Chemical Information
FooDB Name(+)-Hardwickiic acid
Description(+)-hardwickiic acid is a member of the class of compounds known as colensane and clerodane diterpenoids. Colensane and clerodane diterpenoids are diterpenoids with a structure based on the clerodane or the colensane skeleton. Clerodanes arise from labdanes by two methyl migrations (+)-hardwickiic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). (+)-hardwickiic acid can be found in blackcurrant, which makes (+)-hardwickiic acid a potential biomarker for the consumption of this food product.
