Xanthoproteic acid yog cov xim daj nrog cov mis C 34H24N 4 O122HO.
Cov kua qaub twg hu ua Xanthoproteic acid?
Nitric acid reacts nrog cov proteins los tsim cov khoom daj nitrated. Cov tshuaj tiv thaiv no hu ua xanthoproteic cov tshuaj tiv thaiv.
Dab tsi yog cov tshuaj siv hauv Xanthoproteic kuaj?
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 concentrated nitric acid. Qhov kev ntsuam xyuas muab cov txiaj ntsig zoo hauv cov amino acids nqa cov pab pawg muaj ntxhiab, tshwj xeeb tshaj yog muaj tyrosine.
Dab tsi amino acid muaj nyob hauv Xanthoproteic test?
Xanthoproteic kuaj yog siv los kuaj xyuas cov amino acids uas muaj cov tshuaj tsw qab ( tyrosine, tryptophan thiab phenylalanine) hauv cov tshuaj protein uas muab cov xim daj nitro derivatives ntawm cua sov nrog conc. HNO 3. Lub nplhaib uas muaj ntxhiab benzene undergoes nitration muab cov khoom xim daj.
Vim li cas NaOH ntxiv hauv 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 ua daj nitro-compounds uas tig mus rau txiv kab ntxwv xim nrog alkali. … Txias lub raj mis thiab ntxiv 2mL ntawm 20% NaOH (los yog tshuaj ammonia) kom nws alkaline
