Identification
Common Name24-Ethyl-trans-22-dehydrocholesterol
ClassSmall Molecule
Description24-ethyl-trans-22-dehydrocholesterol belongs to stigmastanes and derivatives class of compounds. Those are sterol lipids with a structure based on the stigmastane skeleton, which consists of a cholestane moiety bearing an ethyl group at the carbon atom C24. 24-ethyl-trans-22-dehydrocholesterol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). 24-ethyl-trans-22-dehydrocholesterol can be found in sunflower, which makes 24-ethyl-trans-22-dehydrocholesterol a potential biomarker for the consumption of this food product.
