Peptide yog ib hom tshuaj biochemical ntawm cov amino acids thiab cov protein, nws me dua li cov protein molecule, qhov ntau me dua li qhov hnyav molecular ntawm amino acids, yog ib feem ntawm cov protein. Ob lossis ntau dua amino acids txuas nrog peptide bonds los tsim ib "saw ntawm amino acids" lossis "pawg ntawm amino acids" yog peptide. Ntawm lawv, ib qho peptide uas muaj ntau dua 10 amino acids hu ua polypeptide, thiab muaj 5 txog 9 amino acids hu ua oligopeptide, muaj 2 txog 3 amino acids hu ua molecule me peptide, rau luv luv peptide me.
Cov peptides me me los ntawm cov nroj tsuag proteolysis muaj ntau qhov zoo dua
Nrog rau kev txhim kho ntawm kev tshawb fawb, kev tsim khoom thiab kev siv cov kab kawm chelates, tib neeg tau maj mam paub txog qhov tseem ceeb ntawm kev noj zaub mov ntawm cov kab kawm chelates ntawm cov peptides me me. Cov peev txheej ntawm peptides suav nrog cov protein tsiaj thiab cov protein cog. Peb lub tuam txhab siv cov peptides me me los ntawm cov nroj tsuag protease hydrolysis muaj ntau qhov zoo: Kev nyab xeeb ntawm lub cev siab, kev nqus sai, kev siv hluav taws xob tsawg ntawm kev nqus, tus neeg nqa khoom tsis yooj yim rau saturate. Tam sim no nws paub tias muaj kev nyab xeeb siab, kev nqus siab, kev ruaj khov siab ntawm cov kab kawm chelate ligand.
Kev sib piv ntawm cov coefficient ruaj khov ntawm amino acid chelated tooj liab thiab peptide me me chelated tooj liab
Cov kev tshawb fawb tau qhia tias qhov kev ruaj khov ntawm cov peptides me me uas khi rau cov kab kawm yog siab dua li ntawm cov amino acids uas khi rau cov kab kawm.
Cov zaub mov me me peptide chelated (SPM)
Cov peptide me me trace element chelate yog los rhuav tshem cov protease zoo ntawm cov nroj tsuag mus rau hauv cov peptides me me nrog qhov hnyav molecular ntawm 180-1000 Dalton (D) los ntawm kev siv cov txheej txheem enzymatic hydrolysis, shearing thiab lwm yam kev siv tshuab enzymatic hydrolysis tob tob, thiab tom qab ntawd sib koom tes cov hlau inorganic nrog cov pab pawg sib koom tes chelated (nitrogen atoms, oxygen atoms) hauv cov peptide me me los ntawm kev tsom mus rau kev sib koom tes thev naus laus zis. Cov peptide me me nrog cov hlau hauv nruab nrab ion, tsim lub nplhaib kaw chelate. Cov khoom tshwj xeeb yog:Peptide tooj liab chelate, peptide ferrous chelate, peptide zinc chelate, peptide manganese chelate.
