Mapuroteni Zvinoumba: Chatinonyatsoziva nezvake?

Zvinozivikanwa kuti mapuroteni zvinokosha uye chikuru chikamu dzavamwe vapenyu muviri. Ndizvo avo vane basa muviri uye simba kutendeuka, iyo zvakabatana chaizvo kune vose anenge pezvakaitwa inokosha. Dry nyaya ruzhinji nyama uye nhengo zvemhuka uye vanhu, uye vanopfuura 50% zvigare zvose, kazhinji rinoumbwa mapuroteni (40% kusvika 50%). Vari chirimwa umambo hwavo chaiyo uremu zvichienzaniswa avhareji mutengo kushoma, uye mhuka - zvakawanda. Zvisinei, makemikari anoumba mapuroteni vanhu vazhinji kuchiri kuzivikanwa. Ngatiregei kamwe zvakare kuyeuka chii mukati izvi yakakwirira dzinongoitika Polymers.

mapuroteni Kuronga

Izvi fuma Paavhareji ane anenge 50-55% kabhoni, 15-17% senitrogen, 21-23% okisijeni, 0.3-2.5% nesarufa. Kuwedzera kune izvi zvinokosha zvinoriumba, dzimwe nguva ari mapuroteni zvinosanganisira zvinhu zvinoenderana yakaderera chaizvo. Kupfuura zvose, ichi phosphorus, simbi, ayodhini, mhangura nevamwe micro- uye macronutrients. Chinoshamisa, kuti senitrogen wevasungwa une chikuru kakawanda, asi zviri zvimwe kuurongwa dzingasiyana. Mukutsanangura mapuroteni mamiriro, hazvo zvinofanira kucherechedzwa kuti chinhu mugari polymer yakavakwa amino asidhi residues iri nzira iyo mvura mhinduro pa kwazvakarerekera ph rinonyanya rwevanhu chimiro kunyorwa sezvo NH3 + CHRCOO-.

Between izvi "Dzinovaka" vari akabatana nechimwe amide ukama pakati carboxyl uye amine mapoka. Zvose zvakasikwa kwakaratidza pamusoro zviuru mapurotini siyana. kirasi iyi antibodies, makemikari, hormone zhinji uye zvimwe vanoshingaira utachiona zvinhu. Zvinoshamisa, pasinei nezvose izvi kusiyana mapuroteni sezvamunoita zvingasanganisira asingapfuuri 30 vakasiyana amino acids, 20 iyo inonyanya kufarirwa. Muvanhu, vakawana 22 chete, vamwe hadzisi kunyura uye yabudiswa panze. Sere amino acids veboka iri kuonekwa chinokosha. It leucine, methionine, isoleucine, lysine, phenylalanine, tryptophan, threonine uye valine. Ndivo muviri wedu havagoni synthesize yavo, asi nokuda kwavo zvaida kudya kubva kunze. The yasara (taurine, arginine, glycine, carnitine, asparagine, histidine, cysteine, glutamine, alanine, ornithine, tyrosine, proline, naSerine, cystine), zvinogona kuti kusika vakazvimiririra. Saka, acids izvi amino vanoonekwa kuti kuchinjaniswa boka. Zvichienderana kana boka rokutanga puroteni, uyewo yaro mwero Absorção de Água nomuviri, puroteni rakakamurwa mukuru-mugiredhi uye vakaderera. Paavhareji daily kudya mwero zvinhu vanhu iri zvinobva 1 2 magiramu muzana kilogram kurema muviri. Panguva iyoyowo ndakagara vanhu vanofanira kunamatira yepazasi kuguma chikuva ichi, uye sporstmenov - pamusoro.

Sei kudzidza maumbirwo mapuroteni

Nokuti kudzidza izvi zvinhu zviri kunyanya kushandiswa hydrolysis nzira. The vandine mapuroteni kufarira iri neshungu pamwe sanganisa hydrochloric asidhi (6.10 mol / fő) pane imwe tembiricha inobva 100 kusvika 1100? C? C. Somugumisiro, izvozvo dziparare kuva musanganiswa amino acids kuti vava kupa munhu amino acids. Pari nokuti ari quantitative kuongorora zviri bvunzo mapuroteni akashandisa mapepa, uye Ion Exchange chromatography. Pane kunyange chaiyo otomatiki analyzers izvo nyore kurondedzera chaizvo izvo amino acids anobudiswa neZvapupu kuora.
