Acetic acid derivatives of the heterocyclic compound indole. (Merck Index, 11th ed)
Skatole, also known as 3-methylindole, is a foul-smelling, crystalline compound that is a natural product of bacterial breakdown in the intestines and can be found in some plants, contributing to the characteristic odor of feces and certain flowers like jasmine.
Hydroxyindoleacetic acid (5HIAA) is a major metabolite of serotonin, a neurotransmitter, formed by the action of monoamine oxidase and aldehyde dehydrogenase, and its measurement in urine is often used as a biomarker for serotonin synthesis in clinical and research settings.
Decarboxylated monoamine derivatives of TRYPTOPHAN.
Any of the hormones produced naturally in plants and active in controlling growth and other functions. There are three primary classes: auxins, cytokinins, and gibberellins.
An enzyme that catalyzes the hydroxylation of TRYPTOPHAN to 5-HYDROXYTRYPTOPHAN in the presence of NADPH and molecular oxygen. It is important in the biosynthesis of SEROTONIN.
A genus of gram-negative, aerobic, rod-shaped bacteria widely distributed in nature. Some species are pathogenic for humans, animals, and plants.
An essential amino acid that is necessary for normal growth in infants and for NITROGEN balance in adults. It is a precursor of INDOLE ALKALOIDS in plants. It is a precursor of SEROTONIN (hence its use as an antidepressant and sleep aid). It can be a precursor to NIACIN, albeit inefficiently, in mammals.
The usually underground portions of a plant that serve as support, store food, and through which water and mineral nutrients enter the plant. (From American Heritage Dictionary, 1982; Concise Dictionary of Biology, 1990)
