Daim ntawv thov
Isobutyric acid feem ntau yog siv los ua cov khoom lag luam isobutyrate, xws li methyl isobutyrate, propyl isobutyrate, isoamyl isobutyrate, thiab lwm yam. Nws siv los ua zaub mov tsw thiab siv hauv khw muag tshuaj.
Cia
1). Kev Tiv Thaiv Kev Tiv Thaiv Cia Cia hauv qhov chaw txias, qhov cua txias. Lub tsev khaws khoom kub yuav tsum tsis pub tshaj 37 degree.
2). Khaws kom deb ntawm qhov hluav taws kub thiab qhov chaw kub. Khaws lub thawv kaw.
3). Nws yuav tsum tau muab cais los ntawm cov neeg ua haujlwm oxidizing, txo cov neeg ua haujlwm thiab alkalis, thiab yuav tsum tsis txhob sib xyaw.
4). Siv cov khoom tawg-pov thawj hom teeb pom kev zoo thiab qhov cua qhov chaw.
5). Txwv tsis pub siv cov khoom siv hluav taws xob thiab cov cuab yeej siv hluav taws xob.
6). Qhov chaw cia khoom yuav tsum tau nruab nrog cov khoom siv thaum muaj xwm txheej spillage thiab cov ntaub ntawv tsim nyog.
Cov tshuaj tiv thaiv
Cov kua qaub reacts raws li ib tug raug carboxylic acid: nws muaj peev xwm tsim amide, ester, anhydride, thiab chloride derivatives.Nws cov kua qaub chloride feem ntau yog siv los ua tus nruab nrab kom tau txais lwm tus.Thaum rhuab nrog ib tug chromic acid tov nws yog oxidized rau acetone.Alkaline poov tshuaj permanganate oxidizes rau -hydroxyisobutyric acid, (CH3)2C(OH)-CO2H.
Siv
Isobutyric acid thiab nws cov volatile esters yog tam sim no nyob rau hauv ib tug ntau yam ntawm cov khoom noj thiab, ntawm txawv ntau yam, muaj peev xwm muab tau ib tug ntau yam ntawm flavors.Lub compound muaj kev ruaj ntseg raws li ib tug khoom noj additive yog tshuaj xyuas los ntawm FAO thiab WHO vaj huam sib luag, uas txiav txim siab tias tsis muaj. kev txhawj xeeb ntawm cov qib yuav tau txais.
Biology
Hauv tib neeg, isobutyric acid yog ib qho khoom me me ntawm lub plab microbiome thiab tuaj yeem tsim los ntawm cov metabolism hauv nws cov esters pom hauv cov zaub mov. uas yog tig los ntawm butyric uas yog tig los ntawm lo lus Latin rau butter thiab Greek, ούτυρον) tab sis anosmia rau nws tau tshaj tawm txog 2.5% ntawm cov neeg.
Cov metabolism hauv isobutyric acid hauv cov nroj tsuag tau kawm.
Isobutyric acid, nrog rau ob peb lwm yam luv luv-chain fatty acids ua ke hu ua "copulins," muaj ntau nyob rau hauv tib neeg qhov chaw mos secretions. Qib ntawm isobutyric acid fluctuate thoob plaws hauv kev coj khaub ncaws, thiab nws yog hypothesized los ua ib qho kev qhia ntawm ovulatory xwm txheej.Zoo sib xws yog pom nyob rau hauv chimpanzees.
