Codsiga:

D-(+)-Malic Acid (CAS: 636-61-3) loo isticmaalo sida aashitada iyo walaxda dhadhanka, cunto lagu daro.Iyo sidoo kale waxaa loo isticmaalaa meesha ay ku yar tahay citric acid ee macaanka dhanaan.

D-(+)-Malic Acid (CAS: 636-61-3) waa barkad afar-kaarboon ah oo muhiim ah.Waxaa inta badan loo adeegsadaa qaybo badan oo ay ku jiraan dawooyinka chiral, daroogooyinka chiral iyo kaaliyeyaasha chiral.Waxaa loo istcimaalay sidii barkad chiral ee isku dhafka chiral ee warshadaha dawooyinka iyo cuntada.Sida aashitada organic indhaha ee firfircoon, waa mid aan lagu beddeli karin isku-dhafka asymmetry ee xeryahooda chiral qaarkood.

isomer-ka si dabiici ah u dhaca waa qaabka L-ka kaas oo laga helay tufaaxa iyo miro iyo dhir kale oo badan.Aashitada α-amino ee la xushay ayaa reagent ka ilaalinaysa amino acids.Synthon badan oo loogu talagalay diyaarinta xeryahooda chiral oo ay ku jiraan κ-opioid agonists receptor, 1α,25-dihydroxyvitamin D3 analooga, iyo phoslactomycin B.
