Phosphoryl Transfer

Phosphoryl Transfer. In biological systems, the element phosphorous almost always exists as phosphate. Phosphorous is stable in several different oxidation states, but in phosphate, the oxidation state is +5. Therefore, the phosphorous atom in phosphate will always behave as an electrophile.
