Vuga muri make glycine na alanine

Muri iyi nyandiko, hamenyekanye aside aside ebyiri z'ibanze, glycine (Gly) na alanine (Ala).Ibi biterwa cyane cyane nuko zishobora gukora nka acide ya amino acide no kubongerera amatsinda bishobora kubyara ubundi bwoko bwa aside amine.

Glycine ifite uburyohe budasanzwe, izina ryicyongereza rero riva mubigereki glykys (biryoshye).Ubushinwa bwahinduwe na glycine ntabwo bufite ubusobanuro bw '"uburyohe" gusa, ahubwo bufite nuburyo busa, bushobora kwitwa icyitegererezo cy "ubudahemuka, ibyagezweho na elegance".Kubera uburyohe bwayo, glycine ikunze gukoreshwa nkibintu bihumura mu nganda zibiribwa kugirango bikureho umururazi no kongera uburyohe.Urunigi rw'uruhande rwa glycine ni nto hamwe na atome imwe ya hydrogen.Ibyo bituma atandukana.Nibintu byibanze bya aside amine idafite chirality.

Glycine muri poroteyine irangwa nubunini bwayo kandi bworoshye.Kurugero, imirongo itatu ya helix ihinduka ya kolagen irihariye.Hagomba kubaho glycine imwe kuri buri bisigazwa bibiri, bitabaye ibyo bizatera inzitizi zikomeye cyane.Mu buryo nk'ubwo, guhuza ibice bibiri bya poroteyine akenshi bisaba glycine kugirango ihuze neza.Ariko, niba glycine ihinduka bihagije, ituze ryayo byanze bikunze bidahagije.

Glycine nimwe mubangiza mugihe α-helix.Impamvu nuko iminyururu yo kuruhande ari nto cyane kugirango ihindure ihinduka rwose.Byongeye kandi, glycine ikoreshwa mugutegura ibisubizo bya buffer.Mwebwe abakora electrophoreis bakunze kubyibuka.

Izina ry'icyongereza rya alanine rikomoka mu kidage acetaldehyde, kandi izina ry'igishinwa biroroshye kubyumva kuko alanine irimo karubone eshatu n'izina ryayo ry'imiti ni alanine.Iri ni izina ryoroshye, kimwe nimiterere ya aside amine.Urunigi rwuruhande rwa alanine rufite methyl groupe imwe gusa kandi nini cyane kurenza glycine.Iyo nashushanyije formulaire yuburyo bwa 18 aminide acide, nongeyeho amatsinda kuri alanine.Muri poroteyine, alanine ni nk'amatafari, ibikoresho rusange byubaka bitavuguruzanya numuntu.

Urunigi rw'uruhande rwa alanine rufite imbogamizi nke kandi ruherereye muri α-helix, ni ihinduka.Birahagaze neza cyane iyo β-bikubye.Mu buhanga bwa poroteyine, niba ushaka guhindura aside amine idafite intego yihariye kuri poroteyine, muri rusange ushobora kuyihindura kuri alanine, ntibyoroshye gusenya ihinduka rusange rya poroteyine.
