IBeta-Lactoglobulin (9045-23-2) Isishwankathelo

I-act-Lactoglobulin yeyona protheyini iphambili yobisi lweenkomo kunye nobisi lweegusha (~ 3 g / l), kwaye ikwakhona nakwezinye iintlobo ezininzi zezilwanyana ezanyisayo; into ephawulekayo ngaphandle kwabantu. Malunga neepesenti ezingama-20 zeeproteni zobisi lweenkomo zii-whey protein, kunye neyona nto iphambili kuyo yi-beta-lactoglobulin. I-act-Lactoglobulin ihlala isisithako esiphambili kwiipowder ze-Whey-based powders.

Iiprotheyini ezinamavili zinokuba yingozi ekutyeni komzimba Ubisi lweBovine yenye yezona zinto zibalulekileyo ze allergenic zokutya, ngakumbi abantwana. Ngenxa yoko, ukubhalwa kwe-beta-lactoglobulin okanye ubisi kunyanzelekile kumazwe amaninzi. Nangona kungekho mqobo uthintelayo osemthethweni weprotey ye-Whey, kucetyiswa kakhulu ukuba abavelisi bokutya bavavanye ukugxila okuncinci kakhulu ukukhusela abantu abangadibaniyo nokuphepha ukukhumbula okuhambelana ne-allergen.

Yintoni i IBeta-Lactoglobulin ?

IBeta-Lactoglobulin (ß-lactoglobulin, BLG) yiproteyini enkulu kubisi olufumileyo kwaye ikwakhona kubisi lwezinye izilwanyana. Malunga neepesenti ezingama-20 zeeproteni zobisi lwe-bovine ziiprotein ezinamavili, ezona zinto ziphambili zibizwa ngokuba yi-beta-lactoglobulin. IBeta-Lactoglobulin ihlala iyeyona nto iphambili kwii-powyers zeprotheyini esekwe kwi-Whey.

I-Beta-lactoglobulin yiprotein ye-globular yosapho lwe-lipocalin. Inobunzima beemolekyuli eziyi-18,300 kwaye inezintsalela ze-amino acid eziyi-162, kubandakanya nenani eliphezulu kakhulu le-amino acid (BCAAs).

IBeta-lactoglobulin (b-lactoglobulin / BLG) yenye yezona zinto zibaluleke kakhulu kubisi lwenkomo. Ngenye yeeprotheyini ezixhaphakileyo kubisi ukubangela ukungalunganga, nangona abantu abaninzi bengafani nezinye iiproteyini zobisi ezingaphezu kwesinye. I-BlG yeyona proteni ininzi kwi-Whey, ibala iipesenti ezingama-50 yeprotheyini epheleleyo kwiqhezu le-lactoserum kunye neepesenti ezili-10 zobisi lwenkomo.

Ngokubanzi, iiglobulin ziiproteni ezincinci ezisongelayo zaye zayindawo ebanzi, kwaye i-lactoglobulins zii-globulins ezikhoyo kubisi. Xa i-kesiin icinywe ngaphandle kobisi (umzekelo, nge-rennet okanye i-acidity), i-lactoglobulins isala ngasemva kwi-Whey (kunye ne-lactalbumin, i-lactose, iiminerali kunye ne-immunoglobulins). Iiprotheyini zimalunga ne-10% yolwelo olomileyo lwe-Whey, kwaye i-beta-lactoglobulin imalunga ne-65% yelo 10%.

I-Alpha-lactoglobulin ibandakanyeka kwi-lactose synthesis. Injongo ye-beta-lactoglobulin ayicacanga, kwaye nangona inokubopha ii-molekyuli ezininzi ezincinci ze-hydrophobic, eyona njongo iphambili kunokukwenza njengomthombo we-amino acid. IBeta-lactoglobulin ikwabonakalisiwe ukuba ikwazi ukubopha i-iron siderophores kwaye ke ngoko inokuba nendima ekulweni iintsholongwane.

