IUPAC 名称
14-(5,6-dimethylhept-3-en-2-yl)-2,15-dimethyltetracyclo[8.7.0.0²,⁷.0¹¹,¹⁵]heptadec-7-en-5-ol
描述
Crinosterol 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. Crinosterol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Crinosterol can be found in a number of food items such as grass pea, burdock, arrowroot, and jicama, which makes crinosterol a potential biomarker for the consumption of these food products. Epibrassicasterol (also called crinosterol) is a type of cholesterol most commonly found in marine invertebrates. Epibrassicasterol is a 28 carbon cholesterol with an alpha oriented methyl group at carbon 24. It is often mixed isomerically with the more common beta-isomer, brassicasterol. Epibrassicasterol can be used as a biomarker to identify the presence of marine life in an environment and can be dated based on the location of fossilized remains in various rock structures .
