Protein kunye obisi haydrolisis

Protein - yinto yemichiza yikhompawundi kweziphilayo uhlobo ophezulu. Njengenxenye kwiproteni, kukho angaphezu kwekhulu acid iintsalela ezahlukeneyo. Umntu ngamnye emzimbeni wakhe ukuba angabi wayedla ngaphantsi kwe elinesihlanu iiprothini.

Iiproteni unokuba iintlobo ezininzi:

1. ngeeProteni uhlobo peptide elula. Baya kuba namalungu angekho ngaphezulu kwe kwekhulu acid acid iintsalela.

2. Proteins oligopeptide uhlobo. Ziquka ezimbini ukuya ezilishumi acid acid iintsalela kwi kwikhonkco.

3. uhlobo polypeptide ngeeProteni. Ziquka ukusuka kwishumi ukuya nekhulu acid acid iintsalela kwi kwikhonkco.

Kufuneka kwakhona ukuba bathi iiproteni ukuze ube ngomnye iintlobo ezine lombutho:

1. Le fom iphambili kwiproteni. Kule fomu ye kwiproteni amelwe zinemoletyhule yomgama elakhiwe ngolandelelwano zeentsalela acid acid.

2. Olu luhlobo yesibini protini. Kule fomu ye kwiproteni batshintshwa kwisithuba, it yakha uhlobo ephotheneyo, esixhaswa yi imixokelelwane hydrogen.

3. Olu hlobo protein ephakamileyo. Kule fomu, esebenzisa iintlobo ngeentlobo odibanisa uwele protein ukugoba molecule nezibaya zibe uhlobo simile, ekuthiwa ukubizwa chemistry globule.

4. luhlobo koqeqesho le protini. Kulo mzekelo, iimolekyuli ziiprotein eziliqela ukwenza globules ayinakutshintshwa ukuya kwenye nenye link.

Xa neprothini kwenzeka nayiphi na impembelelo lwangaphandle, umzekelo, impembelelo yeemeko ezifana lobushushu eziphakamileyo, kwemolekyuli iproteni iqala maxongo ngokuthe zenze imilo. Kodwa xa, ekugqibeleni, ukutshabalala primary isakhiwo kwiproteni, ngoko esiya kuthi, ukuba haydrolisis kweziyi yenzekile. Haydrolisis kweziyi - inkqubo yinqobo ngokutshatyalaliswa uhlobo engundoqo kwemolekyuli protini. Le yinkqubo entsonkothileyo Inokwenzeka zombini esidi aphakathi kuhlobo medium obrak. Ngukhuleka yinxalenye yenkqubo zendalo, ezifana haydrolisis kweziyi emzimbeni, yinto enzyme - peptidase - hydrolase. Haydrolisis kweziyi - oku linqanam lokugqibela ukutshatyalaliswa protein-yohlobo iimolekyuli. Ukutshatyalaliswa iifom lesibini okanye ngaphezulu okuthiwa nokuguqulwa. Nokuguqulwa kungenzeka lwalo ingathityazwa lakho. nokuguqulwa umva kwenzeka ekwaphukeni lamakhonkco elibuthathaka kwemolekyuli protein, nelungu lakho - waphula umthetho oluntsonkothileyo obusenyongweni covalent.

Oku kubalulekile kakhulu kwiimveliso ebomini bethu njengobisi, kakhulu, ukuba ubukhulu becala ziyilwe protini. protein yayo iquka la macandelo:

1. I-protein casein. Ifumaneka ngobisi malunga amathathu ekhulwini.

2. Laktobulmin. Uye kumafa wayo likufutshane protein, nto leyo ifumaneka serum igazi. Efunyanwa kulo nobisi malunga nesiqingatha ekhulwini.

3. Lactoglobulin. Le iproteni kuhle kakhulu ukuba amajoni omzimba. Kuye imikhosi zintsholongwane kunye nezifo.

I protein ngobisi kunokuba kuphela ukwimeko enyibilikayo, kwaye ifunxwe ukusetyenziswa kwayo ukutya ukuya kumashumi asithoba anesibhozo ekhulwini. Idlala indima ebaluleke kakhulu emzimbeni, kusetyenziswa njengoko ukutya. injongo yawo - ukuba bathathe inxaxheba ukuyilwa iiseli ezintsha emzimbeni, ingakumbi eziphilayo abaselula, izityalo kunye nezilwanyana, kwakunye njengoko kunceda ukubuyisela iiseli ezindala.

Ubisi, kubandakanywa, inokuba liqulathe inani le iiproteni serum imvelaphi okanye ezinye imvelaphi efanayo. iiproteni ngenisa ubisi iiseli mammary ndlala yaye, enyanisweni, ezi mveliso kwemisebenzi komzimba kubalulekile, nto leyo ithathwa kwimveliso. Kwakhona, obisi iqulethe ezininzi asidi kubalulekile acid ayikwazi kuhlanganiswa emzimbeni, kodwa kunjalo kuyimfuneko ukuba ikho phambili kunye nokusebenza.
