Methionine yog qhov tseem ceeb / qhov tseem ceeb / amino acids. Nws tseem tsis tau yog qhov kev paub zoo, tab sis ntawm lwm tes nws yog ib qho muaj zog heev antioxidant thiab tus yeeb ncuab ntawm ntau yam kab mob.

Nrog rau cysteine, methionine yog ib qho ntawm ob hom proteinogenic amino acids uas cov tshuaj lom neeg hauv cov qauv uas muaj cov tshuaj sulfur.

Methionine koom nrog hauv ntau ntawm cov enzymes thiab cov protein, nrog rau kev coj ua ntawm DNA thiab RNA, uas ua rau nws tseem ceeb heev rau kev rov ua haujlwm ntawm tes.

Cov txiaj ntsig ntawm methionine

Methionine txwv tsis pub cov rog ua kom lub ntsej muag thiab lwm lub siab ua kom lub siab puas tsuaj, yog li tiv thaiv lub hlwb, lub plawv thiab lub raum los ntawm cov ntshav cuam tshuam. Yog li ntawd, methionine xav tias muaj cov kev ua haujlwm tsis xws luag.

Raws li kev tshawb fawb tsis ntev los no, cov amino acid no txo txoj kev pheej hmoo ntawm mob qog nqaij hlav. Cov hluavtaws sib xyaw ntawm ob lwm cov amino acids, cysteine thiab taurine, kuj nyob ntawm lub xub ntiag methionine hauv lub cev.

Nws txhawb cov txheej txheem hauv cov zom zaub mov, muaj detoxifying ntxim rau cov khoom ua puas xws li cov hlau lead thiab cov hlau hnyav.

Glutathione yog qhov nruab nrab nruab nrab ntawm co toxins hauv lub siab, uas qhia tau tias methionine tswj hwm los tiv thaiv lub cev tseem ceeb no los ntawm kev puas tsuaj ntawm cov khoom lom.

Qhov chaw ntawm methionine

Methionine yog qhov tseem ceeb amino acid thiab yog li, nws tsis yog coj los ua ke hauv lub cev, tab sis tau los ntawm cov khoom noj muaj txiaj ntsig. Qib siab tshaj plaws ntawm methionine muaj nyob hauv ntses, khoom noj siv mis, nqaij, txiv ntoo, taum, lentils, qej.

Hauv feem ntau cov zaub thiab txiv hmab txiv ntoo, cov ntsiab lus ntawm methionine tsawg heev. Cov ntawm lawv uas muaj ntau dua cov tshuaj methionine yog taum pauv, taum thiab pob kws.

Vim tias lub cev siv cov methionine los tsim choline (khoom noj rau lub hlwb), nws yog qhov zoo uas yuav tsum tau choline lossis lecithin kom tsis txhob txo cov khoom ntawm methionine.

Methionine kom tsawg

Methionine tsis muaj peev xwm

Cov txiaj ntsig ntawm ntau cov kev tshawb fawb qhia tau tias tsis muaj methionine hauv lub cev ua rau cov kev txuam nrog cov roj (cholesterol), cov plaub hau thiab atherosclerosis.

Raug mob los ntawm methionine

Methionine yuav tsum zam los ntawm cov poj niam cev xeeb tub lossis pub niam mis tshwj tsis yog los ntawm kws kho mob. Kev hloov tsis zoo ntawm methionine, ntawm qhov tod tes, tuaj yeem txaus ntshai thiab txawm ua rau mob atherosclerosis.

Kev saib xyuas yuav tsum tau noj nrog koob tshuaj txhua hnub methioninevim tias thaum nws ntau dhau, lub cev hloov ua ib feem ntawm nws mus rau homocysteine, uas yog qhov phom sij tshwj xeeb rau cov tib neeg kev mob plawv.
