Phosphate group: A functional group characterized by a phosphorus atom bonded to four oxygen atoms (three single bonds and one double bond). One of these oxygen atoms must be bonded to another atom; if not, the structure is a phosphate ion. Generic phosphate group molecular structure.
The two phosphate groups of ADP are added in series to the 5â carbon of the sugar backbone, while the adenosine molecule attaches to the 1â carbon. The two phosphates in ADP can be correlated with ATP and AMP. ATP consists of three phosphate groups attached in series to the 5â carbon location, whereas ADP contains two phosphate groups attached to the 5â position, and AMP contains only one phosphate group attached at the 5â position.
