Selelekela

Cbz-pyroglutamic acid (carbobenzoxy-L-phenylalanine) ke motsoako oa tlhaho o sebelisoang hangata e le sehlopha se sireletsang amino acid k'hemistri. Lintho tsa eona tsa lik'hemik'hale li tiile ka kristale e tšoeu, li qhibiliha ka har'a metsoako ea tlhaho e kang ethanol le chloroform, e ke keng ea qhibiliha metsing.

 

E 'ngoe ea litšebeliso tse ka sehloohong tsa CBZ-pyroglutamic acid ke ho sebetsa e le sehlopha se sireletsang sa li-amino acid ka har'a motsoako o tiileng. E ka etsa sebopeho se tsitsitseng sa amide ka ho sebetsana le sehlopha sa α-amino sa amino acid ho thibela liketso tse ling hore li se ke tsa etsahala. Ha ho etsoa li-peptide kapa liprotheine, Cbz-pyroglutamic acid e ka sebelisoa ho sireletsa masala a itseng a amino acid.

 

Mokhoa oa ho lokisa Cbz-pyroglutamic acid ka kakaretso ke ho itšoara ka pyroglutamic acid le dibenzoyl carbonate (e lokiselitsoeng ke karabelo ea dibenzoyl chloride le sodium carbonate) tlas'a maemo a alkaline. Mokhoa oa ho itokisa o hloka ho sebetsoa ka hloko ho qoba litlamorao kapa lintho tse kotsi.

 

Lintlha tsa polokeho: Cbz-pyroglutamic acid ke ntho e tukang, qoba ho kopana ka kotloloho le mehloli ea mollo. Lisebelisoa tse loketseng tsa ho itšireletsa, tse kang liatlana tsa laboratori le likhalase, li lokela ho apesoa ha li tšoaroa. Qoba ho hema lerōle kapa tharollo ea eona kaha e ka baka ho halefisa tsamaiso ea ho hema. Nakong ea ho boloka le ho tšoara, tlhokomelo e lokela ho nkoa ho tiisa setshelo le ho se boloka hole le mehloli ea mollo le lisebelisoa tse tukang.
