Aplicação
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
Ações bioquímicas/fisiológicas
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.
Nota de preparo
5α-Cholestane yields clear to slightly hazy, colorless to faint yellow solution in chloroform at 50 mg/ml.

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

Transmissible pathogens in source-separated human urine, intended for reuse in agriculture, mainly originate from faeces that cross-contaminate the urine. The health risks associated with the enteric pathogens will largely be dependent on their initial concentration and their inactivation during storage
