Phenolic human metabolites

Gentisic acid is a dihydroxybenzoic acid.

Homovanillic acid (HOC6H3(OCH3)CH2COOH; synonyms: 3-methoxy-4-hydroxyphenyl acetic acid; HVA; 4-hydroxy-3-methoxy-benzeneacetic acid; 4-hydroxy-3-methoxyphenylacetic acid) is a major catecholamine metabolite and is produced by the consecutive action of monoamine oxidase and catechol-O-methyl transferase on dopamine.

Dihydroxyphenylethylene glycol (DOPEG) is a metabolite of norepinephrine through monoamine oxidase.

3,4-Dihydroxymandelic acid (DHMA, DOMA) is a metabolite of norepinephrine.

3,4-Dihydroxyphenylacetic acid (DOPAC) is a metabolite of the neurotransmitter dopamine.

3,4-Dihydroxyphenylacetaldehyde (DOPAL) is a metabolite of the neurotransmitter dopamine.

4-Hydroxybenzoic acid, also known as p-hydroxybenzoic acid (PHBA), is a monohydroxybenzoic acid, a phenolic derivative of benzoic acid.

Vanillylmandelic acid (VMA) is a chemical intermediate in the synthesis of artificial vanilla flavorings and is an end-stage metabolite of the catecholamines, epinephrine, and norepinephrine.

Urolithin A is a urolithin, a type of microflora human metabolite of dietary ellagic acid derivatives, such as ellagitannins.

3,5-Dihydroxyphenylpropionoic acid is a metabolite of alkylresorcinols, first identified in human urine and can be quantified in urine and plasma, and may be an alternative, equivalent biomarker of whole grain wheat intake.

trans-Resveratrol-3-O-glucuronide is a metabolite of resveratrol and trans-resveratrol-3-O-glucoside (piceid).

3-Methoxy-4-hydroxyphenylglycol (MHPG, MOPEG) is a metabolite of norepinephrine degradation.

2,3-Dihydroxycinnamic acid is a hydroxycinnamic acid.

3,5-Dihydroxycinnamic acid is a hydroxycinnamic acid.

1-Hydroxyphenanthrene is a phenanthrol and a human metabolite of phenanthrene that can be detected in urine of persons exposed to PAHs.

Urolithin B is an urolithin, a type of phenolic compounds produced in the human gut after absorption of ellagitannins-containing food such as pomegranate, strawberries, red raspberries, walnuts or oak-aged red wine.

3,5-Dihydroxybenzoic acid (α-resorcylic acid) is a dihydroxybenzoic acid.
