Cawv yog ua los ntawm fermenting ib tug natural qhov chaw ntawm qab zib nrog ib tug catalyst, uas feem ntau yog poov xab. Raws li nws ferments, cov carbohydrates (cov hmoov txhuv nplej siab thiab qab zib) nyob rau hauv lub ntsiab qhov chaw tig mus rau carbon dioxide thiab ethyl. cawv , uas yog lub hauv paus rau txhua tus cawv dej qab zib.
Tsis tas li ntawd, cov khoom xyaw tseem ceeb ntawm cawv yog dab tsi?
Cawv yog tsim los ntawm fermentation ntawm poov xab , suab thaj , thiab hmoov nplej . Cov txiv hmab txiv ntoo xws li txiv hmab txiv ntoo, thiab cov nplej xws li barley thiab hom qoob mog feem ntau yog siv rau cawv, npias, cawv thiab lwm yam khoom noj khoom haus-qib additives. Lwm yam nroj tsuag, xws li cactus lossis qab zib pas nrig tuaj yeem siv hauv kev tsim cawv.
Ib yam nkaus, peb txoj hauv kev uas ua cawv yog dab tsi? Cawv tuaj yeem ua tau los ntawm peb txoj kev sib txawv:
- Fermentation ntawm txiv hmab txiv ntoo los yog grain mix.
- Kev hloov kho tshuaj ntawm fossil fuels xws li roj, natural gas los yog thee (industrial alcohol)
- Kev sib xyaw tshuaj ntawm hydrogen nrog carbon monoxide (methanol lossis ntoo cawv)
Ib yam nkaus, tib neeg nug, cawv yog dab tsi?
Cawv (ethanol los yog ethyl cawv ) yog cov khoom muaj nyob hauv npias, cawv thiab cawv uas ua rau qaug cawv. Cawv yog tsim thaum cov poov xab ferments (so tsis muaj oxygen) cov suab thaj nyob rau hauv txawv zaub mov. Nrhiav kom paub txog lub zog (kilojoules / Calories) hauv cawv dej qab zib.
Cov cawv twg zoo rau kev noj qab haus huv?
Txawm li cas los xij, qee qhov cawv dej cawv yog zoo dua dua lwm tus. Red wine zoo nkaus li tshwj xeeb muaj txiaj ntsig vim nws siab heev noj qab nyob zoo antioxidants. Qhov tseeb, liab caw yog txuas nrog ntau dua noj qab haus huv cov txiaj ntsig ntau dua li lwm qhov cawv dej haus (74, 75, 76, 77, 78).
Pom zoo:
Dab tsi yog qhov sib txawv ntawm ethyl cawv thiab methyl cawv?
Qhov sib txawv ntawm methyl cawv thiab cawv cawv yog tias methyl cawv yog cawv cawv, uas yog tshuaj lom yog tias nws tau noj. Ethylalcohol yog cawv cawv. Txawm hais tias nws kuj yog qhov txaus ntshai hauv qhov ntau, nws yog cawv nyob hauv cov dej cawv. Txawm li cas los xij, ethanol muaj qhov txo qis zog ntau dua li roj av
Dab tsi yog creatinine thiab nws tsim tawm li cas?
Creatinine yog tsim los ntawm creatine, cov txheej txheem tseem ceeb rau kev tsim hluav taws xob hauv cov leeg. Creatinine tau thauj los ntawm cov hlab ntshav mus rau ob lub raum. Lub raum lim tawm feem ntau ntawm creatinine thiab pov tseg nws hauv cov zis. Txawm hais tias nws yog pov tseg, creatinine ua haujlwm tseem ceeb rau kev kuaj mob
Melanin yog dab tsi thiab nws txoj haujlwm yog dab tsi?
Melanin yog lub npe ntawm cov xim xim uas txiav txim siab xim dav ntawm daim tawv nqaij thiab plaub hau hauv tib neeg. Cov ntaub ntawv ntawm melanin yog lub luag haujlwm rau xim thoob plaws ntiaj teb tsiaj; Piv txwv li, tis xim hauv cov noog yog tsim los ntawm melanin
Plaque yog dab tsi thiab nws tsim li cas?
Cov quav hniav yog cov nplaum ua los ntawm cov khoom noj seem thiab cov qaub ncaug uas sib tov hauv koj lub qhov ncauj. Yog tias koj tsis txhuam zoo tom qab noj mov, nws pib tsim thiab txhim kho ntawm koj cov hniav. Qhov no muaj teeb meem vim cov quav hniav muaj cov kab mob, uas tuaj yeem ua rau cov hniav lwj thiab kab mob ntawm cov pos hniav
Hemoglobin yog dab tsi thiab yog vim li cas nws yog ib qho tseem ceeb protein?
Hemoglobin yog cov protein nyob hauv koj cov qe ntshav liab uas nqa oxygen mus rau koj lub cev thiab cov ntaub so ntswg thiab thauj carbon dioxide los ntawm koj lub cev thiab cov ntaub so ntswg rov qab mus rau koj lub ntsws. Yog tias qhov kev kuaj hemoglobin qhia tias koj qib hemoglobin qis dua li qub, nws txhais tau tias koj muaj cov qe ntshav liab tsawg (anemia)
