Alfa-lactalbumin (9013-90-5) Isi nyocha

Lactalbumin, nke a makwaara dị ka “protein whey”, bụ albumin dị n’ime mmiri ara ehi ma nweta site whey. A na-ahụ Lactalbumin n’ime mmiri ara ehi nke ọtụtụ ndị na-enye ara. Enwere alpha na beta lactalbumins; ha abụọ nwere mmiri ara ehi.

Ọmụmụ sayensị na-atụ aro na ụfọdụ ụdị lactalbumin (protein whey) nwere ike imeziwanye ihe ịgwọ ọrịa ma nwekwuo ọkwa nke glutathione n'usoro ụmụ anụmanụ ma nwee antiviral (megide nje), mgbochi apoptotic (na-egbochi ọnwụ mkpụrụ ndụ) na mgbochi tumo (megide ndị ọrịa cancer ma ọ bụ etuto ahụ). ) ihe omume na ụmụ mmadụ.

Gịnị bụ Alfa-Lactalbumin?

Alfa-lactalbumin bu protein eke whey nwere ihe ndi nwere ihe ndi ozo di nma na amino acid (BCAA) nke di nkpa. Ihe amino acids kacha ukwuu dị na alfa-lactalbumin bụ tryptophan na cysteine, yana BCAAs; leucine, isoleucine na valine.

N'ihi ọdịnaya dị elu nke amino asịd (BCAA, ~ 26%), karịsịa leucine, alpha-lactalbumin na-akwado ma na-akpali njikọta protein protein, na-eme ka ọ bụrụ ezigbo protein maka imeziwanye ahụ ike ma na-enyere aka igbochi sarcopenia n'oge ịka nká.

Alfa-lactalbumin bụ protein a na-ahụ na oke nke abụọ kachasị na protein whey kewapụrụ n’ihe dịka 17%. O nwere uru niile nke protein whey; ntụgharị, ọ bụ ihe zuru oke na-enye protein dị elu na EAA, nke nwere amino asịd nke amị acid (BCAAs), nwere oke nri, yana lactose-abụba na abụba.

Ọ bụ ihe mepụtara amino acid pụrụ iche na-eme alfa-lactalbumin nhọrọ protein zuru oke maka ndị mmadụ n'otu n'otu na-achọ ọtụtụ uru.

Alfa-lactalbumin bara ụba na amino acid nke di nkpa ma di kwa nma, obu kwa protein n’onwe ya na mmiri ara ehi. O dabara adaba na ngwa nri nri dị iche iche dịka ihe ọ Uụ Uụ UHT, mmanya na achịcha.

Alfa-lactalbumin bụ isi iyi bara ụba nke amino acid tryptophan na cysteine. N'ime abụọ ndị a, cysteine ​​na-apụta dị ka amino acid na-egbochi oke amamịghe nke glucose nke a mara amara iji belata nrụgide ume na ahụ mmadụ.

Kedu ihe kpatara Alfa-Lactalbumin?

Alfa-lactalbumin bu nke oma na tryptophan

Tryptophan bụ otu n'ime amino asịd dị na protein nri. Agbanyeghị, alfa-lactalbumin na-enye 48 mg nke tryptophan kwa gram nke protein, ọdịnaya ya kacha elu na isi mmalite nri nri niile.

Alfa-lactalbumin dị ka isi iyi protein na-abawanye ọkwa tryptophan ọbara, nke na-akwalite njikọ na nnweta serotonin na ụbụrụ. N'aka nke ya, serotonin kwadoro mmepụta nke melatonin, homonụ nke na-enyere aka ịhazi usoro ihi ụra.

Alfa-lactalbumin dị elu na cysteine

Alfa-lactalbumin na-enye 48 mg nke cysteine ​​kwa gram nke protein. Cysteine ​​bụ ihe pụtara kpọmkwem na antioxidant glutathione, nke so na usoro ahụ na-akwado sistemụ ahụ ji alụso ọrịa ọgụ, na-ewulite ma na-edozi anụ ahụ, na-echebekwa mmebi nke oxidative.

