I-D-Serine (HD-Ser-OH) (CAS: 312-84-5) iwuhlobo lwe-D lwe-amino acid serine, kodwa ayisetshenziselwa ukuhlanganiswa kwamaprotheni.Ama-amino acid aphakathi kwama-molecule abaluleke kakhulu emvelweni futhi akhona ku-l- no-d-form.Izakhiwo zamakhemikhali nezomzimba ze-l- kanye ne-d-amino acid zifana kakhulu ngaphandle kwezimpawu zazo zokubona[1].Ngesikhathi sokuvela kokuphila, ama-l-amino acid kuphela akhethiwe ukuze kwakhiwe ama-polypeptides namaprotheni.
Ama-amino acid kanye ne-derivatives, asetshenziswa ekuhlanganiseni kwe-peptide, asetshenziswa njenge-organic synthesis intermediate, pharmaceutical intermediate, angasetshenziswa njenge-chiral intermediate, reagent biochemical noma i-chemical reagent.
I-D-Serine ibandakanyeka ku-biosynthesis ye-purines, i-pyrimidines, namanye ama-amino acid.I-D-Serine futhi iyi-agonist yesayithi ye-glycine ye-NMDA-type glutamate receptor.Isebenza futhi njenge-Lacosamide emaphakathi.
Indlela yokukhiqiza i-DL-serine ne-chloroacetyl chloride isetshenziswa njengezinto ezingavuthiwe ngaphansi kwezimo ze-alkaline, zihwamuke ukuze zome ngaphansi kwengcindezi encishisiwe, zikhishwe nge-ethyl acetate, futhi umkhiqizo utholakala ngemva kokwelashwa ngekhabhoni ecushiwe nokuxazululwa nge-acylase I.
