应用
5-α-胆甾烷已用于：
- 作为气相色谱（GC）和高效液相色谱（HPLC）的内标，用于定量肉制品中的胆固醇，从而进行比较研究
- 通过质谱和气相色谱联用对油中的活性化合物进行定量分析
- 作为 GC 分析中的参考标准，对从燕麦脂质和不同甾醇标准品（如岩藻甾醇、谷甾醇、樟脑甾醇和豆甾醇）中获得的不皂化物中的甾醇进行定量分析
生化/生理作用
5α-胆甾烷是一种胆固醇内生甾醇，从人类粪便中分离得到。它是肠道微生物作用于胆固醇而产生的。植物中的5α-胆甾烷衍生物被称为油菜素类固醇，可选择性激活 PPI3K/Akt 途径。
制备说明
50 mg/ml的5α-胆甾烷氯仿溶液澄清至略微混浊，无色至淡黄色。

The profile of bioactive compounds (carotenoids, tocopherols, tocotrienols, phytosterols, and squalene) in oils recovered from the kernels of 28 plum varieties of hexaploid species Prunus domestica L. and diploid plums Prunus cerasifera Ehrh. and their crossbreeds were studied. Oil yields

Nutritional enhancement of crops using genetic engineering can potentially affect herbivorous pests. Recently, oilseed crops have been genetically engineered to produce the long-chain omega-3 polyunsaturated fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) at levels similar to that found

In this study, we evaluated whether oil extracted from the marine microbe, Schizochytrium sp. (strain T18), with high levels of docosahexaenoic acid (DHA), could replace fish oil (FO) in diets for rainbow trout (Oncorhynchus mykiss). Three experimental diets were tested:
