Beta-Lactoglobulin (9045-23-2) Aotelega

β-Lactoglobulin o le sili whey porotini o povi ma susu susu (~ 3 g / l), ma o loʻo iai foi i le tele o isi mammalian ituaiga; o se ese ese mai ai o tagata. E tusa ma le 20% o polotini susu o povi o protein whey, faatasi ai ma le vaega autu o le beta-lactoglobulin. β-Lactoglobulin e masani ona avea ma autu elemeni i le whey-based protein powders.

E mafai ona avea ma aʻafiaga o mea taumafa meaai a le suka. O le susu susu o se tasi lea o meaʻai e sili ona taua i le allergenic, aemaise lava mo tamaiti. O le mea lea, o le faailogaina o le beta-lactoglobulin poʻo le susu e faʻamalosia i le tele o atunuu. E ui lava e leai se tapulaa o le tapulaa faaletulafono mo puipuiga o le uila, e matua fautuaina lava e suʻeina e le au gaosi mea taumafa meaai maualalo mo le puipuia o tagata mamaʻi ma aloese ai mai mea e aʻafia ai le mai.

O le a Beta-Lactoglobulin ?

Beta-Lactoglobulin (ß-lactoglobulin, BLG) o le tele o le porotini uila i le susu susu ma o loo i ai foi i totonu o le susu o isi meaola. E tusa ma le 20% o pulu vine e puipuia mai le susu, o mea ia e puipuia ai le uila, faatasi ai ma le vaega autu o le beta-lactoglobulin. O le Beta-Lactoglobulin e masani lava o le elemene autu i pulumu o le palatini.

Beta-lactoglobulin o se porotini globular o le lipocalin aiga. E i ai le mamafa mole mole o le 18,300 ma e aofia ai 162 amino acid residu, e aofia ai le maualuga maualuga o le faʻatapulaʻaina o filifili amino acid (BCAAs).

Beta-lactoglobulin (b-lactoglobulin / BLG) o se tasi o allergens matua i le susu susu. O se tasi lea o aʻafiaga sili ona taatele i le susu e mafua ai ni faʻafitauli o le maʻi, e ui lava o le toatele o tagata taitoatasi e masani ona afaina i le sili atu i le tasi le susu susu. BLG o le popo sili ona tele i le uila, faʻamaumauga mo le 50 pasene o le protein atoa i le vaega lactoserum ma e tusa ma le 10 pasene o susu susu.

O le mea lautele, o le globulins o ni fuatini laiti ia e gagau i luga o foliga, ma lactoglobulins o globulins o loʻo maua i le susu. A oʻo ina ave ese mai le susu mai le susu (mo se faʻataʻitaʻiga, e ala i le lafoaia poʻo le elemene), o le lactoglobulins o loʻo i tua i le uila (faatasi ai ma le lactalbumin, lactose, minerals, ma immunoglobulins). O penefiti e tusa ma le 10% o mea malogo o le uila, ma o le beta-lactoglobulin e tusa ma le 65% o lena 10%.

Alpha-lactoglobulin e aafia i le lactose synthesis. O le faamoemoega o le beta-lactoglobulin e le o manino, ma e ui lava e mafai ona fusifusia ai le tele o meaola ninii laiti, ae o le autu autu e ono avea ma punavai o mea amino. Beta-lactoglobulin ua faʻaalia foi e mafai ona uʻamea i luga o siderophores ma e ono i ai sona sao i le faʻafefeteina o pathogens.

Beta-Lactoglobulin aoga

Faʻafesagaʻi ma le mea moni o le Whey protein o se paluga o le beta-lactoglobulin, alpha lactalbumin, bovine serum albumin, ma immunoglobins. E masani ona faʻaaoga e tagata le whey e fai ma faʻaopopoga, faʻatasi ai ma le faʻamalosi tino, e faʻaleleia atili ai le maso polotini faʻalauteleina ma faʻalauteleina le tuputupu aʻe o maso maso maso.

Faʻamaumauga e ono mafai ona maua e aofia ai le fesoasoani i le faʻamagaloina o le tino, Fale o le kanesa, Faʻaitiitia o le cholesterol, Asthma, le toto ma le maʻi cardiovascular, Faʻaitiitia le mamafa o le mamafa i tagata e maua i le HIV.

Unlike the other main whey protein, α-lactalbumin, no clear function has been identified for β-lactoglobulin, this despite its being the biggest part of the fractional composition of the globular proteins isolated from whey (β-lactoglobulin ≈⁠ ⁠65%, α-lactalbumin ≈⁠⁠ ⁠25%, serum albumin ≈⁠⁠ ⁠8%, other ≈⁠ ⁠2%). β-lactoglobulin is a lipocalin protein, and can bind many hydrophobic molecules, suggesting a role in their transport. β-lactoglobulin has also been shown to be able to bind iron via siderophores and thus might have a role in combating pathogens. A homologue of β-lactoglobulin is lacking in human breast milk.

Beta-Lactoglobulin (BLG) o le sili atu lea o le porotini o le whey i le susu susu. O le LG na tele lava ina suʻesuʻeina i le faleoloa o mea taumafa ona o lona taumafa ma lona aoga i aafiaga eseese.

E le gata i lea, BLG atonu o se taugofie antioxidant nutrient e faigofie ma faigofie ona maua. E mafai e le BLG ona galue o se vailaʻau oʻona lelei e faigofie ona maua ma taugofie i aso uma. O le matou lipoti talu ai na faaalia ai o le leai o se cysteine ​​o le BLG e i ai sona sao i le puipuiga o le natura o le susu. O le BLG e gafa ma le 50% o gaioiga faʻamalosi tino a le susu. E le gata BLG mafai ona galue tuusaʻo o se antioxidant meaʻai, e mafai foi ona aveina isi antioxidants ala i le ligand fusi taga. O le mea lea, e faʻateleina uma bioavailability ma le aofaʻi o avanoa antioxidants.

β-Lactoglobulin o le tele lea o le porotini o le susu i le susu mo le tusa ma le 50% o protein i le uila ae e le maua i le susu o tagata. β-Lactoglobulin e maua ai le tele o mea aoga ma meaʻai paleni lea ua avea ai lenei polotini ma mea e faʻaaogaina tele mo le tele o meaʻai ma mea faʻapitoa.

 

Beta-Lactoglobulin itu aʻafiaga

Beta-lactoglobulin (b-lactoglobulin / BLG) o se tasi o allergens matua i le susu susu. O se tasi lea o aʻafiaga sili ona taatele i le susu e mafua ai ni faʻafitauli o le maʻi, e ui lava o le toatele o tagata taitoatasi e masani ona afaina i le sili atu i le tasi le susu susu. BLG o le popo sili ona tele i le uila, faʻamaumauga mo le 50 pasene o le protein atoa i le vaega lactoserum ma e tusa ma le 10 pasene o susu susu.

O faʻafitauli o se tali atu i le beta-lactoglobulin e mafai ona:

Lulu mumu po o sulu
