Tej zaum tsis muaj qhov zais cia tias aminocarboxylic acids (amino acids) yog cov hlaws dai hauv cov kab sib txuas ntawm cov proteins ntawm txhua yam kabmob muaj sia. Tab sis ob peb tug neeg paub tias yuav luag tag nrho lawv tau pom nyob rau hauv ib nrab ntawm lub xyoo pua xeem.

Cov biogenic sulfur-muaj cov amino acids txaus siab rau peb hauv kab lus no yog cysteine thiab methionine. Cia peb sim ua kom cov neeg nyeem paub ntau ntxiv txog cov organic tebchaw no los ntawm qhov pom ntawm biochemistry thiab biology ntawm peb kev noj qab haus huv.

Lub tsev thaiv cov protein

Amino acids (nrog rau cov sulfur-muaj cov khoom) yog cov organic tebchaw heev sawv cev hauv qhov xwm txheej. Niaj hnub no peb paub ntau tshaj 500 amino acids. Nyob rau tib lub sijhawm, 240 ntawm lawv tau pom nyob rau hauv ib puag ncig hauv daim ntawv dawb, thiab tag nrho cov seem yog cov khoom nruab nrab ntawm cov txheej txheem metabolic hauv cov kab mob nyob.

Thiab hnub no tseem nyobqhov tsis paub yog vim li cas ntawm tag nrho cov kev sib txawv no tsuas yog 20 amino acids pom nyob rau hauv tib neeg cov proteins (daim duab saum toj no). Lawv hu ua biogenic, los yog koom nrog cov protein biosynthesis. Ntawm cov "xaiv" tsuas yog ob qho yog sulfur-muaj amino acids. Cov no yog methionine (Methionine) thiab cysteine (Cysteine), uas muaj cov sulfur atom.

Txhua cov amino acids rau peb lub cev tau muab faib ua ob pawg: qhov tseem ceeb (cov uas tsis tau tsim hauv tib neeg lub cev) thiab tsis tseem ceeb (cov uas lub cev tsim tau nws tus kheej). Cysteine yog nyob rau pawg thib ob, tab sis methionine - rau thawj zaug, uas peb yuav tsum tau txais nrog cov zaub mov - nws yog nrog nws tias cov kab mob cuam tshuam, uas yog tshwm sim los ntawm kev ua txhaum ntawm cov metabolism ntawm sulfur-muaj amino acids. Tab sis ua ntej ua ntej.

C5H11NO2S yog dab tsi?

Methionine hauv nws daim ntawv ntshiab yog cov xim tsis muaj xim, tsis hnov tsw ntxhiab thiab soluble hauv dej. Qhov no yog ib qho amino acid uas ua hauj lwm raws li ib tug neeg muab khoom ntawm methyl pawg thiab sulfur nyob rau hauv peb lub cev. Raws li twb tau hais lawm, methionine yog ib qho tseem ceeb sulfur-muaj amino acid thiab tsis yog synthesized nyob rau hauv lub cev.

Nws yog los ntawm cov khoom noj thiab siv los ntawm peb cov hlwb los sib sau ua ke lawv cov proteins ntawm ribosomes. Qhov no sulfur-muaj amino acid muaj nyob rau hauv cov mis nyuj protein (casein), qe, noob hnav, hmoov, nqaij npuas thiab nqaij qaib, ntses (salmon thiab tuna), nplej thiab oats, legumes, tag nrho cov zaub ntsuab, parmesan cheese thiab mozzarella.

Ntxiv rau, cov tshuaj niaj hnub no muaj nyob rau hauv nws cov tshuaj arsenal uas zoo ib yam nkaus rau methionine. Ua tsaug rau nwsLub luag haujlwm hauv protein synthesis thiab fat soluble zog cov khoom no tau siv dav hauv kev ua kis las.

