I reckon the answer would be that phenol has a hydroxyl group (-OH) which is bonded to a phenyl ring. It yields the same positive result like tyrosine which has a hydroxyl group bonded to its phenyl ring.
tyrosine is not the answer the answer is actually impossible to find no scientist ever has been able to test xanthoproteic for protein
Rascals we already finding how can we answer it...damn
Yes
yes,
no
yes
Gelatin and egg albumin.
No because it doesn't contain aromatic group
The xanthoproteic test is a test for the detection of proteins. If proteins are present, concentrated nitric acid reacts with the proteins to form a yellow color that turns orange-yellow by the addition of alkali. This is called the xanthoproteic reaction.
no
Albumin and pepsin are both proteins, the test for proteins was positive.
Because it is a carbohydrates and molisch test will be positive in the presence of carbohydrates
yes
Phenylalanine gave a yellow to orange color in xanthoproteic test which means it is positive.
The xanthproteic test gives a positive result when proteins with amino acids carrying aromatic groups are present. Aromatic groups are functional groups consisting of a 6 hydrocarbons with alternating double and single bonds between carbon atoms forming rings.
yes
Gelatin and egg albumin.
No because it doesn't contain aromatic group
The xanthoproteic test is a test for the detection of proteins. If proteins are present, concentrated nitric acid reacts with the proteins to form a yellow color that turns orange-yellow by the addition of alkali. This is called the xanthoproteic reaction.
Heller's test is used to clinically detect the presence of albumin (protein) in urine.
Xanthoproteic test: a reaction due to the prescence of phenyl group (-C6H5) in the protein molecules. it involves the hnitration of the phenyl rings presnt in the aromatic amino acids such as tyrosine, phenylalanine, and tryptophan, forming yellow nitro-substitution products that turn orange when alkali is added (salt formation) Heller's ring test: this is usd clinically to detect the prescence of albumin in urine. so.... that's basically it... i hope i helped... ^^
