Metabolite Identification
Common NamePatuletin
DescriptionPatuletin belongs to the class of organic compounds known as flavonols. Flavonols are compounds that contain a flavone (2-phenyl-1-benzopyran-4-one) backbone carrying a hydroxyl group at the 3-position. Thus, patuletin is considered to be a flavonoid lipid molecule. A trimethoxyflavone that is quercetagetin methylated at position 6. Patuletin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Outside of the human body, Patuletin has been detected, but not quantified in, a few different foods, such as german camomiles, herbs and spices, and spinachs. This could make patuletin a potential biomarker for the consumption of these foods.

General function:
Involved in magnesium ion binding
Specific function:
Catalyzes the O-methylation, and thereby the inactivation, of catecholamine neurotransmitters and catechol hormones. Also shortens the biological half-lives of certain neuroactive drugs, like L-DOPA, alpha-methyl DOPA and isoproterenol.

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.
