noun, plural: dephosphorylations
The removal of a phosphate group from a compound
Dephosphorylation in living cells is a common biochemical process in which a phosphate group is removed from an organic compound through hydrolysis. An example of this is when an ATP loses a phosphate group, thus changing into ADP.
Dephosphorylation can be reversed through phosphorylation in which a phosphate group is added to an organic compound (i.e. phosphate group added to ADP, becoming ATP).
