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。

應用

甘油可用作:
  • 免疫荧光封固剂成分
  • 结核分枝杆菌鸟分枝杆菌细胞培养过程中的补充剂;
  • 酶生物燃料电池设计过程中的燃料;
  • 含有4-HCCA和3-氨基­喹啉的液体复合基质,可用于分析中性和酸性聚糖;
  • 进行快原子轰击电离质谱的基质;
甘油可用作MALDI(基质辅助激光解吸/电离质谱)定量分析研究的液体基质。

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。
