Mawu Oyamba
D-tert-leucine (D-tert-leucine) ndi organic pawiri ndi mankhwala chilinganizo C7H15NO2 ndi molecular kulemera kwa 145.20g/mol. Ndi molekyulu ya chiral, pali ma stereoisomers awiri, D-tert-leucine ndi amodzi mwa iwo. Chikhalidwe cha D-tert-leucine ndi motere:
1. Maonekedwe: D-tert-leucine ndi kristalo wopanda mtundu kapena ufa woyera wa crystalline.
2. Kusungunuka: kumatha kusungunuka pang'ono m'madzi, kusungunuka pang'ono mu ethanol ndi zosungunulira za Etere.
3. Malo osungunuka: Malo osungunuka a D-tert-leucine ndi pafupifupi 141-144°C.
D-tert-leucine amagwiritsidwa ntchito makamaka popanga Chiral synthesis mu organic synthesis ndi kupanga mankhwala. Ili ndi zofunikira mu Enantioselective Catalytic Reactions ndi kafukufuku wamankhwala. Zogwiritsidwa ntchito mwapadera ndi izi:
1. Chiral kaphatikizidwe: D-tert-leucine angagwiritsidwe ntchito ngati chiral catalysts kapena Chiral reagents kwa kaphatikizidwe mankhwala chiral.
2. Kupanga mankhwala: D-tert-leucine imagwiritsidwa ntchito kwambiri pofufuza za mankhwala ndi kaphatikizidwe ka mankhwala, popanga mamolekyu a chiral mankhwala.
Njira yokonzekera D-tert-leucine ndi makamaka kudzera mu kaphatikizidwe ka mankhwala kapena nayonso mphamvu. Njira yophatikizira mankhwala nthawi zambiri imakhala njira yopangira zinthu zopangira kuti mupeze zomwe mukufuna. Fermentation ndi kugwiritsa ntchito tizilombo toyambitsa matenda (monga Escherichia coli) kuti tigayitse magawo enaake kuti apange D-tert-leucine.
Ponena za chitetezo, kawopsedwe wa D-tert-leucine ndi wotsika, ndipo amakhulupirira kuti palibe vuto lililonse mthupi la munthu. Komabe, muyenera kusamala zachitetezo chaumwini mukamagwira ntchito, pewani kukhudzana mwachindunji ndi khungu ndi maso, komanso kukhala ndi mpweya wabwino. Tsatirani njira zotetezeka zogwirira ntchito mukamagwiritsa ntchito, ndipo tsatirani njira zodzitetezera potengera kuchuluka kwake komanso kuchuluka komwe kwagwiritsidwa ntchito. Mukakumana mwangozi kapena kumwa, chonde pitani kuchipatala munthawi yake ndikupita nazo kuchipatala.
