Isicelo:

I-D-(+)-Threonine (HD-Thr-OH) (CAS: 632-20-2) yi-D-ifom ye-Threonine, eluhlobo lwe-amino acids.Ingasetyenziselwa ukulungiswa kwe-enantiomerically pure 1,3-butanediol.Ikwasetyenziswa njengendawo ephakathi ngexesha lokulungiswa kweekhompawundi ze-chiral ezifana ne-antibiotics.I-D-Threonine sisixhobo esisebenzayo se-chiral pool reagent equlethe iziko le-stereo elongezelelweyo.Ngokomzekelo, abantu basandul 'ukuyisebenzisa njengesixhobo sokuqala sokuhlanganiswa kwe-legionaminic acid ekhuselweyo.I-D-Threonine yi-isomer engeyondalo ye-L-Threonine kwaye yaziwa ngokunqanda ukukhula kunye ne-cell wall synthesis ye-Mycobacterium smegmatis.I-D-Threonine iphinda isetyenziswe njenge-synthetic intermediate yokuveliswa kwe-antibiotics ye-chiral.Indlela yokuvelisa i-DL-Threonine isetyenziswe njengento ekrwada ukusabela nge-Chloroacetyl Chloride phantsi kweemeko ze-alkaline, emva kokugxininiswa phantsi koxinzelelo oluncitshisiweyo, imveliso ikhutshwe nge-acetone kwaye ekugqibeleni isonjululwe yi-acylase I.
