Casein phosphopeptides (CPP) imhando yezvishandiso zvekuwedzera zvekudya
Casein phosphopeptide inonzi casein hydrolyzed ne trypsin kana trypsin, iyo inonatswa nekucheneswa. Chimiro chayo chikuru ndiSer (P) - Ser (P) - Ser (P) - Glu Glu - (Ser: serine, Glu: glutamic acid, P: phosphate). Iyo phosphoserine residues (- Ser (P) -) muchimiro ichi iripo mumasumbu uye inotakura mhosva dzisina kunaka mune isina simba alkaline pH mamiriro emukati, ayo anogona kudzivirira kumwe kuita kwema enzymes ekugaya uye kudzivirira CPP kubva pakuwedzera hydrolysis, zvichikonzera kuvepo kwakasimba. muura. Tsvagiridzo yemumba yakawana kuti iyo diki molar ratio ye nitrogen kune phosphorus muCPP, iyo ipfupi peptide cheni yeCPP, uye yakakwira density yemapoka ephosphate, zvichikonzera kuchena kweCPP uye kusimudzirwa kwakasimba kwekutorwa kwecalcium nekushandiswa.
Calcium inotorwa nyore nyore chete kana iripo muchimiro cheiyoni, uye munzvimbo dzisina kwazvakarerekera uye dzisina kusimba alkaline, zviri nyore kugadzira munyu usinganyungudika neasidhi ions uye kurasika. Kutora kweCPP pa calcium kunonyanya kuratidzwa nekugona kwayo kusunga ne calcium munzvimbo dzisina kwazvakarerekera uye dzisina kusimba alkaline, inhibisa chizvarwa cheinsoluble precipitates, kudzivirira kurasikirwa kwekarusiyamu, uye pakupedzisira kunyura zvishoma nekuda kwekuwedzera kwemahara calcium concentration. Tsvagiridzo yazvino inoratidza kuti mhedzisiro yeCPP pakusimudzira kunyura kwe calcium inonyanya kuratidzwa mune zvinotevera zvinhu:
- (1) Kurudzira kutorwa kwecalcium muura hudiki.
Zvokudya zvezviyo zviri mukudya kwevanhu zvine huwandu hwakawanda hwezvinhu zvakakura zve phosphorus zvakadai se phytic acid uye inositol hexaphosphate, iyo inosanganiswa ne calcium mu pH 7-8 nharaunda pamucheto wezasi wehuku hudiki kuti iite calcium phosphate precipitates. CPP inogona kurambidza kuumbwa kwecalcium phosphate precipitation, kuchengetedza yakakwira yemahara calcium, inosimudzira passive kutorwa kwecalcium, uye kuva imwe nzira yevhitamini D seanosimudzira calcium absorption.
- (2) Kurudzira kushandiswa kwecalcium nemapfupa.
Kuedza kwemhuka kunoratidza kuti CPP inogona kukurudzira kutora uye kushandiswa kwecalcium, kuderedza mhedzisiro ye osteoclast uye inhibit bone resorption.
- (3) Kurudzira kushandiswa kwecalcium nemazino.
Kare, zvaitendwa kuti kutsenga chizi mushure mekudya kunogona kuita kuti mate abude, zvichiita kuti mate ane alkaline avhare zvinhu zvine acidic pamazino plaque kubva mukuora enamel, iyo inobatsira kudzivirira kuitika kwemazino. Mumakore achangopfuura, tsvakiridzo yakawana kuti CPP iri muchizi inogona kusunga calcium ions muchikafu kune mazino caries, kuderedza enamel demineralization, uye nekudaro kuzadzisa zvinangwa zveanti caries.
Tsvagiridzo yakawana kuti sperm mune yetsika svikiro ine CPP ine yakanyanya kukwirira kugona kupinda mumasero ezai uye inogona kuderedza dhigirii rekusiyana kwembeu, zvichiita kuti kukura kwe embryonic kugadzikane. CPP inogona zvakare kuvandudza bioavailability yesimbi ions senge iron, zinc, uye magnesium, nekudaro inozivikanwa sechinhu chepeptide chine simbi inotakura basa. Parizvino, CPP yakaiswa muvana curry mupunga, zvinwiwa, chewing gum uye zvimwe zvekudya uye zvigadzirwa zvehutano kunze kwenyika. Tsvagiridzo uye mashandisirwo ekurapa kushomeka kwecalcium muvana, osteoporosis kune vakwegura, kushaya mbereko, uye hutano hwemazino zviri kuenderera mberi. Nekuti CPP iri peptide yakatorwa kubva kumapuroteni echisikigo uye ine mabhenefiti ekuita kushoma kwakashata, kuchengetedzeka, uye kuvimbika, ichashandiswa zvakanyanya. Iyo sensitization reaction yecasein, skim mukaka protein uye CPP yakadzidzwa kunze kwenyika, uye zvakaonekwa kuti sensitization yeCPP idiki kwazvo, zvichiratidza kuti inogona kushandiswa kune bumbiro remagetsi allergic kumukaka. Nekudaro, zvinofanirwa kucherechedzwa kuti izvo zvinokanganisa mhedzisiro yeCPP yakaoma kwazvo, uye basa ravo mu calcium metabolism richiri kuda kuvandudzwa.
