# Finally, dephospho-CoA is phosphorylated using ATP to coenzyme A by the enzyme [[dephosphocoenzyme A kinase]].
Since coenzyme A is chemically a [[thiol]], it can react with [[carboxylic acid]]s to form [[thioesters]], thus functioning as an [[acyl]] group carrier. A molecule of coenzyme A carrying an [[acetyl]] group is also referred to as '''[[acetyl-CoA]]'''. When it is not attached to an acyl group it is usually referred to as 'CoASH' or 'HSCoA'.
