I-D-Serine (i-HD-Ser-OH) (i-CAS: i-312-84-5) i-D-ifom ye-amino acid serine, kodwa ayisetyenziselwa i-protein synthesis.Ii-amino acids ziphakathi kwezona molekyuli zibalulekileyo kwindalo kwaye zikhona ku-l- kunye no-d-form.Iipropathi zekhemikhali kunye nezomzimba ze-l- kunye ne-d-amino acid zifana kakhulu ngaphandle kweempawu zazo zamehlo[1].Ngethuba lokuvela kobomi, kuphela i-l-amino acids yakhethwa ukubunjwa kwe-polypeptides kunye neeprotheni.
I-amino acids kunye ne-derivatives, esetyenziswe kwi-peptide synthesis, esetyenziswe njenge-organic synthesis intermediate, i-pharmaceutical intermediate, ingasetyenziselwa njenge-chiral intermediate, i-biochemical reagent okanye i-chemical reagent.
I-D-Serine ibandakanyeka kwi-biosynthesis ye-purines, i-pyrimidines, kunye nezinye i-amino acids.I-D-Serine nayo i-agonist yesayithi ye-glycine ye-NMDA-uhlobo lwe-glutamate receptor.Ikwasebenza njengeLacosamide ephakathi.
Indlela yokuvelisa i-DL-serine kunye ne-chloroacetyl chloride isetyenziswe njengezinto eziluhlaza phantsi kweemeko ze-alkaline, i-evaporated ukuze yome phantsi koxinzelelo oluncitshisiweyo, ikhutshwe nge-ethyl acetate, kwaye imveliso ifunyenwe emva kokunyanga nge-carbon activated kunye nesisombululo nge-acylase I.
