Metabolite Identification
Common NameIndoleacetaldehyde
DescriptionIndoleacetaldehyde, also known as tryptaldehyde, belongs to the class of organic compounds known as 3-alkylindoles. 3-Alkylindoles are compounds containing an indole moiety that carries an alkyl chain at the 3-position. Indoleacetaldehyde is an extremely weak basic (essentially neutral) compound (based on its pKa). Indoleacetaldehyde exists in all living species, ranging from bacteria to humans. Within humans, indoleacetaldehyde participates in a number of enzymatic reactions. In particular, indoleacetaldehyde can be biosynthesized from tryptamine; which is mediated by the enzyme kynurenine 3-monooxygenase. In addition, indoleacetaldehyde can be converted into indoleacetic acid; which is catalyzed by the enzyme aldehyde dehydrogenase, mitochondrial. In humans, indoleacetaldehyde is involved in tryptophan metabolism. Outside of the human body, indoleacetaldehyde has been detected, but not quantified in, several different foods, such as nuts, turmerics, Alaska blueberries, summer savouries, and black raspberries. This could make indoleacetaldehyde a potential biomarker for the consumption of these foods. Indoleacetaldehyde is also a substrate for amine oxidase and 4-trimethylaminobutyraldehyde dehydrogenase.

4. Alpha-aminoadipic semialdehyde dehydrogenase
General function:
Involved in oxidoreductase activity
Specific function:
Multifunctional enzyme mediating important protective effects. Metabolizes betaine aldehyde to betaine, an important cellular osmolyte and methyl donor. Protects cells from oxidative stress by metabolizing a number of lipid peroxidation-derived aldehydes. Involved in lysine catabolism.

5. Aldehyde dehydrogenase family 1 member A3
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).

9. Amiloride-sensitive amine oxidase [copper-containing]
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.
