Description3-Oxohexacosyl-CoA, also known as 3-ketocerotoyl-CoA, belongs to the class of organic compounds known as very-long-chain 3-oxoacyl coas. These are organic compounds containing a coenzyme A derivative, which is 3-oxo acylated long aliphatic chain of 22 carbon atoms or more. Thus, 3-oxohexacosyl-CoA is considered to be a fatty ester lipid molecule. 3-Oxohexacosyl-CoA is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
