Ubudlelwane phakathi kweeProteni, iiPeptides, kunye neeAmino Acids
Iiproteni: Iimacromolecule ezisebenzayo ezenziwe yitsheyini enye okanye ezingaphezulu zepolypeptide ezisongwayo zibe zizakhiwo ezithile ezinemilinganiselo emithathu ngokusebenzisa iihelices, amaphepha, njl.njl.
Iintambo zePolypeptide: Iimolekyuli ezifana ne-chain ezenziwe zii-amino acid ezimbini okanye ngaphezulu ezidityaniswe ziibhondi ze-peptide.
Ii-Amino Acids: Zizinto ezisisiseko zokwakha iiproteni; kukho iintlobo ezingaphezu kwama-20 kwindalo.
Ngamafutshane, iiproteni zenziwe ngamaketanga e-polypeptide, wona enziwe ngama-amino acid.
Inkqubo Yokugaya Iiproteni Nokufunxwa Kwezilwanyana
Unyango Lomlomo Ngaphambi Kokutya: Ukutya kuyaphulwa ngokwasemzimbeni ngokuhlafuna emlonyeni, nto leyo eyandisa indawo yomphezulu wokugaya ukutya okune-enzyme. Njengoko umlomo ungenazo ii-enzyme zokugaya ukutya, eli nyathelo lithathwa njengokugaya ukutya okune-mechanical.
Ukwaphuka Kwangaphambili Kwesisu:
Emva kokuba iiproteni eziqhekekileyo zingene esiswini, i-asidi yesisu iyayisusa, iveze ii-peptide bonds. Emva koko i-Pepsin yahlula iiproteni nge-enzymatic ibe zii-polypeptide ezinkulu ze-molecular, ezithi emva koko zingene emathunjini amancinci.
Ukugaya ukutya kwiMathumbu Amancinci: I-Trypsin kunye ne-chymotrypsin emathunjini amancinci ziqhekeza ngakumbi ii-polypeptides zibe zii-peptides ezincinci (ii-dipeptides okanye ii-tripeptides) kunye nee-amino acids. Ezi emva koko zifunxwa kwiiseli zamathumbu ngeenkqubo zokuthutha ii-amino acid okanye inkqubo yokuthutha ii-peptides ezincinci.
Kwisondlo sezilwanyana, zombini izinto ezilandelelanayo ezineproteni kunye nezinto ezincinci ezilandelelanayo ezinepeptidi ziphucula ukufumaneka kwezinto ezilandelelanayo nge-chelation, kodwa zahlukile kakhulu kwindlela yazo yokufunxa, uzinzo, kunye neemeko ezifanelekileyo. Oku kulandelayo kubonelela ngohlalutyo oluthelekisayo oluvela kwiinkalo ezine: indlela yokufunxa, iimpawu zesakhiwo, iziphumo zokusetyenziswa, kunye neemeko ezifanelekileyo.
1. Indlela yokufunxa:
| Isalathisi sokuthelekisa | Izinto ezilandelelanayo ezineeproteni | Izinto ezincinci zeTrace ezinePeptide-chelated |
|---|---|---|
| Inkcazo | IiChelates zisebenzisa iiproteni ze-macromolecular (umz., iiproteni zezityalo ezifakwe i-hydrolyzed, iiproteni ze-whey) njengezithwali. Ii-ion zesinyithi (umz., i-Fe²⁺, i-Zn²⁺) zenza iibhondi ezidibeneyo kunye namaqela e-carboxyl (-COOH) kunye nee-amino (-NH₂) zee-amino acid residues. | Isebenzisa iipeptides ezincinci (ezenziwe ngee-amino acids ezi-2-3) njengezithwali. Ii-ion zesinyithi zenza ii-ring chelates ezizinzileyo ezinamalungu amahlanu okanye amathandathu kunye namaqela e-amino, amaqela e-carboxyl, kunye namaqela e-side chain. |
| Indlela yokufunxa | Zifuna ukuqhekeka ziiprotease (umz., i-trypsin) emathunjini zibe ziipeptides ezincinci okanye ii-amino acids, zikhuphe ii-ion zesinyithi ezityheli. Ezi ions emva koko zingena egazini nge-passive diffusion okanye nge-active transport ngokusebenzisa ii-ion channels (umz., i-DMT1, ii-ZIP/ZnT transporters) kwiiseli ze-epithelial zamathumbu. | Ingafunxwa njengee-chelates ezipheleleyo ngokuthe ngqo nge-peptide transporter (PepT1) kwiiseli ze-epithelial zamathumbu. Ngaphakathi kwiseli, ii-ion zesinyithi zikhutshwa zii-enzymes zangaphakathi kwiseli. |
