1. Ponahalo: D-tert-leucine ke kristale e se nang mebala kapa phofo e tšoeu ea kristale.
2. Sollubility: e ka qhibiliha hanyenyane ka metsing, e qhibiliha hanyenyane ka har'a lihlapolli tsa ethanol le Ether.
3. Sebaka se qhibilihang: Sebaka se qhibilihang sa D-tert-leucine se ka bang 141-144°C.
D-tert-leucine e sebelisoa haholo-holo bakeng sa Chiral synthesis ho organic synthesis le tlhahiso ea meriana. E na le lits'ebetso tsa bohlokoa ho Enantioselective Catalytic Reactions le lipatlisiso tsa lithethefatsi. Lisebelisoa tse khethehileng ke tse latelang:
1. Chiral synthesis: D-tert-leucine e ka sebelisoa e le li-catalysts tsa chiral kapa li-reagents tsa Chiral bakeng sa motsoako oa metsoako ea chiral.
2. Ho hlahisa lithethefatsi: D-tert-leucine e sebelisoa haholo lipatlisisong tsa lithethefatsi le motsoako oa lithethefatsi, bakeng sa motsoako oa limolek'hule tsa lithethefatsi tsa chiral.
Mokhoa oa ho lokisa D-tert-leucine haholo-holo ka ho kopanya lik'hemik'hale kapa ho belisoa. Mokhoa oa ho kopanya lik'hemik'hale hangata ke letoto la karabelo ea lisebelisoa tse tala tsa maiketsetso ho fumana sehlahisoa se lebisitsoeng. Ho belisoa ke tšebeliso ea likokoana-hloko (joaloka Escherichia coli) ho fetola likaroloana tse itseng ho hlahisa D-tert-leucine.
Mabapi le tlhahisoleseling ea polokeho, chefo ea D-tert-leucine e tlase, 'me ka kakaretso ho lumeloa hore ha ho kotsi e totobetseng' meleng oa motho. Leha ho le joalo, u ntse u lokela ho ela hloko tšireletso ea botho nakong ea ts'ebetso, qoba ho kopana ka ho toba le letlalo le mahlo, 'me u boloke maemo a matle a moea.
