Ubale Pakati pa Mapuloteni, Ma Peptidi, ndi Ma Amino Acids
Mapuloteni: Ma macromolecule ogwira ntchito opangidwa ndi unyolo umodzi kapena angapo a polypeptide omwe amapinda m'mapangidwe enieni amitundu itatu kudzera mu ma helices, mapepala, ndi zina zotero.
Ma unyolo a Polypeptide: Mamolekyu ofanana ndi unyolo opangidwa ndi ma amino acid awiri kapena kuposerapo olumikizidwa ndi ma peptide bonds.
Ma Amino Acids: Mapuloteni oyambira; mitundu yoposa 20 ilipo m'chilengedwe.
Mwachidule, mapuloteni amapangidwa ndi unyolo wa polypeptide, womwe umapangidwa ndi ma amino acid.
Njira Yogaya ndi Kuyamwa Mapuloteni mwa Zinyama
Kumwa Pamaso: Chakudya chimaphwanyidwa mwa kutafuna mkamwa, zomwe zimapangitsa kuti pakhale enzyme yogaya chakudya. Popeza mkamwa mulibe ma enzyme ogaya chakudya, sitepe iyi imaonedwa ngati kugaya chakudya mwamakina.
Kuwonongeka Koyamba M'mimba:
Mapuloteni ogawanika akalowa m'mimba, asidi wa m'mimba amawachotsa, zomwe zimapangitsa kuti ma peptide bond awonekere. Kenako Pepsin amaswa mapuloteniwo m'njira ya enzymatic kukhala ma polypeptide akuluakulu, omwe pambuyo pake amalowa m'matumbo ang'onoang'ono.
Kugaya chakudya m'matumbo ang'onoang'ono: Trypsin ndi chymotrypsin m'matumbo ang'onoang'ono zimaphwanyanso ma polypeptide kukhala ma peptide ang'onoang'ono (dipeptides kapena tripeptides) ndi ma amino acid. Kenako izi zimalowa m'maselo a m'matumbo kudzera mu njira zoyendera ma amino acid kapena njira yoyendera ma peptide ang'onoang'ono.
Mu zakudya za nyama, zinthu zotsalira za protein-chelated ndi zinthu zazing'ono zotsalira za peptide-chelated zimapangitsa kuti zinthu zotsalira zikhalepo kudzera mu chelation, koma zimasiyana kwambiri mu njira zawo zoyamwitsa, kukhazikika, ndi zochitika zoyenera. Zotsatirazi zikupereka kusanthula koyerekeza kuchokera ku mbali zinayi: njira yoyamwitsa, mawonekedwe a kapangidwe kake, zotsatira za kagwiritsidwe ntchito, ndi zochitika zoyenera.
1. Njira Yoyamwira:
| Chizindikiro Choyerekeza | Zinthu Zotsatizana ndi Mapuloteni | Zinthu Zochepa Zokhala ndi Peptide |
|---|---|---|
| Tanthauzo | Ma Chelates amagwiritsa ntchito mapuloteni akuluakulu (monga hydrolyzed plant protein, whey protein) ngati zonyamulira. Ma ayoni achitsulo (monga Fe²⁺, Zn²⁺) amapanga mgwirizano wogwirizana ndi magulu a carboxyl (-COOH) ndi amino (-NH₂) a amino acid residues. | Amagwiritsa ntchito ma peptide ang'onoang'ono (opangidwa ndi ma amino acid 2-3) ngati zonyamulira. Ma ayoni achitsulo amapanga ma chelate a mphete okhala ndi ziwalo zisanu kapena zisanu ndi chimodzi okhazikika okhala ndi magulu a amino, magulu a carboxyl, ndi magulu a unyolo wam'mbali. |
| Njira Yoyamwira | Amafuna kugawikana ndi ma protease (monga trypsin) m'matumbo kukhala ma peptide ang'onoang'ono kapena ma amino acid, kutulutsa ma ayoni achitsulo opangidwa ndi chelated. Kenako ma ayoni awa amalowa m'magazi kudzera mu kufalikira kwa magazi kapena mayendedwe ogwira ntchito kudzera munjira za ma ion (monga DMT1, ZIP/ZnT transporters) pa maselo a epithelial am'mimba. | Imatha kuyamwa ngati ma chelate osawonongeka mwachindunji kudzera mu peptide transporter (PepT1) pa maselo a epithelial am'mimba. Mkati mwa selo, ma ayoni achitsulo amatulutsidwa ndi ma enzymes amkati mwa selo. |
