3,4-Dihydroxyphenylacetaldehyde (DOPAL), also known as dopamine aldehyde, is a metabolite of the monoamine neurotransmitter dopamine formed by monoamine oxidase (MAO). [ 2 ] [ 3 ] Other metabolic pathways of dopamine metabolism include methylation by catechol O -methyltransferase (COMT) into 3-methoxytyramine and β-hydroxylation by dopamine β ...

3,4-Dihydroxyphenylacetic acid (DOPAC) is a metabolite of the neurotransmitter dopamine.Dopamine can be metabolized into one of three substances. One such substance is DOPAC.
Phenylacetaldehyde is an organic compound used in the synthesis of fragrances and polymers. [1] Phenylacetaldehyde is an aldehyde that consists of acetaldehyde bearing a phenyl substituent; the parent member of the phenylacetaldehyde class of compounds.
Chemical structure of DOPAL.. The catecholaldehyde hypothesis is a scientific theory positing that neurotoxic aldehyde metabolites of the catecholamine neurotransmitters dopamine and norepinephrine are responsible for neurodegenerative diseases involving loss of catecholaminergic neurons, for instance Parkinson's disease.
The endogenously produced autotoxin metabolite of dopamine, 3,4-Dihydroxyphenylacetaldehyde (DOPAL), is a potent inducer of programmed cell death (apoptosis) in dopaminergic neurons. [8] DOPAL may play an important role in the pathology of Parkinson's disease .

l-DOPA is produced from the amino acid l-tyrosine by the enzyme tyrosine hydroxylase. l-DOPA can act as an l-tyrosine mimetic and be incorporated into proteins by mammalian cells in place of l-tyrosine, generating protease-resistant and aggregate-prone proteins in vitro and may contribute to neurotoxicity with chronic l-DOPA administration.