| Imida | Ukuba umsebenzi wee-enzymes zokugaya ukutya awanelanga (umz., kwizilwanyana ezincinci okanye phantsi koxinzelelo), ukusebenza kakuhle kokuqhekeka kweeproteni kuphantsi. Oku kunokukhokelela ekuphazamisekeni kwangaphambi kwexesha kwesakhiwo se-chelate, okuvumela ii-ion zesinyithi ukuba zibotshelelwe zizinto ezichasene nesondlo ezifana ne-phytate, nto leyo enciphisa ukusetyenziswa. | Idlula ekuthinteleni ukhuphiswano lwamathumbu (umz., kwi-phytic acid), kwaye ukufunxwa akuxhomekanga kumsebenzi we-enzyme yokugaya. Ifanelekile ngakumbi kwizilwanyana eziselula ezineenkqubo zokugaya ezingavuthwanga okanye izilwanyana ezigulayo/ezibuthathaka. |
2. Iimpawu zoBume kunye noZinzo:
| Uphawu | Izinto ezilandelelanayo ezineeproteni | Izinto ezincinci zeTrace ezinePeptide-chelated |
|---|---|---|
| Ubunzima beMolekyuli | Enkulu (5,000~20,000 Da) | Encinci (200~500 Da) |
| Amandla eBond yeChelate | Iibhondi ezininzi ezilungelelanisiweyo, kodwa ukwakheka kweemolekyuli ezintsonkothileyo kukhokelela ekuzinzeni okuphakathi ngokubanzi. | Ukwakheka kwepeptide emfutshane elula kuvumela ukwakheka kwezakhiwo zeringi ezizinzileyo ngakumbi. |
| Amandla okuchasa ukuphazamiseka | Ichaphazeleka yi-asidi yesisu kunye nokuguquguquka kwe-pH yamathumbu. | Ukumelana ne-asidi enamandla kunye ne-alkali; uzinzo oluphezulu kwindawo yamathumbu. |
3. Iziphumo zokusetyenziswa:
| Isalathisi | Iiprotein Chelates | IiChelates zePeptide ezincinci |
|---|---|---|
| Ukufumaneka kwezinto eziphilayo | Ixhomekeke kumsebenzi wee-enzyme zokugaya ukutya. Isebenza kakuhle kwizilwanyana ezindala ezisempilweni, kodwa ukusebenza kwayo kuncipha kakhulu kwizilwanyana eziselula okanye ezixinezelekileyo. | Ngenxa yendlela yokufunxa ngokuthe ngqo kunye nolwakhiwo oluzinzileyo, ukufumaneka kwezinto ezilandelelanayo kuphezulu nge-10% ~ 30% kunee-protein chelates. |
| Ukwandiswa kokusebenza | Ukusebenza okubuthathaka kakhulu, ikakhulu kusebenza njengezinto ezithwala izinto ezincinci. | Iipeptides ezincinci ngokwazo zinemisebenzi efana nokulawula amasosha omzimba kunye nomsebenzi we-antioxidant, zibonelela ngemiphumo enamandla yokusebenzisana kunye nezinto ezilandelelanayo (umz., i-Selenomethionine peptide inika zombini imisebenzi yokongeza i-selenium kunye ne-antioxidant). |
4. Iimeko ezifanelekileyo kunye nezinto eziqwalaselwayo kwezoqoqosho:
| Isalathisi | Izinto ezilandelelanayo ezineeproteni | Izinto ezincinci zeTrace ezinePeptide-chelated |
|---|---|---|
| Izilwanyana Ezifanelekileyo | Izilwanyana ezindala ezisempilweni (umz., iihagu ezigqibileyo, iinkukhu ezizalelayo) | Izilwanyana ezincinci, izilwanyana eziphantsi koxinzelelo, iintlobo zasemanzini ezivelisa kakhulu |
| Ixabiso | Ezantsi (izinto eziluhlaza ziyafumaneka lula, inkqubo elula) | Ixabiso eliphezulu (ixabiso eliphezulu lokwenziwa kwe-peptide encinci kunye nokuhlanjululwa) |
| Impembelelo kwiNdalo | Iindawo ezingafunxwanga zinokuphuma kwindle, nto leyo enokonakalisa okusingqongileyo. | Izinga lokusetyenziswa eliphezulu, umngcipheko ophantsi wongcoliseko lokusingqongileyo. |
Isishwankathelo:
(1) Kwizilwanyana ezineemfuno eziphezulu zezinto ezilandelelanayo kunye namandla okugaya abuthathaka (umz., amantshontsho eehagu, amantshontsho, izibungu ze-shrimp), okanye izilwanyana ezifuna ukulungiswa ngokukhawuleza kweentsilelo, ii-chelates ezincinci ze-peptide ziyacetyiswa njengokhetho oluphambili.
(2) Kumaqela axabisa kakhulu anomsebenzi oqhelekileyo wokugaya ukutya (umz., imfuyo kunye neenkukhu ezikwinqanaba lokugqibela), izinto ezilandelanayo ezineeproteni zinokukhethwa.
