Peptide ni ubwoko bw'ibintu bigize biokemike hagati ya aside amine na poroteyine, ni ntoya ugereranije na molekile ya poroteyine, ingano ni ntoya ugereranyije n'uburemere bwa aside amine, ni igice cya poroteyine. Aside amine ebyiri cyangwa nyinshi zihuzwa na peptide bonds kugira ngo zikore "uruhererekane rwa aside amine" cyangwa "icyiciro cya aside amine" ni peptide. Muri zo, peptide igizwe na aside amine zirenga 10 yitwa polipeptide, naho igizwe na aside amine 5 kugeza kuri 9 yitwa oligopeptide, igizwe na aside amine 2 kugeza kuri 3 yitwa peptide nto ya molecule, mu magambo make peptide nto.
Peptide ntoya zikomoka kuri proteolysis y'ibimera zifite ibyiza byinshi
Bitewe n’iterambere ry’ubushakashatsi, ikorwa n’ikoreshwa rya chelate z’ibice bito, abantu bagiye basobanukirwa akamaro k’imirire ya chelate z’ibice bito bya peptide nto. Inkomoko ya peptide irimo poroteyine z’inyamaswa na poroteyine z’ibimera. Isosiyete yacu ikoresha peptide nto zikomoka kuri hydrolysis ya protease y’ibimera ifite ibyiza byinshi: Kuba ifite umutekano mwinshi, kuyikurura vuba, gukoresha ingufu nke mu kuyikurura, kuyikurura ntibyoroshye. Ubu izwiho umutekano mwinshi, kuyikurura cyane, no kudahungabana kw’ibice bito bya chelate.
Kugereranya imiterere y'ubudahangarwa hagati y'umuringa ugizwe na aside amine na peptide ntoya hamwe n'umuringa ugizwe na peptide
Ubushakashatsi bwagaragaje ko ubushobozi bwo kugumana peptide ntoya zifatanye n’ibintu bito buruta ubw’aside amine zifatanye n’ibintu bito.
Imyunyu ngugu mito ya peptide chelated (SPM)
Chelate nto ya peptide trace element igamije gutandukanya poroteyine y’ibimera nziza cyane mo peptide nto zifite uburemere bwa molekile 180-1000 Dalton (D) hakoreshejwe ikoranabuhanga rya hydrolysis ya enzymatic directional, shearing n’ubundi buryo bwimbitse bwa enzyme hydrolysis, hanyuma igahuza iyoni z’icyuma zidafite organic hamwe n’amatsinda ya chelated coordination (atome za azote, atome za ogisijeni) muri molecule nto za peptide hifashishijwe ikoranabuhanga rya coordination. Peptide nto ifite iyoni yo hagati y’icyuma, ikora chelate y’impeta ifunze. Ibikoresho byihariye ni ibi:Peptide copper chelate, chelate ya ferrous peptide, peptide zinc chelate, peptide manganese chelate.