| Zoletsa | Ngati ntchito ya ma enzymes ogaya chakudya si yokwanira (monga mwa nyama zazing'ono kapena zomwe zili ndi nkhawa), mphamvu ya kusweka kwa mapuloteni imakhala yochepa. Izi zitha kubweretsa kusokonekera msanga kwa kapangidwe ka chelate, zomwe zimapangitsa kuti ma ayoni achitsulo azilumikizidwa ndi zinthu zotsutsana ndi zakudya monga phytate, zomwe zimachepetsa kugwiritsidwa ntchito. | Imadutsa m'mimba mopingasa (monga phytic acid), ndipo kuyamwa sikudalira ntchito ya ma enzymes ogaya chakudya. Ndi yoyenera makamaka nyama zazing'ono zomwe zili ndi kugaya chakudya kosakhwima kapena nyama zodwala/zofooka. |
2. Makhalidwe ndi Kukhazikika kwa Kapangidwe ka Kapangidwe:
| Khalidwe | Zinthu Zotsatizana ndi Mapuloteni | Zinthu Zochepa Zokhala ndi Peptide |
|---|---|---|
| Kulemera kwa Maselo | Lalikulu (5,000~20,000 Da) | Kakang'ono (200~500 Da) |
| Mphamvu ya Chelate Bond | Ma bond angapo ogwirizana, koma mawonekedwe ovuta a mamolekyulu amachititsa kuti pakhale bata lapakati. | Kapangidwe ka peptide kakafupi kosavuta kamalola kupangidwa kwa mapangidwe a mphete okhazikika. |
| Luso Loletsa Kusokoneza | Amakhudzidwa ndi asidi m'mimba komanso kusinthasintha kwa pH m'matumbo. | Kukana asidi ndi alkali kwambiri; kukhazikika kwakukulu m'matumbo. |
3. Zotsatira za Kugwiritsa Ntchito:
| Chizindikiro | Mapuloteni a Chelate | Ma Chelate Ang'onoang'ono a Peptide |
|---|---|---|
| Kupezeka kwa zinthu zachilengedwe | Zimadalira ntchito ya ma enzymes ogaya chakudya. Zimathandiza kwambiri nyama zazikulu zathanzi, koma mphamvu yake imachepa kwambiri mwa nyama zazing'ono kapena zopsinjika. | Chifukwa cha njira yoyamwira mwachindunji komanso kapangidwe kokhazikika, kupezeka kwa zinthu zochepa ndi 10% ~ 30% kuposa kwa mapuloteni a chelate. |
| Kukulitsa Ntchito | Kagwiridwe kake kofooka, makamaka ngati zonyamulira zinthu zochepa. | Ma peptide ang'onoang'ono okha ali ndi ntchito monga kulamulira chitetezo cha mthupi ndi ntchito yoteteza ku ma antioxidants, zomwe zimapangitsa kuti pakhale mgwirizano wamphamvu ndi zinthu zochepa (monga Selenomethionine peptide imapereka ntchito zowonjezera selenium komanso zoteteza ku ma antioxidants). |
4. Zochitika Zoyenera ndi Zoganizira Zachuma:
| Chizindikiro | Zinthu Zotsatizana ndi Mapuloteni | Zinthu Zochepa Zokhala ndi Peptide |
|---|---|---|
| Zinyama Zoyenera | Ziweto zazikulu zathanzi (monga nkhumba zomaliza, nkhuku zoyamwitsa) | Zinyama zazing'ono, nyama zomwe zili pansi pamavuto, mitundu ya m'madzi yobala zipatso zambiri |
| Mtengo | Zotsika (zipangizo zoyambira zomwe zimapezeka mosavuta, njira yosavuta) | Zapamwamba (mtengo wokwera wa kapangidwe ka peptide kakang'ono ndi kuyeretsa) |
| Zotsatira za Chilengedwe | Zigawo zosayamwa zitha kutuluka mu ndowe, zomwe zingawononge chilengedwe. | Kugwiritsa ntchito kwambiri, chiopsezo chotsika cha kuipitsidwa kwa chilengedwe. |
Chidule:
(1) Kwa nyama zomwe zimafunikira zinthu zambiri zosafunikira komanso zomwe zimalephera kugaya chakudya (monga ana a nkhumba, anapiye, mphutsi za nkhanu), kapena nyama zomwe zimafuna kukonza zofooka mwachangu, ma peptide chelates ang'onoang'ono amalimbikitsidwa ngati chisankho chofunikira kwambiri.
(2) Kwa magulu omwe amadya zakudya zotsika mtengo komanso omwe amagwira ntchito bwino m'mimba (monga ziweto ndi nkhuku zomwe zili kumapeto kwa nthawi yomaliza), zinthu zotsalira za mapuloteni zimatha kusankhidwa.