Tus nqi ntawm methionine rau lub cev

Lub biochemistry ntawm kev sib pauv ntawm sulfur-muaj amino acids muab peb lub cev nrog sulfur thiab methyl pawg. Cov amino acid no ua lub luag haujlwm tseem ceeb hauv kev sib txuas ntawm cysteine, taurine, adrenaline thiab melatonin.

Nws lub luag haujlwm hauv lub cev muaj ntau yam thiab dav:

  1. Koom nrog txo cov roj cholesterol thiab pab tiv thaiv atherosclerosis.
  2. Ua raws li hepatoprotector - tiv thaiv lub siab los ntawm kev tso cov roj ntau dhau, rov ua dua nws cov qauv.
  3. Zoo rau lub raum thiab excretory system.
  4. Ua raws li cov tshuaj tiv thaiv kev nyuaj siab, rov qab thiab ua kom pw tsaug zog zoo, tshem tawm kev qaug zog ntev.
  5. Txhim kho cov tawv nqaij, rau tes thiab plaub hau.
  6. Muaj peev xwm tiv thaiv cov hlau tsis huv, dawb radicals thiab yog li ua kom muaj kev lom zem ntawm lub cev.
  7. Txhim kho qhov mob ntawm cov pob qij txha. Nws tau raug pov thawj tias nyob rau hauv cov neeg mob uas muaj mob caj dab, tus naj npawb ntawm sulfur nyob rau hauv cov pob txha mos yog txo los ntawm 3 zaug piv rau cov qauv.

Thiab qhov no tsis yog daim ntawv teev npe tiav. Nws ntseeg tau tias txhawm rau muab peb lub cev nrog cov amino acid no, nws yuav tsum tau txais 19 mg ntawm methionine ib 1 kilogram ntawm qhov hnyav ib hnub.

C3H7NO2S - tiv thaiv thiab ntxuav

Cysteine yog ib qho amino acid uas yog synthesized hauv peb lub cev los ntawm methionine. Cov txheej txheem no yog ntau theem thiab tshwm sim nyob rau hauv lub xub ntiag ntawm tshwj xeeb enzymes, vitamins. Nws yuav ua tsis tautshwm sim ntawm txhua theem, thiab qhov no kuj tseem cuam tshuam nrog pathologies ntawm kev sib pauv ntawm sulfur-muaj acids.

Derivatives ntawm kev tawg ntawm cysteine yog taurine thiab glutathione. Thawj yog cov protein uas yog lub luag haujlwm rau kev ua haujlwm txaus ntawm lub hlwb, thiab qhov thib ob ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm lub cev tiv thaiv kab mob. Cysteine nws tus kheej cuam tshuam rau cov mob ntawm daim tawv nqaij (lub luag haujlwm rau collagen synthesis) thiab cov txheej txheem detoxification. Nws kuj yog ib feem ntawm ntau lub plab zom mov enzymes.

Vim lub cev

Nws yuav tsum tau sau tseg xws li kev ua haujlwm zoo ntawm cov amino acid no:

  1. Cysteine txhim kho plaub hau kev loj hlob los ntawm kev muab collagen synthesis, uas muaj txiaj ntsig zoo rau kev tsim ntawm daim tawv nqaij thiab tus qauv ntsia thawv.
  2. No sulfur-muaj amino acid pab tsim cov leeg thiab hlawv rog.
  3. Ua haujlwm ntawm cov tshuaj tiv thaiv antioxidant, tshem tawm cov co toxins, tshwj xeeb tshaj yog thaum noj cov vitamin C thiab selenium tib lub sijhawm.
  4. Ua kom cov leukocytes thiab lymphocytes, cuam tshuam rau lawv cov tshuaj tua kab mob, tshuaj tua kab mob, tshuaj tiv thaiv kab mob.

Txoj kev xav tau ntawm cysteine rau cov neeg laus noj qab haus huv txhua hnub yog txog li 3 grams tauj ib hnub. Nyob rau tib lub sijhawm, kev nce koob tuaj yeem ua rau muaj tshuaj lom lom.

