Intshayelelo
I-D-tert-leucine (i-D-tert-leucine) i-organic compound kunye ne-chemical formula C7H15NO2 kunye ne-molecular weight ye-145.20g / mol. Yimolekyuli ye-chiral, kukho ii-stereoisomers ezimbini, i-D-tert-leucine yenye yazo. Ubume be-D-tert-leucine buhamba ngolu hlobo lulandelayo:
1. Imbonakalo: I-D-tert-leucine yikristale engenambala okanye i-white crystalline powder.
2. Ukunyibilika: kunokunyibilika kancinane emanzini, ukunyibilika kancinane kwi-ethanol nakwizinyibilikisi ze-Etere.
3. Indawo yokunyibilika: Indawo yokunyibilika ye-D-tert-leucine imalunga ne-141-144°C.
I-D-tert-leucine isetyenziswa ikakhulu kwi-Chiral synthesis kwi-organic synthesis kunye nokuveliswa kwamayeza. Inezicelo ezibalulekileyo kwi-Enantioselective Catalytic Reactions kunye nophando lweziyobisi. Ukusetyenziswa ngokuthe ngqo kolu hlobo lulandelayo:
1. I-Chiral synthesis: I-D-tert-leucine ingasetyenziselwa i-chiral catalysts okanye i-Chiral reagents yokudibanisa i-chiral compounds.
2. Ukwenziwa kweziyobisi: I-D-tert-leucine isetyenziswa kakhulu kuphando lweziyobisi kunye nokuhlanganiswa kweziyobisi, ukudibanisa iimolekyuli zamachiza e-chiral.
Indlela yokulungiselela i-D-tert-leucine ikakhulu ngokudibanisa imichiza okanye ukuvutshelwa. Indlela yokudityaniswa kwemichiza ngokuqhelekileyo luchungechunge lokusabela kwemathiriyeli ekrwada yokwenziwa ukufumana imveliso ekujoliswe kuyo. Ukuvubela kukusetyenziswa kweemicroorganisms (ezifana ne-Escherichia coli) ukugaya i-substrates ezithile ukuvelisa i-D-tert-leucine.
Ngokumalunga nolwazi lokhuseleko, ubutyhefu be-D-tert-leucine buphantsi, kwaye kukholelwa ngokubanzi ukuba akukho bungozi bucacileyo kumzimba womntu. Nangona kunjalo, kufuneka uqaphele ukhuseleko lomntu ngexesha lokusebenza, ugweme ukudibanisa ngqo nolusu kunye namehlo, kwaye ugcine iimeko ezifanelekileyo zomoya. Landela iinkqubo zokusebenza ezikhuselekileyo ngexesha lokusetyenziswa, kwaye uthathe amanyathelo afanelekileyo okukhusela ngokusekelwe kubuninzi kunye nogxininiso olusetyenzisiweyo. Kwimeko yokudibana ngengozi okanye ukuginya, nceda ufune unyango kwangethuba kwaye uthathe ulwazi oluhambelana nokhuseleko olusesibhedlele.
