Octanoyl coenzyme A (octanoyl-CoA) is a medium-chain acyl CoA and a metabolic intermediate in mitochondrial fatty acid β-oxidation. Levels of octanoyl-CoA are increased in the liver of patients with Reye's syndrome and β-oxidation of octanoyl-CoA by medium-chain acyl CoA dehydrogenase (MCADH) is decreased in patients with MCADH deficiency (MCD). Octanoyl-CoA inhibits citrate synthase and glutamate dehydrogenase.

Phenylacetyl-coenzyme A (CoA) is a key intermediate in aerobic catabolism of phenylacetate in bacteria such asPseudomonas, when cultured in minimal media using phenylacetate as the sole carbon source.1It is a precursor in the synthesis of the antibiotic penicillin G found in industrial strains ofP. chrysogenum. Phenylacetyl-CoA also acts as an effector molecule of the TetR family transcriptional repressor PaaR inT. thermophilusand the GntR family transcriptional regulator PaaX inE. coliandPseudomonas, binding to each protein to induce derepression of various genes.2

Cyclohexanoyl coenzyme A (CHCoA) is an acyl CoA that contains a cyclohexane group. It is the activated form of cyclohexane carboxylic acid (CHC) in R. palustris.
