Isingeniso
I-Cbz-pyroglutamic acid (carbobenzoxy-L-phenylalanine) iyinhlanganisela yemvelo evame ukusetshenziswa njengeqembu elivikela ama-amino acid kukhemistri. Izakhiwo zayo zamakhemikhali ziyi-white crystalline solid, encibilika kuzincibilikisi eziphilayo ezifana ne-ethanol ne-chloroform, engancibiliki emanzini.
Okunye ukusetshenziswa okuyinhloko kwe-CBZ-pyroglutamic acid ukwenza njengeqembu elivikelayo lama-amino acid ekuhlanganiseni kwesigaba esiqinile. Ingakha isakhiwo se-amide esizinzile ngokusabela neqembu le-α-amino lama-amino acid ukuvimbela okunye ukusabela ukuthi kungenzeki. Lapho kuhlanganiswa ama-peptide noma amaprotheni, i-Cbz-pyroglutamic acid ingasetshenziswa ukuvikela izinsalela ezithile ze-amino acid.
Indlela yokulungisa i-Cbz-pyroglutamic acid ngokuvamile iwukusabela i-pyroglutamic acid ne dibenzoyl carbonate (elungiselelwe ukusabela kwe dibenzoyl chloride ne-sodium carbonate) ngaphansi kwezimo ze-alkali. Inqubo yokulungiselela idinga ukuphathwa ngokucophelela ukuze kugwenywe ukusabela okuseceleni noma izinto eziyingozi.
Ulwazi lokuphepha: I-Cbz-pyroglutamic acid iyinto evuthayo, gwema ukuthintana ngqo nemithombo yokuthungela. Izimpahla zokuzivikela ezifanele, njengamagilavu aselabhorethri nezibuko, kufanele zigqokwe ngesikhathi sokuphatha. Gwema ukuhogela uthuli lwayo noma isixazululo njengoba kungase kubangele ukucasuka ohlelweni lokuphefumula. Ngesikhathi sokugcina nokuphatha, kufanele kuthathwe ukunakekelwa ukuze uvale isitsha futhi usigcine kude nemithombo yomlilo kanye nezinto ezivuthayo.
