Isicelo:

I-D-Valine (i-HD-Val-OH) (i-CAS: i-640-68-6) i-D-ifomu ye-valine, i-isomer ye-non-proteinogenic ye-valine.I-D-Valine ngumthombo obalulekileyo we-organic chiral, osetyenziswa kakhulu kwiziyobisi ze-chiral, izongezo ze-chiral, izongezo ze-chiral kunye nezinye iinkalo.Njenge-asidi ephilayo esebenzayo, i-D-Valine idlala indima engenakuphinda ithathelwe indawo kwi-asymmetric synthesis yezinye iikhompawundi ze-chiral, okwangoku ingakumbi kwimveliso ye-antibiotics entsha ebanzi, i-D-Valerian ammonia alcohol, inkqubo ye-peptide synthesis ye-agent ekhuselayo ye-Valine.Isetyenziswa njengezinto ezikrwada zamayeza kunye nabaphakathi bamayeza, kwaye ikwasetyenziswa ekudibaneni kwe-Alatan yesiswiti.Isetyenziswe njenge-inhibitor ekhethiweyo yokwanda kweeseli kwinkcubeko yeeseli ukuvimbela iiseli ezingenayo i-dextrorotatory amino acid oxidase.I-D-Valine ingasetyenziselwa uphando lwe-biochemical.I-D-Valine yi-intermediate ye-fluvalinate.I-D-Valine ikwayimathiriyeli ekrwada ebalulekileyo njengamachiza e-chiral ngokomzekelo ingasetyenziselwa ukuhlanganiswa kweziyobisi ze-antineoplastic, anti-diabetes kunye neziyobisi ezinengxaki.Ngokwandiswa kweenkalo zezicelo kunye nokufunwa kweemarike ze-D-Valine, ukulungiswa kwe-D-Valine kuya kuba yintsimi yophando eshushu kwi-amino acid.
