Zihlala zisetyenziselwa ukupakisha umgubo.Kuxhomekeke kwiimfuno zabathengi.Ke ngoko, sixelele ngemfuno yakho phambi kokupakisha ukuba unezicelo ezizodwa.
I-1kg ukuya kwi-25kg Ukupakisha kwangaphandle kunzima.Kwaye kunzima ukusika kunye nomonakalo.Inokukhusela iimveliso zakho ngokugqibeleleyo.
I-Cbz-N-Me-D-Ala-OH, njenge-amino acid derivative ethile, ifumana izicelo ezixhaphakileyo kwi-chemistry, biochemistry, kunye nokufunyanwa kweziyobisi.
Okokuqala, kwinkalo yekhemistri, i-Cbz-N-Me-D-Ala-OH ihlala isetyenziswa njengento ekrwada okanye ephakathi kwi-organic synthesis.Iqela elikhuselayo le-Cbz (carbobenzyloxy) lizinzisa iqela le-amino ngexesha lokuphendula, liququzelela ukuguqulwa kweekhemikhali ezilandelayo ezifana ne-peptide synthesis okanye ukuguqulwa kweqela elisebenzayo.Phantsi kweemeko ezithile zokusabela, iqela elikhuselayo le-Cbz linokususwa ngokufanelekileyo ukuze liveze iqela le-amino ukuze lisebenze ngakumbi.
Okwesibini, kwi-biochemistry, i-Cbz-N-Me-D-Ala-OH isebenza njengebhloko yokwakha i-molecule ye-bioactive.Ubume bayo be-amino acid yohlobo lwe-D lunika imisebenzi ekhethekileyo yebhayoloji, iyenza idlale indima ethile ekudityanisweni kweeproteni okanye amatyathanga epeptide.Ukongeza, inokuqeshwa njengeprobe okanye ileyibhile kwizifundo zebhayoloji ukuphanda intsebenziswano phakathi kweemolekyuli zebhayoloji.
Okokugqibela, ekufumaneni iziyobisi, i-Cbz-N-Me-D-Ala-OH ibambe ixabiso lonyango elinokubakho.Ubume bayo obukhethekileyo bekhemikhali kunye nomsebenzi webhayoloji unokuwenza abe ngumgqatswa weziyobisi othembisayo okanye ikhompawundi ekhokelayo.Ngokuguqulwa kwesakhiwo kunye nokulungiswa, kunokutyhila amandla onyango kunyango lwezifo okanye iimeko ezithile.
