Lauroyl-coenzyme A can function as an acyl group carrier, acetyl-CoA. It can be used as an intermediate in lipid metabolism and is involved in lipid biosynthesis and fatty acid transport.
Myristoyl coenzyme A (myristoyl-CoA) is a derivative of CoA that contains the long-chain fatty acid myristic acid . It is a substrate for N-myristoyltransferase during myristoylation, a process that adds a myristoyl group to proteins either during translation to modify protein activity or post-translationally in apoptotic cells. It is also a substrate in the de novo synthesis of phosphatidylinositol .
Coenzyme Q10 is a component of the electron transport chain and participates in aerobic cellular respiration, generating energy in the form of ATP. In its reduced form, it acts as an antioxidant. Coenzyme Q2 is a precursor of coenzyme Q10 that has 2, rather than 10, isoprenoid units on the ubiquinone base. It can act as an electron acceptor for bacterial Complex I. In mammalian cells, exogenous coenzyme Q2 prevents the production of reactive oxygen species associated with Complex I activity. Forms of coenzyme Q with shorter isoprenoid chains, including coenzyme Q2, induce p53-dependent apoptosis in human B-cell acute lymphoblastoid leukemia BALL-1 cells.
Isobutyryl coenzyme A (isobutyryl-CoA) is a short-chain branched acyl CoA. Isobutyryl-CoA is a substrate for isobutyryl-CoA dehydrogenase (IBDH) in the catabolism of valine and an intermediate in the synthesis of isobutyryl-L-carnitine , which accumulates in IBDH deficiency.
Ethylmalonyl coenzyme A (CoA) is a key intermediate in the ethylmalonyl-CoA pathway for carbon metabolism in certain bacteria, such asM. extorquens, which uses this pathway when grown on ethylamine.1,2It is produced from crotonyl-CoA by crotonyl-CoA reductase/carboxylase and modified by ethylmalonyl-CoA mutase to make methylsuccinyl-CoA. 1.Good, N.M., Martinez-Gomez, N.C., Beck, D.A.C., et al.Ethylmalonyl coenzyme A mutase operates as a metabolic control point in Methylobacterium extorquens AM1J.

Methylmalonyl coenzyme A (methylmalonyl-CoA) is an intermediate in multiple metabolic pathways in bacteria and eukaryotes.1,2,3It is an intermediate in carbon assimilation in certain bacteria and carbon fixation in plants.1,2Methylmalonyl-CoA is converted to succinyl-CoA by methylmalonyl-CoA mutase with vitamin B12as a coenzyme.3A deficiency in vitamin B12leads to a build-up of methylmalonyl-CoA.4 1.Anthony, C.How half a century of research was required to understand bacterial growth on C1 and C2 compounds; the story of the serine cycle and the ethylmalonyl-CoA pathwaySci.

Succinyl-Coenzyme A sodium salt(Succinyl-CoA sodium salt) 参与柠檬酸循环,在柠檬酸循环中转化为琥珀酸。Succinyl-Coenzyme A (sodium salt) 在生物体内参与多种代谢反应,在体内有着举足轻重的作用 Succinyl-Coenzyme A sodium salt 参与血红素的合成,可用于研究由营养性维生素 B12 缺乏症 (致使 Succinyl-Coenzyme A 合成缺乏) 所引起的代谢疾病、神经疾病和血液学异常导致的疾病。
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. CHC is converted to CHCoA by a succinyl-CoA CHC CoA transferase, and CHCoA is then degraded by a dehydrogenase. CHCoA is converted to hippuric acid in submitochondrial fractions isolated from guinea pig liver.
