Sootaga i le va o Polotini, Peptides, ma Amino Acids
Polotini: O macromolecules galue e faia e se tasi pe sili atu filifili polypeptide gaugau i ni fausaga faʻapitoa tolu-dimensional e ala i helices, laupepa, ma isi.
Polypeptide Chains: Molelaula pei o filifili e fausia i ni amino acids se lua pe sili atu e feso'ota'i i fusi peptide.
Amino Acids: O poloka fau faavae o polotini; sili atu i le 20 ituaiga o loʻo iai i le natura.
I se aotelega, o polotini o loʻo faia i filifili polypeptide, lea o loʻo i ai i le amino acids.
Fa'agasologa ole Fa'ali'iina ole Polotini ma Fa'asa'o ile Manu
Togafitiga Taugutu: E malepelepe fa'aletino mea'ai e ala ile lamu ile gutu, fa'atuputeleina le pito i luga ole mea'ai mo le fa'amamaina ole enzymatic. Ona o le gutu e leai ni enzymes digestive, o lenei laasaga ua taʻua o le faʻaogaina o masini.
Muamua malepe i le manava:
A mae'a ona ulu atu polotini vaevae i totonu o le manava, e fa'aleagaina e le gastric acid, ma fa'aalia ai fusi peptide. Pepsin ona talepeina lea e le enzymatically ia polotini i polypeptides mole mole tetele, lea e oo atu i totonu o le tootoo laiti.
Fa'aliga i totonu o le To'oto'o Laiti: Trypsin ma le chymotrypsin i totonu o le tootoo la'ititi e toe talepeina le polypeptides i ni peptides laiti (dipeptides po'o tripeptides) ma amino acids. O nei mea e faʻafefe i totonu o sela o le intestinal e ala i le amino acid transport systems poʻo le laʻititi o le peptide transport system.
I mea'ai a manu, o mea uma e lua o le protein-chelated trace elements ma mea laiti peptide-chelated trace elements e faʻaleleia ai le bioavailability o elemene elemene e ala i le chelation, ae e matua ese lava i latou faʻaogaina masini, mautu, ma faʻataʻitaʻiga talafeagai. O mea nei o lo'o tu'uina atu ai se fa'atusatusaga o su'esu'ega mai vaega e fa: fa'aogaina o masini, fa'atulagaga fa'atulagaina, fa'aogaina o a'afiaga, ma fa'aaliga talafeagai.
1. Fa'ainitaneti ole absorption:
| Fa'ailoga Fa'atusatusa | Polotini-chelated Trace Elements | Laiti Peptide-chelated Trace Elements |
|---|---|---|
| Uiga | E fa'aogaina e Chelates polotini macromolecular (fa'ata'ita'iga, polotini o la'au hydrolyzed, porotini whey) e ave ai. O iona u'amea (fa'ata'ita'iga, Fe²⁺, Zn²⁺) e fai fa'atasi fa'atasi ma le carboxyl (-COOH) ma le amino (-NH₂) vaega o toega amino acid. | Fa'aaogā tama'i peptide (e aofia ai le 2-3 amino acids) e avea ma fe'avea'i. O ion u'amea e sili atu ona mautu lima po'o ono-membered mama chelates ma vaega amino, vaega carboxyl, ma vaega filifili filifili. |
| Auala mo'i | Manaomia le talepeina e protease (fa'ata'ita'iga, trypsin) i totonu o le inumaga i ni peptides laiti po'o ni amino acids, fa'asa'oloto ai ion uamea. O nei ion e o'o atu i le toto e ala i le fa'asalalauina fa'agasolo po'o felauaiga fa'agaoioi e ala i alavai (eg, DMT1, ZIP/ZnT transporters) i luga o sela epithelial intestinal. | E mafai ona mitiia e pei o chelates le atoatoa e ala i le peptide transporter (PepT1) i luga o sela epithelial intestinal. I totonu o le sela, ua faamatuu atu ions uamea e enzymes intracellular. |
