# Threonine

Threonine (three-letter code Thr, one-letter code T) is a polar amino acid with a secondary hydroxyl group and two chiral centres. It is beta-branched, can be phosphorylated and glycosylated, and is protected as a tert-butyl ether during Fmoc peptide synthesis. Threonine contributes to hydrogen bonding in peptide structures.
