Metabolite Identification
Common Name(24S)-24-Methyl-25-dehydrocholesterol
Description(24s)-24-methyl-25-dehydrocholesterol 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, (24s)-24-methyl-25-dehydrocholesterol is considered to be a sterol lipid molecule (24s)-24-methyl-25-dehydrocholesterol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). (24s)-24-methyl-25-dehydrocholesterol can be found in french plantain, which makes (24s)-24-methyl-25-dehydrocholesterol a potential biomarker for the consumption of this food product.
