Ko te peptide he momo matū koiora i waenganui i ngā waikawa amino me ngā pūmua, he iti ake i te ngota pūmua, he iti ake te nui i te taumaha ngota o ngā waikawa amino, he kongakonga pūmua. E rua, neke atu rānei ngā waikawa amino e honoa ana e ngā hononga peptide hei hanga i tētahi "mekameka waikawa amino" he "rōpū waikawa amino" rānei, he peptide. I roto i ēnei, ko te peptide e titoa ana i te neke atu i te 10 ngā waikawa amino ka kiia he polypeptide, ā, ko te titoa ana i te 5 ki te 9 ngā waikawa amino ka kiia he oligopeptide, ko te titoa ana i te 2 ki te 3 ngā waikawa amino ka kiia he peptide ngota iti, mō te peptide poto iti.
He nui ake ngā painga o ngā peptide iti ake mai i te proteolysis tipu
I te whanaketanga o te rangahau, te whakaputa me te whakamahinga o ngā chelate huānga iti, kua āta mōhio te tangata ki te hiranga o te kai totika o ngā chelate huānga iti o ngā peptides iti. Ko ngā pūtake o ngā peptides ko ngā pūmua kararehe me ngā pūmua tipu. E whakamahi ana tā mātou kamupene i ngā peptides iti mai i te hydrolysis protease tipu, ā, he maha atu ngā painga: He haumaru koiora teitei, he tere te mimiti, he iti te kaha e pau ana i te mimiti, he uaua ki te whakakī i te kaikawe. E mōhiotia ana i tēnei wā he haumaru teitei, he nui te mimiti, he pumau teitei o te ligand chelate huānga iti.
Te whakataurite i te tauwehenga pumau i waenga i te parahi chelated waikawa amino me te parahi chelated peptide iti
Kua whakaatuhia e ngā rangahau he teitei ake te tauwehenga pumau o ngā peptide iti e herea ana ki ngā huānga iti i tērā o te herea o ngā waikawa amino ki ngā huānga iti.
Ngā kohuke iti kua whakakōpiritia ki te peptide (SPM)
Ko te chelate huānga iti o te peptide he mea hei wawahi i te protease tipu kounga teitei ki ngā peptide iti me te taumaha ngota o te 180-1000 Dalton (D) mā te whakamahi i te hydrolysis enzymatic aronga, te kutikuti me ētahi atu hangarau hydrolysis enzymatic koiora hohonu, kātahi ka whakarite i ngā katote konganuku kore-waro me ngā rōpū whakaritenga chelated (ngota hauota, ngota hāora) i roto i ngā ngota peptide iti mā te hangarau whakaritenga arotahi. Ko te peptide iti me te katote pokapū konganuku, ka hanga he chelate mowhiti kati. Ko ngā hua motuhake ko:Peptide parahi chelate, peptide ferrous chelate, peptide konutea chelate, peptide konupora chelate.
