Phosphorylation

Definition
noun, plural: phosphorylations
The transferring of phosphoryl group from a donor to the recipient molecule

Phosphorylation is important in living cells since it is through this that energy-rich molecules (e.g. ATPs) are formed. For instance, a phosphoryl group (phosphate) is added to ADP, thus forming ATP, usually catalysed by phosphorylases and kinases.
