Nrog saj yog ib qho tseem ceeb ntawm peb tib neeg kev paub, nws yuav nyuaj rau ntseeg tias miv tsis muaj ntau yam saj li peb ua. Nyob rau hauv tsab xov xwm no, peb ua tib zoo saib raws nraim qhov kev tshawb fawb hais txog qhov tshwm sim tshwj xeeb thiab nws txhais li cas rau koj tus miv. Mus dhia dej!
Civ tsis tau saj Sweetness
Kev tshawb fawb luam tawm xyoo 20151 qhia tias miv tsis muaj cov receptors tshwj xeeb ntawm lawv tus nplaig kom saj qab zib. Nws tau ua los ntawm Monell Chemical Senses Center thiab pom tias ib qho ntawm ob lub noob tsim nyog rau cov khoom qab zib tau hloov mus rau qee qhov chaw, feem ntau yuav ntau lab xyoo dhau los. Qhov no tsis yog qhov xav tsis thoob, vim tias cov tswv tsev miv feem ntau paub tias lawv cov miv yuav xaiv ib lub tais ntawm nqaij qaib tshaj ib lub tais ntawm cov ice cream txhua hnub ntawm lub lim tiam. Uas tau hais tias, feem ntau cov neeg xav tias nws yog qhov teeb meem ntawm kev nyiam tshaj li qhov tsis muaj saj.
Vim ib tug miv cov zaub mov muaj cov nqaij ntau, nrog rau yuav luag tsis muaj kev xav tau carbohydrates, nws ua rau kev nkag siab tias lawv yuav tsis tau tsim cov receptors kom saj qab zib lossis tsawg kawg poob nws qhov chaw ntawm txoj kev.
Vim Li Cas Peb Thiaj Paub Tsi Taus Qab Zib?
Raws li cov kev tshawb fawb feem ntau, cov ntsiab lus yog qhov nyuaj, thiab qhov ua rau cov kws tshawb fawb txog lawv qhov kev txiav txim siab tuaj yeem nkag siab qhov yooj yim.
Hauv cov ntsiab lus tseem ceeb, cov tsiaj txhu feem ntau muaj cov khoom noj me me ntawm cov nplais ntawm lawv tus nplaig, uas tso cov khoom sib txuas nrog cov khoom noj thaum lawv nkag rau hauv lub qhov ncauj.

Lub qab zib receptor yog tsim los ntawm ob qho tib si proteins uas tsim los ntawm ob lub noob, hu ua Tas1r2 thiab Tas1r3. Hauv qhov xwm txheej, cov khoom noj qab zib yog me ntsis tsawg thiab yog ib qho kev qhia ntawm cov carbohydrates muaj txiaj ntsig, yog ib qho khoom noj tseem ceeb rau cov tsiaj cog qoob loo feem ntau. Txij li thaum miv tsis cia siab rau cov nroj tsuag rau kev noj qab haus huv, lawv tsis muaj cov amino acids uas tsim cov DNA ntawm Tas1r2, uas yuav ua rau nws tsis yooj yim rau saj qab zib. Interestingly, qhov no tshwm sim nyob rau hauv tag nrho cov miv, los ntawm koj tus hlub housecat mus rau tsov thiab tsov.
Cas Tseem Saj iab
Interestingly, txawm tias miv noj cov zaub mov feem ntau, lawv tseem tuaj yeem saj iab.

Txawm li cas los xij, lwm txoj kev xav qhia tias txij li thaum miv zom nyom (xav tias thaum lawv muaj teeb meem plab), lawv khaws cov receptors no.
Cov kws tshaj lij feem ntau ntseeg tias cov miv tau hloov zuj zus nrog cov iab iab no kom pom cov tshuaj lom hauv cov khoom noj, thiab muaj ntau cov tshuaj iab hauv qhov xwm txheej uas muaj tshuaj lom. Uas tau hais tias, kuj tseem muaj ntau cov iab tebchaw nyob rau hauv qhov uas noj qab haus huv, yog li qhov kev xav no yog questionable.
