The bond between CH2 and P of phosphate through O is called phosphoester bond. Only one such bond is present in both AMP and ADP.Link of phosphate groups through O by elimination of water molecule is called phosphoanhydride bond.In AMP, only single phosphate group present so no phosphoanhydride bond is present. But inADP, two phosphate groups are linked by one phospoanhydride bond.AMP 1 0ADP 1 1
