===Other macroergic compounds===
*'''Other nucleoside triphosphates''' are less versatile and are used for specific purposes. E.g. [[UTP]] serves to activate carbohydrates for their entry into metabolic pathways.
*'''Enol phosphates''' contain a &minus; OH group, which is esterically bound to the phosphate. The most important representative, phosphoenolpyruvate (PEP), is a macroergic compound with the highest energy potential ΔG (up to &minus; 61.9 kJ/mol). Therefore, the reaction of converting PEP to pyruvate is also an irreversible reaction of glycolysis.
*'''Acyl phosphates''' contain an anhydride bond &minus;COOH with phosphate. These include carbamoyl phosphate (used in the synthesis of urea) or 1,3-bisphosphoglycerate (an intermediate of glycolysis).
*Other macroergic compounds include '''guanidine phosphates'''' (eg [[creatine phosphate]]) or '''thioesters and thioethers''' (HS-CoA derivatives, SAM). Sometimes we can come across the term ''low-energy phosphates.'' Low-energy phosphates include, for example, glucose-6-phosphate and release less energy, between 9 and 20 kJ/mol.
