一般說明

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。

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。
甘油已被用作
  • 一种在结核分枝杆菌鸟分枝杆菌的细胞培养中的补充剂。
  • 一种设计酶法生物燃料电池中的燃料。
  • 一种含有4-HCCA及3-氨基-喹啉并用于中性及酸性多糖分析的液体复合基质。
  • 一种用于快速原子轰击质谱的基质。
  • 可作为液体基质用于基于 MALDI(基质辅助激光解吸电离质谱)分析的定量研究。
