一般描述

甘油是无味无色，具有粘性的甜味液体。它可以是天然来源，也可以来自石化原料。甘油具有广泛的应用，是自然界中最有价值和多功能的化学物质之一。它可用作润肤剂、溶剂、甜味剂，可用于药物配方、化妆品、食品和洗漱品中。它非常稳定，可以在常温下储存；它也无刺激性，对环境没有不良影响。

应用

甘油已被用作
  • 结核分枝杆菌 和 鸟分枝杆菌细胞培养过程中的补充剂；
  • 在设计酶生物燃料电池过程中的燃料；
  • 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；
  • 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

甘油本质上是吸湿的，并且由于其具有三个亲水性醇羟基而可溶于水。它可以形成分子间和分子内氢键，使其成为一种非常灵活的分子。 甘油的生理作用是由于其在细胞介导的免疫、增加的IgG产生、以及增加的组胺释放中的影响。
