Tlhatlhobo ea Beta-Lactoglobulin (9045-23-2)

β-Lactoglobulin ke protheine e kholo ea Whey ea lebese la khomo le nku (~ 3 g / l), hape e teng mefuteng e meng e mengata ea mammalian; mokhelo o hlokomelehang ke batho. Hoo e ka bang 20% ​​ea liprotheine tsa lebese la likhomo ke liprotheine tsa Whey, 'me karolo ea eona e kholo ke beta-lactoglobulin. β-Lactoglobulin hangata ke sesebelisoa sa mantlha sa li-Wheel-based protein powders.

Liprotheine tse Whey e ka ba li-alleranti tse kotsi tsa lijo. Lebese la Bovine ke e 'ngoe ea lintho tsa bohlokoa ka ho fetisisa tse amanang le lijo tsa allergen, haholo bakeng sa bana. Ka lebaka leo, ho ngolloa ha beta-lactoglobulin kapa lebese hoa hlokahala linaheng tse ngata. Le ha ho se na meeli ea molao bakeng sa liprotheine tsa Whey, ho khothalletsoa haholo hore baetsi ba lijo ba leke liteko tse tlase haholo ho sireletsa batho ba kulang le ho qoba ho hopoloa ho amanang le allergen.

ke eng Beta-Lactoglobulin ?

Beta-Lactoglobulin (ß-lactoglobulin, BLG) ke protheine e kholo ea lebese le lebeseng 'me e teng le lebeseng la liphoofolo tse ling. Hoo e ka bang 20% ​​ea liprotheine tsa lebese tsa bovine ke liprotheine tsa Whey, mme karolo ea mantlha e le beta-lactoglobulin. Beta-Lactoglobulin hangata ke eona motsoako o ka sehloohong metsong ea liprotheine e entsoeng ka Whey.

Beta-lactoglobulin ke protheine ea globular ea lelapa la lipocalin. E na le boima ba limolek'hule tse 18,300 'me e na le masala a 162 a amino acid, ho kenyeletsoa le karolo e batlang e phahame ea li-amino acid (BCAAs) tse nang le branched.

Beta-lactoglobulin (b-lactoglobulin / BLG) ke e 'ngoe ea lintho tse ka sehloohong tse kulang ka bongata lebeseng la khomo. Ke e 'ngoe ea liprotheine tse tloaelehileng ka ho fetisisa lebeseng ho baka lintho tse kulang, le ha ho le joalo batho ba bangata ba kulisa liprotheine tse ngata tsa lebese. BLG ke protheine e ngata ka ho fetisisa ho Whey, e nka karolo ea 50 lekholong ea protheine e felletseng ka karoloana ea lactoserum le liperesente tse 10 tsa lebese la khomo.

Ka kakaretso, li-globulin ke liprotheine tse nyane tse ikatisang, ebe li-lactoglobulin ke li-globulin tse teng lebeseng. Ha casein e tlosoa ka lebese (mohlala, ka rennet kapa acidity), lactoglobulins e sala e le ka morao ho Whey (hammoho le lactalbumin, lactose, liminerale le immunoglobulins). Liprotheine li ka bang 10% ea mongobo o ommeng oa Whey, 'me beta-lactoglobulin ke hoo e ka bang 65% ea 10% eo.

Alpha-lactoglobulin e kenella ho lactose synthesis. Morero oa beta-lactoglobulin ha o hlakile, mme leha o ka kopanya limolek'hule tse ngata tse nyane tsa hydrophobic, sepheo sa mantlha e kanna ea ba ho sebetsa e le mohloli oa li-amino acid. Beta-lactoglobulin le eona e bontšitsoe hore e khona ho tlama tšepe ka siderophores, ka hona e ka ba le karolo ho loants'eng likokoana-hloko.

Melemo ea Beta-Lactoglobulin

Ho tobana le taba ea hore Whey protein ke motsoako oa beta-lactoglobulin, alpha lactalbumin, bovine serum albumin, le immunoglobins. Batho ba tloaetse ho sebelisa Whey e le tlatsetso, hammoho le boikoetliso ba ho hanyetsa, ho thusa ho ntlafatsa protheine ea mesifa le ho khothaletsa kholo ea mesifa e boima.

Melemo e ka bang teng e kenyelletsa ho thusa ho theola boima ba 'mele, thepa ea anti-cancer, cholesterol e fokotsang, asthma, khatello ea mali le lefu la pelo, ho fokotsa boima ba' mele bathong ba nang le HIV.

Ho fapana le protheine e 'ngoe e kholo ea Whey, α-lactalbumin, ha ho na ts'ebetso e hlakileng e fumanoeng bakeng sa β-lactoglobulin, sena leha e le karolo e kholo ea likaroloana tsa liprotheine tsa globular tse arohaneng le whey (β-lactoglobulin ≈⁠ ⁠65%, α-lactalbumin ≈⁠ ⁠25%, serum albumin ≈⁠⁠8%, tse ling ≈⁠2%). β-lactoglobulin ke protheine ea lipocalin, 'me e ka tlama limolek'hule tse ngata tsa hydrophobic, e fana ka maikutlo a karolo ea lipalangoang tsa tsona. β-lactoglobulin e boetse e bontšitsoe e khona ho tlama tšepe ka li-siderophores mme ka hona e ka ba le karolo ho loantseng likokoana-hloko. Homologue ea β-lactoglobulin e haelloa ke lebese la motho.

Beta-Lactoglobulin (BLG) ke protheine e ngata ka ho fetisisa lebese lebeseng la bovine. LG e ithutile haholo indastering ea lijo ka lebaka la phepo ea eona e nepahetseng le ts'ebetso ea eona lits'ebetsong tse fapaneng tsa bioloji.

Ntle le moo, BLG e kanna ea ba phepo e theko e tlaase ea antioxidant e fumanehang habonolo le habonolo. BLG e kanna ea sebetsa e le phepo ea antioxidant e fumanehang habonolo ebile e theko e tlase bophelong ba letsatsi le letsatsi. Tlaleho ea rona ea pejana e bontšitse hore cysteine ​​ea mahala ea BLG e bapala karolo ea tšireletso ho antioxidant ea lebese. BLG e ikarabella bakeng sa karolo ea 50% ea tšebetso ea antioxidant ea lebese. Hase feela hore BLG e ka sebetsa ka kotloloho e le phepo ea antioxidant, hape e ka jara li-antioxidants tse ling ka pokothong ea eona ea ligand. Kahoo, e eketsa bioavailability le bongata ba li-antioxidants tse fumanehang.

β-Lactoglobulin ke protheine e kholo ea lebese ka har'a bovine e nang le liprotheine tse ka bang 50% ho Whey empa ha e fumanehe lebeseng la motho. β-Lactoglobulin e hlahisa mefuta e fapaneng ea ts'ebetso le phepo e nepahetseng e entseng hore protheine ena e be lisebelisoa tse kopaneng tsa lijo le lisebelisoa tse ngata tsa biochemical.

 

Beta-Lactoglobulin litla-morao

Beta-lactoglobulin (b-lactoglobulin / BLG) ke e 'ngoe ea lintho tse ka sehloohong tse kulang ka bongata lebeseng la khomo. Ke e 'ngoe ea liprotheine tse tloaelehileng ka ho fetisisa lebeseng ho baka lintho tse kulang, le ha ho le joalo batho ba bangata ba kulisa liprotheine tse ngata tsa lebese. BLG ke protheine e ngata ka ho fetisisa ho Whey, e nka karolo ea 50 lekholong ea protheine e felletseng ka karoloana ea lactoserum le liperesente tse 10 tsa lebese la khomo.
