fosfoanhydridebinding
Fosfoanhydridebinding, or phosphoanhydride bond, is a covalent linkage between two phosphate groups (P–O–P) formed by a condensation reaction that releases water. This type of bond is common in biological energy carriers, most notably in adenosine triphosphate (ATP), adenosine diphosphate (ADP), and inorganic pyrophosphate (PPi). In molecules such as ATP, there are two phosphoanhydride bonds: one linking the alpha and beta phosphates and another linking the beta and gamma phosphates.
Phosphoanhydride bonds are formed through dehydration synthesis between phosphate units. They are often described as high-energy
Biological significance and context
Phosphoanhydride bonds are central to metabolism because they enable rapid energy transfer. The two bonds in
