Peptide ni iki?

Peptede yerekeza kubwoko bw'ikigo gifite molecular imiterere iri hagati ya amino na poroteyine, igizwe nubwoko 20 bwa aside amine mu bihe bitandukanye, uhereye kuri buri murongo cyangwa uruziga ruzenguruka. Buri peptade ifite imiterere yihariye, kandi imiterere ya buri gihe ishingiye kumikorere yabo. Peptide ifite ibikurikirano mu mubiri wibinyabuzima, ariko ifite ibikorwa bidasanzwe bya physiologiya. Muri bo, buriye ashobora kugena ibinyabuzima bya physiologiya byitwa imikorere ya pepteal cyangwa bishingiye kuri biologiya. Mu ntangiriro ya 20^thIkinyejana, intsinzi yo guhuza imiti ya dipeptide isinya isura ya siyanse ya Peptide.

Ibintu byinshi byerekana ko poroteyine idashobora kwikuramo gusa muburyo bwa Acino, ariko kandi ikurura muburyo bwinshi bwo kuringaniza. Muri rusange bizera ko dipeptide kandi ikaba yinjije mumirongo yinyama hanyuma isuku ya peptidase kugirango yinjire kuzenguruka amaraso muburyo bwa acide yubusa acide. Umutwara peptide yinjira kuzenguruka.

Ubushakashatsi bwasanze poroteyine yinjijwe mu mubiri w'umuntu irimo gukubitwa kandi yinjiye mu buryo bwa Oligsopée nyuma y'ibikorwa by'igifuniko, kandi igipimo cyo kwinjiza mu nzira y'igifuniko, kandi igipimo cyo kwinjiza mu buryo bw'ubusa acide ni gito cyane.

Poroteyine yinjijwe muburyo bwa peptide, ntabwo yirinda gusa amarushanwa hagati ya Amine gusa, ariko kandi bigabanya ingaruka mbi zumuvuduko mwinshi wumubiri wumuntu. Kubwibyo, tanga umubiri wumubiri muburyo bwa peptide nibyiza kugirango ugire imbaraga zidakorwa za peptide. Ikirenzeho, valensi ya kamere hamwe nimirire agaciro ya peptide iri hejuru kuruta acide ya amine. Kubwibyo, peptide ya coptade yahindutse ahantu hashyushye mu murima wa proteine ​​itoneratoine, na peptide ntoya cyangwa oligeppeptide ifata ibiryo byiza mu kanwa ifite ishingiro rya siyansi.