| Tapulaa | Afai e le lava le gaioiga o enzymes digestive (fa'ata'ita'iga, i manu laiti po'o i lalo o le atuatuvale), e maualalo le lelei o le malepelepe. O lenei mea e ono mafua ai le faʻalavelave vave o le fausaga o le chelate, faʻatagaina ions uʻamea e saisaitia e mea e faʻaleagaina ai meaʻai pei o le phytate, faʻaitiitia le faʻaaogaina. | 'Alo'ese le fa'atauva'a fa'atauva'a (fa'ata'ita'iga, mai le phytic acid), ma e le fa'alagolago le fa'aaogāina i le fa'aogaina o le enzyme. Aemaise lava le talafeagai mo manu laiti e le o matua le faiga o mea'ai po'o manu mamai/vaivai. |
2. Uiga Fa'avae ma Mausali:
| Uiga | Polotini-chelated Trace Elements | Laiti Peptide-chelated Trace Elements |
|---|---|---|
| Molecular Weight | Tele (5,000~20,000 Da) | Laiti (200~500 Da) |
| Malosi o Nonoa Chelate | Fa'amaopoopo fa'atasi, ae lavelave mole fa'aogaina e ta'ita'i atu i le mautu masani. | Fa'ata'ita'iga faigofie peptide fa'ataga e fa'atūina ai ni fa'amaumau mama. |
| Malosiaga e tetee atu i le faalavelave | Fa'aaafia ile a'afiaga ole gastric acid ma fesuiaiga ile pH ole intestinal. | Sili atu le malosi o le acid ma le alkali; mautu maualuga i le siosiomaga intestinal. |
3. Aafiaga o Fa'aoga:
| Fa'ailoga | Polotini Chelates | Laiti Peptide Chelates |
|---|---|---|
| Bioavailability | Fa'alagolago ile gaioiga ole digestive enzyme. E aoga i manu matutua soifua maloloina, ae fa'aitiitia le lelei i manu laiti po'o manu mamafa. | Ona o le auala absorption tuusaʻo ma fausaga mautu, suʻesuʻeina elemene bioavailability o 10% ~ 30% maualuga atu nai lo protein chelates. |
| Fa'alautelega Fa'atino | E fai si vaivai le fa'atinoga, fa'amuamua e avea ma fa'auluina elemene. | O tama'i peptide lava latou e iai galuega e pei o le puipuiga o le tino ma le antioxidant activity, e maua ai le malosi fa'atasi ma elemene (fa'ata'ita'iga, Selenomethionine peptide e maua uma le seleni supplementation ma antioxidant functions). |
4. Tala talafeagai ma Manatuga Tau Tamaoaiga:
| Fa'ailoga | Polotini-chelated Trace Elements | Laiti Peptide-chelated Trace Elements |
|---|---|---|
| Manu talafeagai | Manu matutua soifua maloloina (fa'ata'ita'iga, puaa fa'auma, moa fa'ataoto) | Manu laiti, manu i lalo o le faʻalavelave, maualuga-fua mai meaola vai |
| Tau | Maulalo (meamata e maua, faigofie faiga) | Maualuga (maualuga le tau o le faʻaogaina o le peptide laʻititi ma le faʻamamaina) |
| Aafiaga Faalesiosiomaga | O vaega e le'i fa'asa'o e mafai ona alu i fei, e ono fa'aleagaina ai le si'osi'omaga. | Ole maualuga ole fa'aoga, fa'aitiitia le lamatiaga ole fa'aleagaina ole si'osi'omaga. |
Aotelega:
(1) Mo manu e maualuga mea e mana'omia ma vaivai le gafatia o mea'ai (fa'ata'ita'iga, puaa, moa, ula ula), po'o manu e mana'omia le vave fa'asa'o o faaletonu, o tama'i peptide chelate e fautuaina e fai ma filifiliga fa'amuamua.
(2) Mo kulupu e ma'ale'ale tau o lo'o i ai le fa'agaioiga masani o mea'ai (fa'ata'ita'iga, lafumanu ma moa i le tuai o le fa'amae'aina), e mafai ona filifilia elemene fa'apolotini-chelated.
