Cannabis Compound Identification
Common NamePhenylacetaldehyde
DescriptionPhenylacetaldehyde, also known as alpha-tolualdehyde or 2-phenylethanal, belongs to the class of organic compounds known as phenylacetaldehydes. Phenylacetaldehydes are compounds containing a phenylacetaldehyde moiety, which consists of a phenyl group substituted at the second position by an acetalydehyde. Phenylacetaldehyde is an extremely weak basic (essentially neutral) compound (based on its pKa). Phenylacetaldehyde exists in all living species, ranging from bacteria to humans. Phenylacetaldehyde is a sweet, bitter, and clover tasting compound. Outside of the human body, Phenylacetaldehyde is found, on average, in the highest concentration within a few different foods, such as corns, beers, and white wines and in a lower concentration in safflowers, taco, and bilberries. Phenylacetaldehyde has also been detected, but not quantified in, several different foods, such as small-leaf lindens, green beans, sweet oranges, mountain yams, and common thymes. This could make phenylacetaldehyde a potential biomarker for the consumption of these foods. An aldehyde that consists of acetaldehyde bearing a methyl substituent; the parent member of the phenylacetaldehyde class of compounds. Phenylacetaldehyde is a potentially toxic compound. Phenylacetaldehyde is expected to be in Cannabis as all living plants are known to produce and metabolize it.

Enzymes

General function:
Involved in oxidoreductase activity
Specific function:
Catalyzes the oxidative deamination of biogenic and xenobiotic amines and has important functions in the metabolism of neuroactive and vasoactive amines in the central nervous system and peripheral tissues. MAOB preferentially degrades benzylamine and phenylethylamine.
Gene Name:
MAOB
Uniprot ID:
P27338
Molecular weight:
58762.475
General function:
Involved in oxidoreductase activity
Specific function:
Catalyzes the oxidative deamination of biogenic and xenobiotic amines and has important functions in the metabolism of neuroactive and vasoactive amines in the central nervous system and peripheral tissues. MAOA preferentially oxidizes biogenic amines such as 5-hydroxytryptamine (5-HT), norepinephrine and epinephrine.
Gene Name:
MAOA
Uniprot ID:
P21397
Molecular weight:
59681.27
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
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
General function:
Involved in copper ion binding
Specific function:
Catalyzes the degradation of compounds such as putrescine, histamine, spermine, and spermidine, substances involved in allergic and immune responses, cell proliferation, tissue differentiation, tumor formation, and possibly apoptosis. Placental DAO is thought to play a role in the regulation of the female reproductive function.
Gene Name:
ABP1
Uniprot ID:
P19801
Molecular weight:
85377.1
General function:
Involved in copper ion binding
Specific function:
Cell adhesion protein that participates in lymphocyte recirculation by mediating the binding of lymphocytes to peripheral lymph node vascular endothelial cells in an L-selectin-independent fashion. Has a monoamine oxidase activity. May play a role in adipogenesis.
Gene Name:
AOC3
Uniprot ID:
Q16853
Molecular weight:
84621.27
General function:
Involved in copper ion binding
Specific function:
Has a monoamine oxidase activity with substrate specificity for 2-phenylethylamine and tryptamine. May play a role in adipogenesis. May be a critical modulator of signal transmission in retina.

Gene Name:
ALDH3B2
Uniprot ID:
P48448
Molecular weight:
42623.62
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.
