1.nounC2
Definition

the chemical process in which a phosphate group is put onto a molecule, either from free phosphate or from another organic molecule that already carries one

Example

In the lab dish, phosphorylation switched the repair protein on within seconds.

phosphorylation can switch a protein on

After insulin arrived, phosphorylation changed how the liver cell used sugar.

phosphorylation in cell signaling

Common collocations
  • protein phosphorylation
  • abnormal phosphorylation
  • phosphorylation of glucose
  • block phosphorylation
  • phosphorylation in cells
Synonyms
  • phosphate addition

    a plain explanatory phrase rather than the standard technical term

  • phosphate transfer

    narrower, because it emphasizes movement from one molecule to another

  • modification

    much broader and only works when the phosphate change is already clear from context

Antonyms

Grammar Patterns

phosphorylation of a protein

block phosphorylation

phosphorylation in cells

Usage Note

Usually uncountable. Common in biochemistry with words such as protein, enzyme, sugar, and cell signal. Distinguish from phosphate, which names the chemical group or compound itself, not the process of attaching it.

Common Mistakes

Phosphate of the protein increased after the test.
Phosphorylation of the protein increased after the test.
'phosphate' names the group or compound; 'phosphorylation' names the process.
The sample showed many phosphorylations after heating.
The sample showed a high level of phosphorylation after heating.
When you mean the process in general, this word is usually uncountable.

Synonym discussion

Sense: noun/1

Phosphorylation is the standard biochemistry term for adding a phosphate group to a molecule. Phosphate addition can explain the idea in plainer English, but it is not the usual technical label in papers or textbooks. Phosphate transfer is narrower: it fits cases where the phosphate moves from one molecule to another, but it does not cover every way the process can happen. Modification is much broader and only tells you that something changed, not what was added. Use phosphorylation when precision matters: Researchers measured phosphorylation of the protein after the signal. Use modification only when the exact chemical change is not the main point.

Etymology

GreekEnglish

Phosphorylation is a modern scientific word formed in English from phosphorylate and the noun ending -ion. The earlier part goes back to phosphorus, a name built from Greek parts meaning 'light-bearer', and the word was later shaped in chemistry for the process of adding a phosphate group.
