Kev sib raug zoo ntawm cov Proteins, Peptides, thiab Amino Acids
Cov Protein: Cov macromolecules ua haujlwm tau tsim los ntawm ib lossis ntau cov saw polypeptide uas sib dhos ua cov qauv peb-seem tshwj xeeb los ntawm cov helices, sheets, thiab lwm yam.
Cov saw polypeptide: Cov molecule zoo li saw uas muaj ob lossis ntau dua cov amino acids txuas nrog los ntawm peptide bonds.
Amino Acids: Cov khoom siv tseem ceeb ntawm cov protein; ntau tshaj 20 hom muaj nyob rau hauv xwm.
Hauv kev xaus, cov protein yog tsim los ntawm cov saw polypeptide, uas ua rau muaj cov amino acids.
Cov Txheej Txheem ntawm Kev Zom thiab Kev Nqus Protein hauv Cov Tsiaj
Kev Kho Mob Ua Ntej Hauv Qhov Ncauj: Cov khoom noj raug zom los ntawm kev zom hauv qhov ncauj, ua rau thaj chaw ntawm qhov chaw zom zaub mov ntau dua. Vim tias qhov ncauj tsis muaj cov enzymes zom zaub mov, cov kauj ruam no suav tias yog kev zom zaub mov siv tshuab.
Kev puas tsuaj ua ntej hauv lub plab:
Tom qab cov protein uas tawg lawm nkag mus rau hauv lub plab, cov kua qaub hauv plab ua rau lawv puas tsuaj, ua rau pom cov peptide bonds. Pepsin ces enzymatically rhuav cov protein ua cov polypeptides loj molecular, uas tom qab ntawd nkag mus rau hauv txoj hnyuv me.
Kev zom zaub mov hauv Txoj Hnyuv Me: Trypsin thiab chymotrypsin hauv txoj hnyuv me ntxiv rhuav cov polypeptides ua cov peptides me me (dipeptides lossis tripeptides) thiab cov amino acids. Cov no tom qab ntawd raug nqus mus rau hauv cov hlwb plab hnyuv ntawm cov amino acid thauj mus los lossis cov peptide thauj mus los me me.
Hauv kev noj zaub mov tsiaj, ob qho tib si protein-chelated trace elements thiab me me peptide-chelated trace elements txhim kho bioavailability ntawm trace elements los ntawm chelation, tab sis lawv txawv ntau hauv lawv cov txheej txheem nqus, kev ruaj khov, thiab cov xwm txheej siv tau. Cov hauv qab no muab kev tshuaj xyuas sib piv los ntawm plaub yam: mechanism nqus, cov yam ntxwv ntawm cov qauv, cov teebmeem ntawm kev siv, thiab cov xwm txheej tsim nyog.

Cov hlau ions tsim cov nplhaib chelates tsib lossis rau-membered ruaj khov dua nrog cov amino pawg, carboxyl pawg, thiab cov saw hlau sab. |
| Txoj Kev Nqus Tau | Yuav tsum tau siv cov proteases (piv txwv li, trypsin) hauv txoj hnyuv zom ua cov peptides me me lossis amino acids, thiab tso cov hlau ions chelated tawm. Cov ions no mam li nkag mus rau hauv cov ntshav los ntawm kev sib kis tsis tu ncua lossis kev thauj mus los ntawm cov ion channels (piv txwv li, DMT1, ZIP/ZnT transporters) ntawm cov hlwb epithelial hauv txoj hnyuv. | Yuav nqus tau ua cov chelates uas tsis muaj teeb meem ncaj qha los ntawm peptide transporter (PepT1) ntawm cov hlwb epithelial hauv plab hnyuv. Sab hauv lub cell, cov hlau ions raug tso tawm los ntawm cov enzymes hauv lub cell. |
| Cov kev txwv | Yog tias cov enzymes zom zaub mov tsis txaus (piv txwv li, rau cov tsiaj hluas lossis thaum muaj kev ntxhov siab), qhov ua tau zoo ntawm kev rhuav tshem cov protein tsawg. Qhov no yuav ua rau muaj kev cuam tshuam sai ntawm cov qauv chelate, ua rau cov hlau ions raug khi los ntawm cov yam tsis zoo rau kev noj haus xws li phytate, txo qis kev siv. | Tsis txhob cuam tshuam kev sib tw ntawm txoj hnyuv (piv txwv li, los ntawm phytic acid), thiab kev nqus tsis vam khom kev ua haujlwm ntawm cov enzyme zom zaub mov. Tshwj xeeb tshaj yog rau cov tsiaj hluas uas tsis tau loj hlob lossis cov tsiaj mob/tsis muaj zog. |

| Lub zog ntawm Chelate Bond | Ntau qhov kev sib txuas ua ke, tab sis kev hloov pauv molecular nyuaj ua rau muaj kev ruaj khov nruab nrab. | Kev tsim cov peptide luv luv yooj yim tso cai rau kev tsim cov qauv nplhaib ruaj khov dua. |
| Kev Tiv Thaiv Kev Cuam Tshuam | Yooj yim cuam tshuam los ntawm cov kua qaub hauv plab thiab kev hloov pauv ntawm pH hauv plab hnyuv. | Muaj zog tiv taus cov kua qaub thiab alkali; kev ruaj khov dua hauv ib puag ncig plab hnyuv. |
3. Cov teebmeem ntawm daim ntawv thov:
| Qhov Qhia | Cov Protein Chelates | Cov Peptide Chelates Me Me |
|---|---|---|
| Kev siv tau ntawm lub cev | Nyob ntawm seb cov enzyme zom zaub mov ua haujlwm li cas. Zoo rau cov tsiaj laus uas noj qab nyob zoo, tab sis kev ua haujlwm yuav txo qis ntau rau cov tsiaj hluas lossis cov tsiaj ntxhov siab. | Vim yog txoj kev nqus ncaj qha thiab cov qauv ruaj khov, kev siv tau cov khoom me me yog 10% ~ 30% siab dua li ntawm cov protein chelates. |
| Kev Nthuav Dav ntawm Kev Ua Haujlwm | Kev ua haujlwm tsis zoo, feem ntau yog ua cov khoom thauj kab. | Cov peptides me me lawv tus kheej muaj cov haujlwm xws li kev tswj hwm kev tiv thaiv kab mob thiab kev ua haujlwm antioxidant, muab cov teebmeem synergistic muaj zog dua nrog cov ntsiab lus me me (piv txwv li, Selenomethionine peptide muab ob qho tib si selenium ntxiv thiab antioxidant ua haujlwm). |
4. Cov Xwm Txheej Tsim Nyog thiab Kev Xav Txog Kev Lag Luam:
