Common Name24-Methylene-24-dihydroparkeol
Description24-methylene-24-dihydroparkeol 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. 24-methylene-24-dihydroparkeol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). 24-methylene-24-dihydroparkeol can be found in cucumber and muskmelon, which makes 24-methylene-24-dihydroparkeol a potential biomarker for the consumption of these food products.
