Identification
Common Namealpha-Sitosterol
ClassSmall Molecule
DescriptionAlpha-sitosterol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Alpha-sitosterol can be found in cocoa bean, common verbena, corn, and garden onion, which makes alpha-sitosterol a potential biomarker for the consumption of these food products.
