Metabolite Identification
Common NameTrichloroacetic acid
DescriptionTrichloroacetic acid, also known as trichloroacetate or TCA, belongs to the class of organic compounds known as alpha-halocarboxylic acids. These are carboxylic acids containing a halogen atom bonded to the alpha carbon atom. Trichloroacetic acid is a drug. Trichloroacetic acid is a moderately acidic compound (based on its pKa). Trichloroacetic acid exists in all living organisms, ranging from bacteria to humans. A monocarboxylic acid that is acetic acid in which all three methyl hydrogens are substituted by chlorine. Trichloroacetic acid is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound.

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
Chloral hydrate + NAD → Trichloroacetic acid + NADH + 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).

Reactions
Chloral hydrate + NAD → Trichloroacetic acid + NADH + 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.
