Beta-Lactoglobulin (9045-23-2) Kuongorora

β-Lactoglobulin ndiyo yakakosha mapuroteni emukaka wemombe nemakwai (~ 3 g / l), uye irimo mune mamwe akawanda mammalian marudzi; chakasarudzika kusarudzika kuve vanhu. Inenge makumi maviri muzana% yemapuroteni emukaka wemombe ane mapuroteni, ane chikamu chikuru chiri beta-lactoglobulin. β-Lactoglobulin inowanzo kuve chinhu chikuru mumavhiri-based protein mapoda.

Whey mapuroteni anogona kuva nengozi chikafu allergens. Bovine mukaka ndeimwe yeakanakisa allergenic chikafu hanyanisi, kunyanya kuvana. Nekuda kweizvozvo, kudhindwa kweb beta-lactoglobulin kana mukaka kunomanikidzwa mune dzakawanda nyika. Kunyangwe hazvo pasina miganhu yepamutemo yeiyo Whey mapuroteni, zvinokurudzirwa zvakanyanya kuti vagadziri vekudya vayedze zvakanyanya kuderera kuchengetedza vanhu vane allergen uye vadzivise zvine allergen zvine hukama.

Chii Beta-Lactoglobulin ?

Beta-Lactoglobulin (ß-lactoglobulin, BLG) ndiyo yakakura Whey protein mumukaka wakasviba uye iripo mumukaka wedzimwe mhuka. Anenge makumi maviri muzana emapuroteni emukaka anonzi bovine mapuroteni ane Whey, uye chinhu chikuru ichi chiri beta-lactoglobulin. Beta-Lactoglobulin kazhinji ndiyo inonyanya kugadzirwa mune Whey-based protein protein.

Beta-lactoglobulin ipuroteni yepasi rose yemhuri yemalocalin. Iyo ine mamorekuru uremu hwe18,300 uye ine 162 amino acid masara, kusanganisira yakaenzana chikamu chakakura chebranched-chain amino acids (BCAAs).

Beta-lactoglobulin (b-lactoglobulin / BLG) ndomumwe wemaronda makuru mumukaka wemombe. Iyo ndeimwe yemapuroteni akajairwa mumukaka kukonzera mhedzisiro, asi vanhu vazhinji vanowanzokanganiswa nemaprotein mazhinji emukaka. BLG ndiyo yakawanda protein yakawanda mu Whey, inoverengera makumi mashanu muzana yeprotein yakazara mu lactoserum chidimbu uye inenge gumi muzana yemukaka wemombe.

Kazhinji, ma globulin mapuroteni mashoma anopinda mune akaomarara, uye lactoglobulins ari ma globulins aripo mumukaka. Kana kesiinin yakarongedzwa kunze kwemukaka (semuenzaniso, ne rennet kana acidity), lactoglobulins inosara kumashure mu Whey (pamwe ne lactalbumin, lactose, mineral, uye immunoglobulins). Mapuroteni anenge gumi muzana ezvemagetsi akaomesesa eiyo Whey, uye beta-lactoglobulin inenge 10% yeiyo 65%.

Alfa-lactoglobulin inobatanidzwa mu lactose synthesis. Chinangwa che beta-lactoglobulin hachina kujeka, uye kunyangwe chinogona kusunga akawanda madiki ma hydrophobic mamorekuru, chiri chikuru chinangwa chingave kungoita sekunobva amino acids. Beta-lactoglobulin yakaratidzwawo kuve inokwanisa kusunga simbi kuburikidza nesiderophores uye nekudaro inogona kuve nebasa rekurwisa hutachiona.

Beta-Lactoglobulin inobatsira

Takatarisana nenyaya yekuti Whey protein musanganiswa we beta-lactoglobulin, alpha lactalbumin, bovine serum albumin, uye immunoglobins. Vanhu vanowanzo shandisa whey sekuwedzera, pamwe chete nekurwisa kurovedza muviri, kubatsira kuvandudza mhasuru protein synthesis uye kusimudzira kukura kweakaonda mhasuru.

Zvikwaniriso zviripo zvinosanganisira kubatsira kubatsira uremu, Anti-kenza midziyo, Kuderedza cholesterol, Asthma, Ropa kudzvinyirira uye chirwere chemoyo, Kuderedza uremu muvanhu vane hutachiona hweHIV.

Kusiyana neimwe yakakura Whey protein, α-lactalbumin, hapana basa rakajeka rakawanirwa β-lactoglobulin, izvi kunyangwe ichive chikamu chikuru chehukama hwemapuroteni epasi rose akaparadzaniswa ne Whey (β-lactoglobulin ≈⁠i65%, α-lactalbumin ≈≈⁠ ⁠25%, serum albin ≈≈⁠ ⁠ 8%, zvimwe ≈⁠i2%. β-lactoglobulin iprotein ye lipocalin, uye inogona kusunga akawanda emamolekyu e hydrophobic, zvichidudzira chikamu mukutakura kwavo. β-lactoglobulin yakaratidzwawo kuve inokwanisa kusunga simbi kuburikidza nesiderophores uye nekudaro inogona kuve nebasa rekurwisa hutachiona. Homologue ye β-lactoglobulin iri kushomeka mumukaka wechipfuva chemunhu.

Beta-Lactoglobulin (BLG) ndiyo yakawanda protein protein yakawanda mumukaka wembanje. LG yakadzidziswa zvakanyanya muindasitiri yezvikafu nekuda kwekudya kwayo uye zvinoenderana nekuita kwakasiyana siyana kwemaitiro.

Uyezve, BLG inogona kunge iri isingadhuri antioxidant zvinovaka muviri izvo zviri nyore uye nyore kuwana BLG inogona kuita senge antioxidant zvinovaka muviri iyo inowanikwa nyore uye yakachipa muhupenyu hwezuva nezuva. Chirevo chedu chekare chakaratidza kuti iyo yemahara cysteine ​​yeBGG inoita chinodzivirira mune antioxidant hunhu hwemukaka. BLG inoitisa 50% yemukaka antioxidant chiitiko. Kwete chete iyo BLG inoshanda yakanangana neye antioxidant zvinovaka muviri, inogona zvakare kutakura mamwe antioxidants kuburikidza neayo ligand inosunga homwe. Nekudaro, inowedzera zvese bioavailability uye huwandu hweanowanikwa antioxidants.

β-Lactoglobulin ndiyo yakakura Whey protein mu bovine mukaka inoverengera 50% yemapuroteni mu Whey asi isingawanikwe mumukaka wevanhu. β-Lactoglobulin inoburitsa zvakasiyana-siyana zvinoshanda uye zvinovaka muviri zvino zvaita kuti protein iyi ive inosimbisa zvinhu zvekushandisa mune zvakawanda zvekudya uye biochemical application.

 

Beta-Lactoglobulin mativi

Beta-lactoglobulin (b-lactoglobulin / BLG) ndomumwe wemaronda makuru mumukaka wemombe. Iyo ndeimwe yemapuroteni akajairwa mumukaka kukonzera mhedzisiro, asi vanhu vazhinji vanowanzokanganiswa nemaprotein mazhinji emukaka. BLG ndiyo yakawanda protein yakawanda mu Whey, inoverengera makumi mashanu muzana yeprotein yakazara mu lactoserum chidimbu uye inenge gumi muzana yemukaka wemombe.

Zviratidzo zvechirwere chinogadzirisa beta-lactoglobulin inogona kunge iri:

Tsvuku kana mikoko

Itching

Nausea

Bloating

Dumbu rakashata

Diarrhea

Kuzvimba

Constipation

Anaphylaxis (zvisingawanzo)
