Phosphorylation of proteins induces new properties
Phosphoproteins are formed when a phosphate group is esterified to an -OH group of a Ser, Thr, or Tyr side chain. A typical cellular pH values, this phosphate group bears two negative charges -PO32-. Compare this side-chain modification to the 20 side chains of the common amino acids found in proteins and comment on the novel properties that it introduces into side-chain possibilities.
