Common NamePinocembrin
Description(S)-Pinocembrin, also known as dihydrochrysin, belongs to the class of organic compounds known as flavanones. Flavanones are compounds containing a flavan-3-one moiety, with a structure characterized by a 2-phenyl-3,4-dihydro-2H-1-benzopyran bearing a ketone at the carbon C3. Thus, (S)-pinocembrin is considered to be a flavonoid lipid molecule (S)-Pinocembrin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Outside of the human body, (S)-Pinocembrin is found, on average, in the highest concentration within mexican oregano (S)-Pinocembrin has also been detected, but not quantified in, pine nuts and prunus (cherry, plum). This could make (S)-pinocembrin a potential biomarker for the consumption of these foods. A dihydroxyflavanone in which the two hydroxy groups are located at positions 5 and 7. Pinocembrin is expected to be in Cannabis as all living plants are known to produce and metabolize it.

General function:
Involved in transferase activity, transferring hexosyl groups
Specific function:
UDPGT is of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This isoform glucuronidates bilirubin IX-alpha to form both the IX-alpha-C8 and IX-alpha-C12 monoconjugates and diconjugate. Is also able to catalyze the glucuronidation of 17beta-estradiol, 17alpha-ethinylestradiol, 1-hydroxypyrene, 4-methylumbelliferone, 1-naphthol, paranitrophenol, scopoletin, and umbelliferone.