Alfa-lactalbumin bụ isi iyi nwere amino acid nwere sọlfọ nwere ezigbo mmiri

Alfa-lactalbumin whey protein nwere oke pụrụ iche 5: 1 nke cysteine ​​na methionine - ihe dị mma maka ahụ. Methionine dị n'etiti okirikiri nke methylation, usoro dị oke mkpa chọrọ folate, vitamin B12, na choline, ọ dịkwa mkpa maka njikọ nke nucleotides, ihe mgbochi ụlọ nke DNA.

Whey protein (gụnyere alfa-lactalbumin) bụ ezigbo mmiri amino asịd dị mkpa.

Whey protein dị elu na EAA, itoolu n'ime amino asịd iri abụọ nke ga-esiri na nri ahụ maka na anụ ahụ anaghị eme ka ya. Ọzọkwa, BCAAs, leucine kpọmkwem, na-ekere òkè kpọmkwem na ịmalite njikọta protein protein.

EAAs na-akwado iwughachi, ndozi, yana njikọ nke protein n’olu n’ịnyịnya protein dị ala ma ọ bụ belata obere caloric.

Alfa-lactalbumin whey protein nwere peptides bioactive

Mkpụrụ bio bioides nwere ihe onwunwe prebiotic ma nwee ngwa pụrụ iche maka ahụike mmadụ. Nnyocha na-egosi mmetụta ụfọdụ alfa-lactalbumin na gootu bụ akụkụ site na peptides bioactive site na njikọ pụrụ iche tryptophan na cysteine ​​yana mgbanwe mgbanwe ndị ọzọ nke amino acid ndị a.

Alfa-lactalbumin uru

Dika monomer, alpha-lactalbumin jikọtara calcium na zinc nke ọma ma nwee ike ịnwe ọgwụ nje ma ọ bụ ọgwụ antitumor. Mpempe pọịlị; nke alfa-lactalbumin, nke a na-akpọ HAMLET, nwere ike ịkpalite apoptosis na akpụ na sel akabeghị aka.

Alfa-lactalbumin dị na ọkwa 0.02% ka 0.03% na mmiri ara ehi, na-eme ka iche na ịdị ọcha bụrụ sayensị. Ọnụnọ ya n’ime mmiri ara nke mmadụ dị elu karịa, ugboro asatọ karịa; ya mere, iche na ncha nke alfa-lactalbumin na - enyere aka mmepe nke usoro umu aka nwa nke yiri mmiri ara nwa.

Alfa-lactalbumin dị ka isi iyi protein na-abawanye ọkwa tryptophan ọbara, nke na-akwalite njikọ na nnweta serotonin na ụbụrụ. N'aka nke ya, serotonin kwadoro mmepụta nke melatonin, homonụ nke na-enyere aka ịhazi usoro ihi ụra. Serotonin na-arụpụta ọtụtụ mmetụta ma na-emetụta ya na njikwa agụụ, ọnọdụ, usoro ihi ụra, ịrụ ọrụ cognitive na ikike ịnagide nchegbu.

Na onodu ohuru na protein nke International Society of Nutrition Sports, alfa-lactalbumin na-akwalite maka ikike ya iji mee ka ọnya na-agwọ ngwa ngwa, nke dị mkpa maka mgbake site na ọgụ na ịkpọtụrụ egwuregwu.

LALBA (Alpha-lactalbumin) nwere ọtụtụ ihe ndị dị ndụ, dịka ọmụmaatụ, njikọta kalịnda ion, ọrụ lactose synthase. Offọdụ ọrụ na-arụkọ ọrụ na protein ndị ọzọ, ụfọdụ n'ime ọrụ ndị LALBA nwere ike ịrụ ya.
