实际上不溶于水,溶于苯,溶解度: 1g/660 ml 醇 - 1g/45 ml 沸醇,1g/70 ml 醚 - 1g/39 ml 沸醚,1g/32 ml 氯仿。角固醇是微生物细胞膜的重要组成部份，对确保细胞膜的完整性，膜结合酶的活性，膜的流动性，细胞活力以及细胞物质运输等起着重要作用。 Ergosterol or provitamin D2 is a biological precursor of Vitamin D2. It is found predominantly in cell membranes of fungi and protists such as trypanosomes. Ergosterol 是真菌中的主要固醇类，具有抗氧化，抗增殖和抗炎的作用。 Dihexadecyl phosphate (DHP) is a negatively charged lipid that is used for the formation of model membranes. application： Ergosterol has been used: as a component of yeast cell monolayer models, to study the effects of steroidal and triterpenoid saponins on the monolayers as a standard sample, to isolate and identify a fungal metabolite fraction containing ergosterol as a component of the culture medium to isolate the CYP51RNAi phenotype of Trypanosoma brucei gambiense, to verify ergosterol biosynthesis
