Protheine ke eng

Liprotheine li fumanoa hohle 'meleng — mesifa, lesapo, letlalo, moriri le karolo e' ngoe le e 'ngoe ea' mele. E etsa li-enzyme tse matlafatsang liphetoho tse ngata tsa lik'hemik'hale le hemoglobin e tsamaisang oksijene maling a hau. Bonyane liprotheine tse fapaneng tsa 10,000 li u etsa seo u leng sona 'me li u boloke joalo.

Protein e fana ka matla ebile e tšehetsa tšebetso ea hau ea maikutlo le ea kelello. Ke phepo e hlokahalang bakeng sa ho aha, ho hlokomela le ho lokisa lisele, lisele le litho tsohle tsa 'mele.

Mananeo a Protein ke Eng?

Metsoako ea protheine ke mehloli ea protheine e tsoang lijong tsa liphoofolo kapa tsa limela, joalo ka lebese, mahe, raese kapa lierekisi. Metsoako ea liprotheine e tsoa mehloling e fapaneng mme e fumaneha ka mefuta e mengata. Batho ba li sebelisa ho eketsa boima ba mesifa, ho ntlafatsa sebopeho sa 'mele ka kakaretso le ho thusa ho fihlela litlhoko tsa protheine ea bona.

Empa Ke Mofuta Ofe oa Protein phofo o Nepahetseng?

Ho na le mefuta e mengata e fapaneng ea khetho ea phofo ea protheine ka ntle ho moo, e ka ikutloa e sithabetse ka linako tse ling. Mona ka tlase ke mohloli o 5 o motle oa phofo ea protheine.

1.Alpha-LactalbuminPhcoker

Alpha-lactalbumin ke protheine ea tlhaho ea Whey e nang le lintho tse phahameng ka tlhaho tse nang le li-amino acid tse ngata tsa bohlokoa (BCAA), e e etsa mohloli o ikhethang oa protheine. Li-amino acid tsa bohlokoahali ho alpha-lactalbumin ke tryptophan le cysteine, hammoho le li-BCAAs; leucine, isoleucine le valine.

Ka lebaka la dikahare tse phahameng tsa li-amino acid tsa mabokose (BCAA, ~ 26%), haholo leucine, alpha-lactalbumin e ts'ehetsa le ho tsosa phello ea protheine ea mesifa, e e etsa mohloli o motle oa protheine oa ho ntlafatsa bophelo bo botle ba mesifa le ho thusa ho thibela sarcopenia nakong ea botsofali.

2.Beta-LactoglobulinPhcoker

Beta-Lactoglobulin (ß-lactoglobulin, BLG) ke protheine e kholo ea lebese le lebisitsoeng hape e teng le lebeseng la liphoofolo tse ling, empa ha e fumanehe ka lebese la motho. Beta-lactoglobulin ke protheine ea lipocalin, 'me e ka tlama limolek'hule tse ngata tsa hydrophobic, e fanang ka maikutlo a karolo ho tsamaiso ea tsona. β-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. 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 lits'ebetso tsa biochemical.

3.Lactoperoxidase (LP)Phcoker

Lactoperoxidase ke enzyme ea tlhaho e fumanoang lebeseng la liphoofolo tse anyesang tse ngata, hammoho le maro a mang a 'mele a kang likhapha le mathe. E sebetsa e le sesosa, e matlafatsang ion ea thiocyanate moo ho nang le hydrogen peroxide ho hypothiocyanous acid. Asiti e ikarola ka lebese le ion ea hypothiocyanate e sebetsana le lihlopha tsa suphydryl ho inactivate enzymes ea metabolism. Sena se thibela libaktheria ho ngatafala mme ka mokhoa o fetisang boleng bo amohelehang ba lebese le tala.

Lactoperoxidase e tsejoa hore e na le thepa ea antimicrobial le antioxidant. Ho latela lipatlisiso tse phatlalalitsoeng ho Journal of Applied Microbiology, e na le thepa ea antibacterial e thusang letlalo mme e ka felisa libaktheria tse bakang makhopho. Lactoperoxidase le eona ke karolo ea bohlokoa motsoako oa metsoako o sebelisetsoang ho thibela li-yeasts, li-fungus, livaerase le libaktheria ho hola litlolo le lihlahisoa tse ling tsa botle.

Lactoperoxidase ke glycoprotein e nang le ts'ebetso e khahlanong le likokoana-hloko, e sebelisoa e le motsoako o tsitsitseng oa ho thusa ho ntlafatsa botsitso ba sebopeho le bophelo ba sehlahisoa-sehlahlo.

4.Immunoglobulin G (IgG)Phcoker

Immunoglobulin G (IgG) ke isotype ea antibody e ngata ka ho fetisisa maling (plasma), e etsang 70-75% ea li-immunoglobulins (antibodies). IgG detoxifying lintho tse kotsi 'me ke ea bohlokoa ho tsebisoang li-antigen-antibody complexes ka leukocytes le macrophages. IgG e fetisetsoa ka popelong ka placenta mme e sireletsa lesea ho fihlela sesole sa 'mele se sebetsa.

Immunoglobulin e ka tlama ho li-microorganisms tsa pathogenic le chefo ho theha li-antibodies, tse ka ntlafatsang ho itšireletsa ha tsamaiso ea batho ba baholo.

5.Lactoferrin(LF)Phcoker

Lactoferrin ke protheine e fumanehang ka tlhaho lebeseng ho tsoa ho batho le likhomo. E fumaneha le maro a mang a mangata 'meleng a joalo ka sesepa, likhapha, mushi le bile. Lactoferrin e fumanoa ka bongata ka ho fetisisa ka colostrum, mofuta oa pele oa lebese le hlahisoang ka mor'a hore ngoana a hlahe. Mesebetsi ea mantlha ea Lactoferrin 'meleng e kenyelletsa ho tlama le ho tsamaisa tšepe. E boetse e thusa ho loantša tšoaetso.

Lactoferrin e bohlokoa keketseho ea mesebetsi ea 'mele ea ho itšireletsa maseeng. E fana ka tšebetso e thibelang likokoana-hloko le ea ho itšireletsa mafung ho masea a batho. LF ke karolo ea tsamaiso ea 'mele ea ho itšireletsa mafung e ikarabellang bakeng sa ts'ireletso maemong a mucosal, ka lebaka la ts'ebetso ea eona e phahameng ea lithibela-mafu.

Lactoferrin le li-supplement tsa lactoferrin li ithutoe haholo. Batho ba bang ba nka li-suppact tsa lactoferrin ho fumana melemo ea antioxidant le anti-inflammatory.

Temong ea liindasteri, phofo ea lactoferrin e sebelisetsoa ho bolaea libaktheria nakong ea ts'ebetso ea nama.
