Metabolite Identification
Common NameCurcumin III
DescriptionCurcumin III belongs to the class of organic compounds known as 1-hydroxy-2-unsubstituted benzenoids. These are phenols that are unsubstituted at the 2-position. Curcumin III has been detected, but not quantified in, herbs and spices. This could make curcumin III a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Curcumin III.
