Threonine (symbol Thr or T) is an amino acid that is used in the biosynthesis of proteins It contains an α-amino group (which is in the protonated −NH + 3 form under biological conditions) a carboxyl group (which is in the deprotonated −COO − form under biological conditions) and a side chain containing a hydroxyl group making it a polar uncharged amino acid

Threonine (afgekort als Thr of T) is een hydrofiel aminozuur Het is een van de twintig natuurlijk voorkomende α-aminozuren die voor eiwitsynthese wordt gebruikt De zijketen van threonine bevat een polaire hydroxylgroep dat interacties aan kan gaan met andere moleculen In eiwitten speelt threonine een belangrijke rol bij de totstandkoming van de secundaire structuur en bij deelname aan

The kinetics of the reaction of the amino acid epimers L ‐isoleucine D ‐alloisoleucine L ‐threonine and D ‐allo‐threonine with o ‐phthaldialdehyde and mercaptoethanol were determined at 25C L ‐Isoleucine reacts faster than its D ‐epimer whereas L ‐threonine reacts slightly slower than its D ‐epimer In the case of isoleucine the consequence can be an allo/iso ratio
