UBWUMVIKANE BUTATATU KU BIREBANA NA KOLAGEN
Ubwa mbere, akenshi bivugwa ko "kolajenisi isoko nziza ya poroteyine yo kugaburira siporo."
Ku bijyanye n'imirire y'ibanze, kolajeni rimwe na rimwe ishyirwa mu cyiciro cy'isoko rya poroteyine ituzuye hakurikijwe uburyo busanzwe bwo gusuzuma ubuziranenge bwa poroteyine bitewe n'uko aside amine nkeya ifite. Ariko, uruhare rwa kolajeni mu mirire rurenze uruhare rw'ibanze rwa poroteyine mu bijyanye no gutanga aside amine z'ingenzi kugira ngo ihaze ibyo ikeneye buri munsi. Bitewe n'imiterere yayo yihariye ya peptide, peptide za kolajeni zikora (BCP) zifatanya n'udukingirizo tw'uturemangingo runaka kandi zigatera imbaraga ikorwa rya poroteyine zo hanze y'uturemangingo. Ingaruka zayo ntaho zihuriye n'imiterere y'aside amine z'ingenzi cyangwa amanota y'ubuziranenge bwa poroteyine ya kolajeni.
Icya kabiri, abaguzi bari mu rujijo ku bijyanye n'uburyo peptide za kolajeni zishyirwa mu byiciro.
Uburyo kolajeni ikwirakwira mu mubiri ni ingenzi cyane. Ariko aho yaba iri hose, gushyira ubwoko bwa kolajeni mu byiciro (28 byamaze kumenyekana kugeza ubu) ntibigira ingaruka ku mikorere ya peptide za kolajeni zabo nk'isoko y'imirire. Urugero, nk'uko byagaragajwe n'igerageza ritandukanye ryakozwe mbere yo kuvura, kolajeni yo mu bwoko bwa I n'iya II bigaragaza poroteyine imwe (hafi 85%), kandi iyo kolajeni yo mu bwoko bwa I n'iya II zihiye muri peptide, itandukaniro ryazo nta ngaruka rigira ku mikorere ya peptide za kolajeni cyangwa ku buryo uturemangingo twazo turushaho gukanguka.
Icya gatatu, peptide za kolajeni mu mubiri ntizishobora kugongwa na enzymes mu mara.
Ugereranyije n'izindi poroteyine, kolajeni ifite imiterere yihariye y'uruhererekane rw'aside amine ifasha mu gutwara peptides zikora neza mu mara. Ugereranyije n'imiterere ya α helical y'izindi poroteyine, peptides za kolajeni zikora neza zifite imiterere miremire kandi irinda hydrolysis y'amara. Iyi miterere ituma igira akamaro mu kwinjiza no gutuza mu mara.
Muri iki gihe, kurya biri kurenza ibyo ukeneye by'ibanze ahubwo byibanda ku aside amine z'ingenzi n'ibikomoka ku biribwa bitanga umusaruro nk'ibigenga imikorere y'umubiri bishobora kuzana inyungu nziza kandi z'igihe kirekire ku buzima bw'umubiri no guhaza ibyo ukeneye mu mikorere y'umubiri nko kurwanya gusaza no kugabanya imvune za siporo. Ku bijyanye n'ubumenyi bw'abaguzi, kolajeni yabaye imwe mu masoko y'ingenzi ya peptides zikora.
