Application
5-α-Cholestane has been used:
- as an internal standard in gas phase chromatography (GC) and high-performance liquid chromatography (HPLC) to quantify cholesterol in meat products for a comparison study
- to quantify the active compounds in the oils using a gas chromatograph coupled to a mass spectrometer
- as a reference standard in GC analyses to quantify sterol content in the unsaponifiables obtained from oat lipids and different sterol standards like fucosterol, sitosterol, campesterol, and stigmasterol
Biochem/physiol Actions
5α-Cholestane is a sterol produced endogenously from cholesterol and has been isolated from human feces. It is derived from cholesterol by the action of intestinal microorganisms. Derivatives of 5α-cholestane in plants are called brassinosteroids that selectively activate the PPI3K/Akt pathway.
Preparation Note
5α-Cholestane yields clear to slightly hazy, colorless to faint yellow solution in chloroform at 50 mg/ml.

The objectives of this study were to develop a GC-MS method for determination of cholesterol oxidation products (COPs) in tea-leaf eggs and study the formation and inhibition of COPs as affected by heating time and various ingredients in marinated juice.

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
