THREE-uh-neen

Definition

An essential amino acid that is a vital building block of proteins and serves as a key site for chemical modification in biological signaling processes.

Etymology

The word was coined in 1935 by American biochemist William Cumming Rose, who derived it from 'threose'—a four-carbon sugar—because the acid's structure resembles that of the sugar.

In the news

In the article, threonine is identified as the specific amino acid residue on the Tau protein that undergoes phosphorylation, creating a diagnostic marker. Precise targeting of this site is crucial for developing accurate biochemical assays.
