fecosterol
IUPAC 名称
(2S,5S,7S,11R,14R,15R)-2,15-dimethyl-14-[(2R)-6-methyl-5-methylideneheptan-2-yl]tetracyclo[8.7.0.0^{2,7}.0^{11,15}]heptadec-1(10)-en-5-ol
描述
Fecosterol, also known as 24-methylene-5alpha-cholest-8-en-3beta-ol or delta-8(24),28-ergostadienol, belongs to ergosterols and derivatives class of compounds. Those are steroids containing ergosta-5,7,22-trien-3beta-ol or a derivative thereof, which is based on the 3beta-hydroxylated ergostane skeleton. Thus, fecosterol is considered to be a sterol lipid molecule. Fecosterol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Fecosterol can be synthesized from 5alpha-ergostane. Fecosterol can also be synthesized into fecosterol ester. Fecosterol can be found in a number of food items such as jew's ear, lima bean, persimmon, and european plum, which makes fecosterol a potential biomarker for the consumption of these food products. Fecosterol may be a unique S.cerevisiae (yeast) metabolite. Fecosterol is a sterol made by certain fungi and lichens .
