Beta-Lactoglobulin (9045-23-2) Mwachidule

β-Lactoglobulin ndiye puloteni wamkulu wamkaka wamkaka ndi mkaka wa nkhosa (~ 3 g / l), ndipo amapezekanso m'mitundu ina yambiri ya abulu; chosangalatsa kukhala anthu. Pafupifupi 20% ya mapuloteni amkaka a bovine ndi mapuloteni amadzi, ndipo gawo lake lalikulu ndi beta-lactoglobulin. β-Lactoglobulin nthawi zambiri amakhala pophika mwa michere yama protein.

Mapuloteni amakoko amatha kukhala owopsa pakudya. Mkaka wa Bovine ndi imodzi mwazofunikira kwambiri pazakudya za allergenic, makamaka kwa ana. Zotsatira zake, kulembera kwa beta-lactoglobulin kapena mkaka ndizovomerezeka m'maiko ambiri. Ngakhale palibe malire azovomerezeka zamapuloteni a Whey, ndikofunikira kuti opanga zakudya azitha kuyesa zotsika kwambiri kuti ateteze anthu omwe samakonda komanso kupewa ziwonetsero za allergen.

Kodi Beta-Lactoglobulin ?

Beta-Lactoglobulin (ß-lactoglobulin, BLG) ndiye mapuloteni akuluakulu amkaka wowonekera ndipo amapezekanso mkaka wa nyama zina. Pafupifupi 20% ya mapuloteni amkaka a bovine ndi mapuloteni amadzi, ndipo gawo lake lalikulu ndi beta-lactoglobulin. Beta-Lactoglobulin nthawi zambiri amapanga kwambiri michere yama protein.

Beta-lactoglobulin ndi puloteni wapadziko lonse wa banja la lipocalin. Ili ndi kulemera kwa 18,300 ndipo imakhala ndi zotsalira 162 amino acid, kuphatikiza gawo lalikulu la nthambi za amino acid (BCAAs).

Beta-lactoglobulin (b-lactoglobulin / BLG) ndi imodzi mwazofunikira kwambiri mkaka wa ng'ombe. Ndi imodzi mwamapuloteni omwe amadziwika kwambiri mumkaka kupangitsa kuti thupi lawo lisagwire, ngakhale kuti anthu ambiri amasiyana ndi mitundu yambiri ya mkaka. BLG ndiye mapuloteni ochulukirapo kwambiri mu Whey, chifukwa 50% ya mapuloteni athunthu mu kachigawo ka lactoserum ndi pafupifupi 10% ya mkaka wa ng'ombe.

Mokulira, ma globulin ndi mapuloteni ang'onoang'ono omwe amapinda bwino, ndipo ma lactoglobulin ndi ma globulins amapezeka mkaka. Ngati casein amatsuka mkaka (mwachitsanzo, ndi rennet kapena acidity), ma lactoglobulins amakhalabe kumbuyo kwa Whey (limodzi ndi lactalbumin, lactose, mchere, ndi ma immunoglobulins). Mapuloteni ndi pafupifupi 10% ya zothetsera zowuma za Whey, ndipo beta-lactoglobulin ndi pafupifupi 65% ya 10% imeneyo.

Alfa-lactoglobulin amatenga nawo lactose synthesis. Cholinga cha beta-lactoglobulin sichimveka bwino, ndipo ngakhale chimatha kumanga mamolekyulu ambiri a hydrophobic, cholinga chake chachikulu ndikungokhala ngati gwero la amino acid. Beta-lactoglobulin yawonetsedwanso kuti ikhoza kumangiriza chitsulo kudzera m'makola am'mimba ndipo mwanjira imeneyi imatha kukhala ndi gawo polimbana ndi tizilombo toyambitsa matenda.

Beta-Lactoglobulin amapindula

Kukumana ndi mfundo yakuti Whey protein ndi osakaniza beta-lactoglobulin, alpha lactalbumin, bovine serum albin, ndi immunoglobin. Anthu ambiri amagwiritsa ntchito Whey monga supplementation, pambali yolimbana ndi masewera olimbitsa thupi, kuti athandize kusintha kaphatikizidwe ka minofu ndikulimbikitsa kukula kwa minofu yolonda.

