Metabolite Identification
Common Namep-Hydroxyphenylacetic acid
Descriptionp-Hydroxyphenylacetic acid, also known as 4-hydroxybenzeneacetate, is classified as a member of the 1-hydroxy-2-unsubstituted benzenoids. 1-Hydroxy-2-unsubstituted benzenoids are phenols that are unsubstituted at the 2-position. p-Hydroxyphenylacetic acid is considered to be slightly soluble (in water) and acidic.  p-Hydroxyphenylacetic acid can be synthesized from acetic acid. It is also a parent compound for other transformation products, including but not limited to, methyl 2-(4-hydroxyphenyl)acetate, ixerochinolide, and lactucopicrin 15-oxalate.  p-Hydroxyphenylacetic acid can be found in numerous foods such as olives, cocoa beans, oats, and mushrooms. p-Hydroxyphenylacetic acid can be found throughout all human tissues and in all biofluids. Within a cell, p-hydroxyphenylacetic acid is primarily located in the cytoplasm and in the extracellular space. p-Hydroxyphenylacetic acid is also a microbial metabolite produced by Acinetobacter, Clostridium, Klebsiella, Pseudomonas, and Proteus. Higher levels of this metabolite are associated with an overgrowth of small intestinal bacteria from Clostridia species including C. difficile, C. stricklandii, C. lituseburense, C. subterminale, C. putrefaciens, and C. propionicum (PMID: 476929 , 12173102 ). p-Hydroxyphenylacetic acid is detected after the consumption of whole grain.

Enzymes

General function:
Involved in oxidoreductase activity
Specific function:
ALDHs play a major role in the detoxification of alcohol-derived acetaldehyde. They are involved in the metabolism of corticosteroids, biogenic amines, neurotransmitters, and lipid peroxidation. This protein preferentially oxidizes aromatic aldehyde substrates. It may play a role in the oxidation of toxic aldehydes.
Gene Name:
ALDH3A1
Uniprot ID:
P30838
Molecular weight:
50394.57
Reactions
4-Hydroxyphenylacetaldehyde + NAD + Water → p-Hydroxyphenylacetic acid + NADH + Hydrogen Iondetails
4-Hydroxyphenylacetaldehyde + NADP + Water → p-Hydroxyphenylacetic acid + NADPH + Hydrogen Iondetails
General function:
Involved in oxidoreductase activity
Specific function:
Recognizes as substrates free retinal and cellular retinol-binding protein-bound retinal. Seems to be the key enzyme in the formation of an RA gradient along the dorso-ventral axis during the early eye development and also in the development of the olfactory system (By similarity).
Gene Name:
ALDH1A3
Uniprot ID:
P47895
Molecular weight:
56107.995
Reactions
4-Hydroxyphenylacetaldehyde + NAD + Water → p-Hydroxyphenylacetic acid + NADH + Hydrogen Iondetails
4-Hydroxyphenylacetaldehyde + NADP + Water → p-Hydroxyphenylacetic acid + NADPH + Hydrogen Iondetails
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.
Gene Name:
UGT1A1
Uniprot ID:

Gene Name:

Uniprot ID:
P48448
Molecular weight:

Reactions
4-Hydroxyphenylacetaldehyde + NAD + Water → p-Hydroxyphenylacetic acid + NADH + Hydrogen Iondetails
4-Hydroxyphenylacetaldehyde + NADP + Water → p-Hydroxyphenylacetic acid + NADPH + Hydrogen Iondetails
General function:
Involved in oxidoreductase activity
Specific function:
Oxidizes medium and long chain saturated and unsaturated aldehydes. Metabolizes also benzaldehyde. Low activity towards acetaldehyde and 3,4-dihydroxyphenylacetaldehyde. May not metabolize short chain aldehydes. May use both NADP(+) and NAD(+) as cofactors. May have a protective role against the cytotoxicity induced by lipid peroxidation.
Gene Name:
ALDH3B1

General function:
sulfotransferase activity
Specific function:
Sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the sulfate conjugation of phenolic monoamines (neurotransmitters such as dopamine, norepinephrine and serotonin) and phenolic and catechol drugs.
Gene Name:
