Metabolite Identification

Common Name

4-Hydroxyphenyl acetate

Description

4-Hydroxyphenyl acetate, also known as hydroquinone monoacetate or 4-acetoxyphenol, belongs to the class of organic compounds known as phenol esters. These are aromatic compounds containing a benzene ring substituted by a hydroxyl group and an ester group. 4-Hydroxyphenyl acetate is an extremely weak basic (essentially neutral) compound (based on its pKa). 4-Hydroxyphenyl acetate exists in all living organisms, ranging from bacteria to humans. These are aromatic compounds containing a benzene ring substituted by an hydroxyl group and an ester group.

Enzymes

Enzyme Details

1. Serum paraoxonase/lactonase 3

General function:: Involved in arylesterase activity
Specific function:: Has low activity towards the organophosphate paraxon and aromatic carboxylic acid esters. Rapidly hydrolyzes lactones such as statin prodrugs (e.g. lovastatin). Hydrolyzes aromatic lactones and 5- or 6-member ring lactones with aliphatic substituents but not simple lactones or those with polar substituents.
Gene Name:: PON3
Uniprot ID:: Q15166
Molecular weight:: 39607.185

Reactions

4-Hydroxyphenyl acetate + Water → Hydroquinone + Acetic acid	details

Enzyme Details

2. Serum paraoxonase/arylesterase 1

General function:: Involved in arylesterase activity
Specific function:: Hydrolyzes the toxic metabolites of a variety of organophosphorus insecticides. Capable of hydrolyzing a broad spectrum of organophosphate substrates and lactones, and a number of aromatic carboxylic acid esters. Mediates an enzymatic protection of low density lipoproteins against oxidative modification and the consequent series of events leading to atheroma formation.
