Kev txiav dos yuav ua li cas nrog kua muag?

Tsis muaj qhov tsis ntseeg tias cov dos yog ib qho ntawm cov khoom noj zoo tshaj plaws uas ntxiv qhov qab thiab qab saj rau cov pluas noj, txawm tias lawv yog grilled, kib, siav los yog nyoos, ntxiv rau muaj ntau yam khoom noj khoom haus zoo rau lub cev.

Txawm li cas los xij, nws muaj "kev cuam tshuam" tus cwj pwm, raws li nws qhia nws txoj kev tiv thaiv nkaus xwb rau cov neeg uas tsoo nws, thiab "ua pauj" txhua tus los ntawm kev ua rau lawv quaj ua ntej ntsib nws qhov kawg. Dab tsi yog qhov zais cia tom qab ntawd?

Cov kws tshawb fawb hu cov dos qhov tsim kua muag, uas yog cov tshuaj uas ua rau lub qhov muag mob hnyav heev.

Cov dos hauv lawv lub xeev (tsis raug txiav) muaj ob qhov sib xyaw ua ke, "cysteine ​​​​sulfoxides" thiab ib qho enzyme hu ua "alinase".

Tab sis thaum nws hlais, tsuav, los yog crushed, lub barrier cais ob lub tebchaw, thiab ob los ua ke, tsim ib qho kev tshwm sim. Lub enzyme allinase hloov cysteine ​​​​sulfoxides rau hauv sulfonic acid, sulfur compound.

Sulfuric acids muaj ob txoj kev xaiv

Josie Silveraroli, Pharm.D. los ntawm Ohio State University thiab thawj tus kws sau ntawv ntawm 2017 txoj kev tshawb fawb luam tawm nyob rau hauv phau ntawv Journal of the American Chemical Society “CS Chemical Biology,” ntawm lacrimal factor hauv dos, hais tias, “Sulfuric acids muaj ob txoj kev xaiv: Thawj qhov kev xaiv yog tias lawv tuaj yeem ua rau nws tus kheej condenses thiab reacts nyob rau hauv nws tus kheej, dhau los ua organosulfur compound. "

Silveraroli tau piav qhia rau cov ntawv xov xwm tshawb fawb "Live Science" tias "cov tshuaj sulfur organic yog dab tsi muab cov dos nws cov ntxhiab tsw thiab tsw," sau tseg tias "cov tshuaj tiv thaiv zoo sib xws tshwm sim hauv qej, thiab vim li no nws muaj pungent tsw."

Thiab nws hais ntxiv, "Tab sis qhov kev xaiv thib ob ntawm sulfonic acid yog qhov tshwj xeeb rau cov dos thiab lwm khub ntawm Allium (ib genus ntawm cov nroj tsuag), los yog genus ntawm paj ntoo uas tsim zaub xws li dos, qej, ntsuab dos thiab leeks," ceeb toom. hais tias "muaj lwm enzyme hu ua kua muag factor synthase, Nws nkaum hauv lub cell thiab plays lub luag hauj lwm, rearranging sulfonic acid nyob rau hauv lub lacrimal yam."

volatile kua

Nws kuj tau hais ntxiv tias "tus neeg ua kua muag yog cov kua muag tsis haum, uas txhais tau tias nws hloov mus ua vapor sai heev. Yog li ntawd, nws ncav cuag koj ob lub qhov muag thiab irritates lub paj hlwb, thiab lub qhov muag pib secrete kua muag kom tshem tawm irritants. "

Nws tau hais tias "nws muaj peev xwm hais tias ob qho tib si organosulfur tebchaw uas muab cov dos lawv cov tsw qab thiab lub kua muag tau hloov zuj zus los ua cov txheej txheem tiv thaiv hauv cov nroj tsuag no," sau tseg tias "lawv lub hom phiaj yog kom tsis txhob muaj kab, tsiaj txhu los yog kab mob uas yuav ua rau cov dos. cog."

Cov kev daws teeb meem yog dab tsi?

Raws li "Live Science" magazine, nws raug nquahu kom hnav tsom iav tiv thaiv lossis lo ntsiab muag thaum txiav cov dos, lossis txhua yam uas tuaj yeem ua rau muaj kev cuam tshuam ntawm dos thiab lub ntsej muag.

Nws kuj tau taw qhia tias rab riam ntse ua rau muaj kev puas tsuaj ntawm cov hlwb me me, uas ua rau txo qis ntawm qhov sib xyaw no thiab txo qhov teeb meem.
