Cov tshuaj tiv thaiv xanthoproteic yog ib txoj hauv kev uas tuaj yeem siv los kuaj pom muaj cov protein soluble hauv cov tshuaj, siv cov concentrated nitric acid. Qhov kev sim ua rau qhov tshwm sim zoo hauv cov amino acids nqa cov tshuaj tsw qab, tshwj xeeb tshaj yog muaj tyrosine.
Yuav ua li cas yog lub luag haujlwm rau cov tshuaj tiv thaiv xim ntawm cov protein nrog Xanthoproteic test?
Xanthoproteic kuaj yog tshwj xeeb rau cov protein uas muaj cov amino acids uas muaj ntxhiab. Lub nplhaib benzene nyob rau hauv cov amino acids yog nitrated los ntawm cua sov nrog nitric acid thiab tsim daj nitro-compoundsuas tig mus rau txiv kab ntxwv xim nrog alkali.
Qhov txiaj ntsig zoo rau kev kuaj ninhydrin yog dab tsi?
Tus cim rau qhov kev kuaj ninhydrin zoo yog xim xiav sib sib zog nqus tau hauv cov tshuaj. Cov tshuaj tiv thaiv no qhia pom muaj cov amino acids, lwm yam amines thiab ammonia hauv cov qauv kuaj.
Cov tshuaj tiv thaiv xim ntawm cov protein yog dab tsi?
Proteins yog tsim los ntawm cov amino acid residue koom nrog peptide bonds. Vim muaj cov qauv peptide thiab muaj qhov sib txawv ntawm cov amino acid residues, proteins hnov mob nrog ntau hom reagents los ua cov khoom xim Cov kev ntsuam xyuas no paub tias yog xim cov tshuaj tiv thaiv protein.
Xim twg yog tsim los ntawm Millon qhov kev sim rau tyrosine?
Ib xim liab-xim av los yog precipitate qhia tias muaj tyrosine residue uas tshwm sim nyob rau hauv yuav luag tag nrho cov proteins. Qhov kev sim no yog tsim los ntawm Fab Kis tus kws chemist Auguste Nicolas Eugene Millon (1812–1867).

Kev kuaj ntshav puas tuaj yeem kuaj pom kev txhaj tshuaj?
Yog koj tsis paub meej tias koj puas tau txhaj tshuaj tiv thaiv tag nrho, koj tuaj yeem tshawb pom los ntawm Immunization Titer Test. Cov kev ntsuam xyuas no ntsuas cov tshuaj tiv thaiv hauv koj cov ntshav los txiav txim seb koj puas muaj kev tiv thaiv kab mob los yog yuav tsum tau txhaj tshuaj tiv thaiv .
Puas yog qhov kev xav rau qhov kev tshawb fawb no yog kev taw qhia lossis tsis ncaj ncees?
Cov Lus Qhia: Tsis yog, nws yuav tsum tsis yog kev taw qhiacov lus qhia taw qhia yog siv thaum kev tshawb fawb yav dhau los qhia tias qhov kev tshawb pom ntawm kev tshawb fawb yuav mus rau hauv ib qho kev taw qhia tshwj xeeb; Txawm li cas los xij, raws li cov ntawv sau tseg hais tias 'tus kws kho hlwb tsis paub txog kev tshawb fawb yav dhau los', qhov kev xav ntawm kev taw qhia yuav tsis tsim nyog .
Kev kuaj ntshav ib txwm tuaj yeem kuaj pom kev haus luam yeeb?
ntshav. Kev kuaj ntshav tuaj yeem kuaj pom nicotine nrog rau nws cov metabolites, suav nrog cotinine thiab anabasine. Nicotine nws tus kheej tuaj yeem muaj nyob hauv cov ntshav tsuas yog 48 teev, thaum cotinine tuaj yeem kuaj pom tau ntev txog peb lub lis piam .
