The chemical reactions and pathways involving 2-oxobutyrate, the anion of the organic acid 2-oxobutyric acid, which contains a ketone group on carbon 2.

The chemical reactions and pathways resulting in the breakdown of phenylethylamine, an amine with pharmacological properties similar to those of amphetamine, occurs naturally as a neurotransmitter in the brain, and is present in chocolate and oil of bitter almonds.

The chemical reactions and pathways occurring at the level of individual cells resulting in the breakdown of biogenic amines, any of a group of naturally occurring, biologically active amines, such as norepinephrine, histamine, and serotonin, many of which act as neurotransmitters.

The chemical reactions and pathways involving phenylethylamine, an amine with pharmacological properties similar to those of amphetamine, occurs naturally as a neurotransmitter in the brain, and is present in chocolate and oil of bitter almonds.

The chemical reactions and pathways resulting in the breakdown of nicotine, (S)(-)-3-(1-methyl-2-pyrrolidinyl)pyridine.

The chemical reactions and pathways resulting in the breakdown of substances, including the breakdown of carbon compounds with the liberation of energy for use by the cell or organism.

The chemical reactions and pathways involving nicotine, (S)(-)-3-(1-methyl-2-pyrrolidinyl)pyridine.

The chemical reactions and pathways resulting in the breakdown of 3-hydroxyphenylacetate, 1,3-benzenediol monoacetate, also known as resorcinol monoacetate.

The chemical reactions and pathways resulting in the breakdown of a phenol, any compound containing one or more hydroxyl groups directly attached to an aromatic carbon ring.

The chemical reactions and pathways involving 4-toluenecarboxylate, 4-methylbenzenecarboxylate, the anion of carboxylic acid attached to a methylbenzene molecule.

The chemical reactions and pathways involving benzene, C6H6, a volatile, very inflammable liquid, contained in the naphtha produced by the destructive distillation of coal, from which it is separated by fractional distillation, or any of its derivatives.

The chemical reactions and pathways resulting in the breakdown of 4-toluenecarboxylate, 4-methylbenzenecarboxylate, the anion of carboxylic acid attached to a methylbenzene molecule.

The chemical reactions and pathways resulting in the breakdown of aromatic compounds, any substance containing an aromatic carbon ring.

The chemical reactions and pathways resulting in the breakdown of catechol-containing compounds. Catechol is a compound containing a pyrocatechol nucleus or substituent.

The chemical reactions and pathways resulting in the breakdown of catechol via the ortho-cleavage pathway, in which the catechol aromatic ring is broken between the two carbon atoms bearing hydroxyl groups.

A pathway of aromatic compound degradation by ortho-cleavage; one branch converts protocatechuate, derived from phenolic compounds, to beta-ketoadipate, and the other branch converts catechol, generated from various aromatic hydrocarbons, amino aromatics, and lignin monomers, also to beta-ketoadipate. Two additional steps accomplish the conversion of beta-ketoadipate to tricarboxylic acid cycle intermediates.

The chemical reactions and pathways resulting in the breakdown of catechol via the meta-cleavage pathway, in which the catechol aromatic ring is broken between a hydroxylated carbon atom and an adjacent unsubstituted carbon atom.

The chemical reactions and pathways resulting in the breakdown of protocatechuate, the anion of 3,4-dihydroxybenzoic acid, to yield oxaloacetate and pyruvate.