Phindu lomwe mungakhale nalo limaphatikizapo kuchepetsa kunenepa, katundu wa anti-cancer, Kuchepetsa cholesterol, mphumu, kuthamanga kwa magazi ndi matenda amtima, Kuchepetsa kuchepa kwa anthu omwe ali ndi HIV.

Mosiyana ndi puloteni ina yayikulu ya Whey, α-lactalbumin, palibe chidziwitso chodziwikiratu chomwe chadziwika kwa β-lactoglobulin, izi ngakhale ndizofunikira kwambiri pakupanga mapuloteni apadziko lonse lapansi omwe amapatulidwa ndi Whey (β-lactoglobulin ≈⁠i65%, α-lactalbumin ≈⁠⁠ ⁠25%, serum albin ≈⁠⁠í8, ena ≈⁠i2%). β-lactoglobulin ndi mapuloteni a lipocalin, ndipo amatha kumanga mamolekyulu ambiri a hydrophobic, akuwonetsa udindo wawo pakuyendetsa. β-lactoglobulin yawonetsedwanso kuti ikhoza kumangiriza zitsulo kudzera mu siderophores ndipo motero imatha kukhala ndi gawo polimbana ndi tizilombo toyambitsa matenda. Mbiri ya kunyumba ya β-lactoglobulin ikusowa mkaka wa m'mawere wa anthu.

Beta-Lactoglobulin (BLG) ndiye mapuloteni ochulukitsitsa kwambiri mkaka wa bovine. LG yaphunziridwa kwambiri pamakampani azakudya chifukwa cha zopatsa thanzi komanso magwiridwe antchito pazinthu zosiyanasiyana zachilengedwe.

Kuphatikiza apo, BLG ikhoza kukhala mtengo wopanda antioxidant womwe umapezeka mosavuta komanso mosavuta. BLG itha kukhala ngati michere ya antioxidant yomwe imapezeka mosavuta komanso yotsika mtengo m'moyo watsiku ndi tsiku. Ripoti lathu lakale lidawonetsa kuti cysteine ​​yaulere ya BLG imagwira ntchito yoteteza mkaka wa antioxidant mkaka. BLG imayang'anira 50% ya ntchito ya antioxidant ya mkaka. Sikuti BLG imatha kuchita mwachindunji ngati michere ya antioxidant, imathanso kunyamula ma antioxidants ena kudzera m'thumba mwake lomangiriza. Chifukwa chake, zimawonjezera zonse ziwiri za bioavailability ndi kuchuluka kwa antioxidants omwe alipo.

β-Lactoglobulin ndiye puloteni wamkulu wamkaka wa bovine owerengera pafupifupi 50% ya mapuloteni mu Whey koma samapezeka mkaka wa munthu. β-Lactoglobulin imayambitsa magwiridwe antchito komanso opatsa thanzi zomwe zapangitsa kuti mapuloteniwa akhale zinthu zambiri zogwiritsidwa ntchito pophatikiza zakudya zambiri komanso mitundu yambiri.

Beta-Lactoglobulin mavuto

Beta-lactoglobulin (b-lactoglobulin / BLG) ndi imodzi mwazofunikira kwambiri mkaka wa ng'ombe. Ndi imodzi mwamapuloteni omwe amadziwika kwambiri mumkaka kupangitsa kuti thupi lawo lisagwire, ngakhale kuti anthu ambiri amasiyana ndi mitundu yambiri ya mkaka. BLG ndiye mapuloteni ochulukirapo kwambiri mu Whey, chifukwa 50% ya mapuloteni athunthu mu kachigawo ka lactoserum ndi pafupifupi 10% ya mkaka wa ng'ombe.

Beta-Lactoglobulin ufa ntchito

β-Lactoglobulin ndiye puloteni wamkulu wamkaka wa bovine owerengera pafupifupi 50% ya mapuloteni mu Whey koma samapezeka mkaka wa munthu. β-Lactoglobulin imayambitsa magwiridwe antchito komanso opatsa thanzi zomwe zapangitsa kuti mapuloteniwa akhale zinthu zambiri zogwiritsidwa ntchito pophatikiza zakudya zambiri komanso mitundu yambiri.
