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.
It is a major constituent of the molecule phosphate, which is instrumental in the storage of energy as adenosine triphosphate (ATP) molecules. Phosphorus is an essential compound of RNA and DNA, and is a part of the molecular structure of phospholipids, the key components in the structure of cell membranes.he energy released from the high energy phosphate bond of ATP is essential for the operation of the sodium/potassium pump, which exchanges three sodium ions for two potassium ions across a biological membrane.
