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.

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:

This study examines the effect of dietary supplementation with Lactobacillus acidophilus (LA) on the cholesterol levels, immune response, and productive performance of laying hens. A total of 216, 40-week-old, commercial Hy-Line brown chicken layers were randomly assigned into four treatment

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
