Metabolite Identification
Common Name3beta-Hydroxypregna-5,16-dien-20-one
Description3beta-hydroxypregna-5,16-dien-20-one, also known as 16-dehydropregnenolone or 5,16-pregnadien-3beta-ol-20-one, is a member of the class of compounds known as 20-oxosteroids. 20-oxosteroids are steroid derivatives carrying a C=O group at the 20-position of the steroid skeleton. Thus, 3beta-hydroxypregna-5,16-dien-20-one is considered to be a steroid lipid molecule. 3beta-hydroxypregna-5,16-dien-20-one is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). 3beta-hydroxypregna-5,16-dien-20-one can be found in fenugreek, which makes 3beta-hydroxypregna-5,16-dien-20-one a potential biomarker for the consumption of this food product.
