Isicelo:

I-D-Leucine (i-HD-Leu-OH) (i-CAS: 328-38-1) yi-D-Enantiomer yeLeucine.
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-Leucine ngumthombo obalulekileyo we-organic chiral, esetyenziswa kakhulu kwiziyobisi ze-chiral, izongezo ze-chiral, izongezo ze-chiral kunye nezinye i-cross-over.Njengeasidi esebenzayo ebonakalayo, idlala indima engenakuphinda ithathelwe indawo kwi-asymmetric synthesis yezinye iikhompawundi ze-chiral.Okwangoku, isetyenziselwa ikakhulu ukuveliswa kwe-antibiotics ebanzi, i-D-Leucine, i-agent ye-Leucine Protective.
Intshayelelo: I-Leucine yi-amino acid enokufumaneka kwiiprotheni ezininzi kwaye ithathwa njengeyimfuneko ekufunxeni iintlobo ezahlukeneyo zezondlo;ingasetyenziswa kuphando lwe-biochemical;I-Leucine ingasetyenziswa njengesongezelelo sesondlo kwaye ithandwa kakhulu ngabadlali;Ukongeza, i-leucine ingasetyenziswa njengesongezo sokutya ukunyusa incasa yokutya.
Umsebenzi we-Physiological: I-Leucine, i-Isoleucine kunye ne-Valine zonke ziyi-branched chain amino acids, ezinceda ukubuyisela izihlunu emva koqeqesho, ukulawula iswekile yegazi kunye nokubonelela ngamandla kwizicubu zomzimba.Phakathi kwabo, i-D-Leucine yeyona nto isebenzayo ye-branched-chain amino acid, kodwa umzimba womntu awukwazi ukuvelisa ngokwawo kwaye unokufumaneka kuphela ngokutya.Nangona kunjalo, akukho phantse i-D-Leucine ekutyeni okuqhelekileyo.I-D-Leucine ibonakala kakhulu kwi-peptidoglycan yebhaktiriya.umsebenzi webhayoloji i-D-Leucine inomsebenzi we-antiepileptic, ephezulu kunomsebenzi we-L-Leucine.I-D-Leucine inokuphelisa ngokusebenzayo ukuxhuzula.Kwi-vitro, i-D-Leucine inokunciphisa indawo yexesha elide, kodwa ukuhanjiswa kwe-basal synaptic akunasiphumo.ukusetyenziswa kuphando lwe-biochemical.
Indlela yokuvelisa: I-Acetyl-DL-Leucine isetyenziswe njengento eluhlaza, i-L-Leucine isuswe ngonyango lwe-acylase, emva koko imveliso engcolileyo i-hydrolyzed kwi-hydrochloric acid, kwaye imveliso ecocekileyo ifunyenwe emva kwe-crystallization kunye nokucocwa.
