Phosphorylation

Part of speech: noun

Definitions

1. The modification process entails the incorporation of a phosphate group into a molecule, most often a protein, thereby influencing its functional activity and interactions within the cell
2. This biochemical reaction involves the attachment of a phosphate group to specific organic molecules, particularly proteins, which subsequently alters their functional properties and roles in biological systems
3. This biological modification refers to the addition of a phosphate group to organic molecules like proteins, which significantly alters their activity and cellular roles

Etymology: Phosphorylation takes its first half from "phosphor", a word that goes back to the Greek "phōsphoros", meaning "light-bearer", the name of the morning star. The element phosphorus was named for its tendency to glow in the dark, so the chain of meaning runs from a glowing substance to a chemical process that moves energy around living cells. The middle piece, "phosphoryl", is a chemist's coinage built from "phosphor" plus "-yl", the suffix used for radical groups in organic chemistry. The final "-ation" is a familiar suffix that turns an action into a noun. It arrived in English through Old French from Latin "-ātiō", so the whole word is a modern compound assembled from older parts: a glowing element, a chemical group, and a process ending.
