛的应用，是自然中最具价值以及多功能性的化学物质之一。它可用作润肤剂、溶剂、甜味剂用于药物配方、化妆品、食品和化妆品中。它非常稳定且非常易于在常温下进行储存；它也没有刺激性，对环境没有不良影响。

应用

甘油可用作免疫荧光封固剂成分，还可用作聚(3,4-乙撑二氧噻吩)聚苯乙烯磺酸盐(PEDOT:PSS)基油墨的添加剂。

生化/生理作用

甘油天然具有是吸湿性，并因其三个亲水性醇羟基而可溶于水。它可形成分子间及分子内的氢键，使其成为一种非常灵活的分子。 甘油的生理作用与细胞介导的免疫、IgG生成的提高以及增加的组胺释放相关。