Izibonelelo zeBeta-Lactoglobulin

Ukujongana nenyaniso yokuba Whey protein ngumxube we-beta-lactoglobulin, i-alpha lactalbumin, i-bovine serum albumin, kunye nee-immunoglobins. Abantu bahlala besebenzisa i-whey njengoncediso, kunye nokuxhathisa umthambo, ukunceda ukuphucula iiprotein zemisipha kunye nokukhuthaza ukukhula kobunzima bemisipha.

Izibonelelo ezinokubakho zokunceda ukunciphisa umzimba, iipropathi ezichasene nomhlaza, Ukuthoba i-cholesterol, isifo se-asthma, uxinzelelo lwegazi kunye nesifo sentliziyo, ukunciphisa ukunciphisa umzimba kubantu abane-HIV.

Ngokungafaniyo nezinye iiprotheyini eziphambili ze-whey, i-α-lactalbumin, akukho msebenzi ucacileyo uchongiwe we-β-lactoglobulin, oku ngaphandle kokuba yeyona nxalenye inkulu yenxalenye yeeproteni zeglobular ezizimeleyo kwi-whey (β-lactoglobulin ≈⁠ ⁠65%, I-α-lactalbumin 25⁠⁠ 8%, i-albhamu ye-serum ≈⁠⁠ ye-2%, enye i-≈⁠XNUMX%). I-lact-lactoglobulin yiprotini ye-lipocalin, kwaye inokubopha iimolekyuli ezininzi ze-hydrophobic, iphakamisa indima kwezothutho. I-lact-lactoglobulin ikwabonakalise ukuba iyakwazi ukubopha i-iron ngokusebenzisa i-siderophores kwaye ke inokuba nenxaxheba ekulweni iintsholongwane. I-homologue ye-β-lactoglobulin iyasilela kubisi lwebele lomntu.

IBeta-Lactoglobulin (BLG) yeyona proteni ininzi yevili kubisi lwe-bovine. I-LG ifundwe ngokubanzi kwishishini lokutya ngenxa yesondlo sayo kunye nokusebenza kwayo kwiinkqubo ezahlukeneyo zebhayiloji.

Ukongeza, i-BLG inokuba sisondlo esinexabiso eliphantsi se-antioxidant esifumaneka ngokulula nangokulula. I-BLG inokuthi isebenze njengesondlo se-antioxidant esifikeleleka ngokulula kwaye sitshiphu kubomi bemihla ngemihla. Ingxelo yethu yangaphambili ibonise ukuba i-cysteine ​​yasimahla ye-BLG idlala indima ekhuselayo kwimeko yobisi ye-antioxidant. I-BLG inoxanduva lwe-50% yomsebenzi wobisi we-antioxidant. Ayisiyiyo kuphela i-BLG esebenza ngokuthe ngqo njengesondlo se-antioxidant, ikwanokuthwala ezinye i-antioxidants nge-ligand yayo ebophayo. Yiyo loo nto inyusa ukubakho kokufumaneka kunye nenani lee-antioxidants ezikhoyo.

I-ac-Lactoglobulin yiprotey enkulu kwi-bovine yobisi icacisa i-50% yeeproteni kwi-Whey kodwa ayifumaneki kubisi lomntu. I-ac-Lactoglobulin ibeka izinto ezahlukeneyo ezisebenzayo kunye nezesondlo ezenze ukuba le proteni ibe yinto ehambelana nezinto ezininzi ekutyeni nasekusebenziseni izinto eziphilayo.

 

Iziphumo zeziphumo zeBeta-Lactoglobulin

IBeta-lactoglobulin (b-lactoglobulin / BLG) yenye yezona zinto zibaluleke kakhulu kubisi lwenkomo. Ngenye yeeprotheyini ezixhaphakileyo kubisi ukubangela ukungalunganga, nangona abantu abaninzi bengafani nezinye iiproteyini zobisi ezingaphezu kwesinye. I-BlG yeyona proteni ininzi kwi-Whey, ibala iipesenti ezingama-50 yeprotheyini epheleleyo kwiqhezu le-lactoserum kunye neepesenti ezili-10 zobisi lwenkomo.