Zoo nkauj zoo nkauj

Kev txiav txim siab qhov muaj methionine thiab cysteine yog ib qho yooj yim, thiab qhov kev paub no feem ntau tshwm sim hauv tsev kawm theem siab. Cov tshuaj tiv thaiv rau sulfur-muaj amino acids (Fol cov tshuaj tiv thaiv) yog ib qho ntawm ob peb nominal, zoo nkauj thiab zoo nkauj tshuaj hloov pauv.

ua tau li no. Nyob rau hauv ib lub raj tshuaj uas muaj lead acetate (1 ml), ntxiv 10% sodium hydroxide tov thiab nqaij qaib protein. Cessib tov yog rhuab. Cov nag dub tshwm nyob rau hauv lub raj kuaj, thiab qhov tsaus dua nws yog, qhov ntau cov sulfur-muaj amino acids muaj nyob rau hauv cov tshuaj.

Cov tshuaj tiv thaiv yog raws li kev sib cais ntawm leej faj nrog alkali los ua hydrogen sulfide, uas khi nrog sodium thiab precipitates.

Cov tshuaj tiv thaiv yog siv dav hauv kev tshawb fawb thiab tshuaj lom neeg, tshuaj.

Scarce conditions

Homocystinuria yog ib hom kab mob pathology ntawm cov metabolism ntawm sulfur-muaj cov amino acids. Nws cuam tshuam rau lub paj hlwb, musculoskeletal, vascular systems, nrog rau kev puas siab puas ntsws, convulsions, pathologies ntawm lub lens ntawm lub qhov muag thiab cov hlab ntsha ntawm lub paj hlwb, kev puas siab puas ntsws hauv kev tsim cov pob txha thiab cov leeg..

Qhov zaus ntawm pathology yog 1 kis rau 100 txhiab tus menyuam mos. Nyob rau hauv cov ntaub ntawv ntawm kev kuaj mob ntxov ntawm hom enzymopathy, kev kho mob suav nrog kev noj zaub mov tshwj tsis yog methionine thiab vitamin therapy.

Qhov no tsis yog tib txoj kev kho mob ntawm cov metabolism ntawm sulfur-muaj amino acids, tab sis lwm tus kuj tseem tsawg dua.

Tau txais kev puas tsuaj

Cov kev mob tsis txaus feem ntau tshwm sim lawv tus kheej nyob rau hauv daim ntawv ntawm cov rau tes nkig, plaub hau poob, o ntawm cov ntaub so ntswg, exacerbations ntawm cov kab mob ntawm lub plawv, daim siab thiab ob lub raum.

Cov neeg uas muaj acidity siab ntawm lub plab noj cov zaub mov uas nplua nuj nyob rau hauv methionine yog xyaum contraindicated. Nws ntau dhau hauv lub cev ua rau muaj kev ua xua, tsaug zog thiab digestive disorders.

Tab sis nyob rau hauv kev ntxhov siab thiab kev tawm dag zog lub cev, peb lub cev xav tau kev nce hauv sulfur-muaj amino acids hauvkev noj haus. Tsis tas li ntawd, cov poj niam cev xeeb tub yuav tsum tsis txhob tso tseg cov khoom noj uas nplua nuj nyob hauv lawv. Qhov no yog tus yuam sij rau kev tsim ntawm lub paj hlwb hauv fetus.

Slimming Helper

Nyob rau saum tsib amino acids uas yuav pab koj poob phaus, cysteine tsis yog qhov kawg.

methionine thiab cysteine
methionine thiab cysteine

Cov amino acid no qhia rau lub hlwb tias lub plab twb puv lawm. Ua tsaug rau cysteine, peb xav tias tag nrho. Thiab qhov no ua rau kev tiv thaiv overeating, poob phaus thiab nce tus nqi poob.

Noj zaub broccoli, oatmeal nrog txiv tsawb, qe, ntses hiav txwv - thiab qhov no anorexigenic amino acid yuav pab koj ua tiav daim duab.
