Metabolite Identification
Common NameIsoketocamphoric acid
DescriptionIsoketocamphoric acid, also known as isoketocamphate, is a member of the class of compounds known as medium-chain fatty acids. Medium-chain fatty acids are fatty acids with an aliphatic tail that contains between 4 and 12 carbon atoms. Isoketocamphoric acid is slightly soluble (in water) and a weakly acidic compound (based on its pKa). Isoketocamphoric acid can be found in common sage, which makes isoketocamphoric acid a potential biomarker for the consumption of this food product.
