D-Serine (HD-Ser-OH) (CAS: 312-84-5) yog D-daim ntawv ntawm cov amino acid serine, tab sis tsis yog siv rau cov protein synthesis.Amino acids yog cov molecules tseem ceeb tshaj plaws nyob rau hauv cov xwm thiab muaj nyob rau hauv ib tug l- thiab d-daim ntawv.Cov khoom siv tshuaj thiab lub cev ntawm l- thiab d-amino acids zoo sib xws tshwj tsis yog rau lawv cov yam ntxwv kho qhov muag[1].Thaum lub sij hawm tshwm sim ntawm lub neej, tsuas yog cov l-amino acids raug xaiv rau kev tsim ntawm polypeptides thiab cov proteins.
Amino acids thiab derivatives, siv nyob rau hauv peptide synthesis, siv raws li ib tug organic synthesis intermediate, tshuaj intermediate, yuav siv tau raws li ib tug chiral intermediate, biochemical reagent los yog tshuaj reagent.
D-Serine koom nrog hauv biosynthesis ntawm purines, pyrimidines, thiab lwm yam amino acids.D-Serine kuj yog ib qho agonist ntawm glycine site ntawm NMDA-type glutamate receptor.Nws kuj ua raws li Lacosamide nruab nrab.
Cov txheej txheem ntau lawm DL-serine thiab chloroacetyl chloride yog siv los ua raw cov ntaub ntawv nyob rau hauv alkaline tej yam kev mob, evaporated kom qhuav nyob rau hauv txo siab, muab rho tawm nrog ethyl acetate, thiab cov khoom yog tau tom qab kev kho mob nrog activated carbon thiab daws nrog acylase I.
