Yes, albumin is positive to the xanthoproteic test. The xanthoproteic test is used to detect the presence of proteins containing aromatic amino acids, such as albumin, by forming a yellow color when treated with nitric acid.
No because it doesn't contain aromatic group
Phenylalanine. When phenylalanine is subjected to a xanthoproteic test, it will produce a yellow solution due to the reaction of the aromatic ring with nitric acid, indicating the presence of phenyl group in the tripeptide.
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.
The xanthoproteic test involves nitration of aromatic amino acids in proteins, which may not always be specific for proteins as other compounds containing these amino acids can give false positive results. The Millon-Nasse test is based on the reaction of phenol groups in proteins, which can also react with other substances containing phenol groups, leading to false positive results. Overall, these tests lack specificity and can give inaccurate results when used to examine proteins.
No, adrenaline will not give a positive xanthoproteic test. The xanthoproteic test is used to detect the presence of proteins, not hormones like adrenaline. Adrenaline is a hormone that is involved in the body's fight-or-flight response, and it does not react in the same way as proteins do in the xanthoproteic test.
Phenylalanine gave a yellow to orange color in xanthoproteic test which means it is positive.
Yes, albumin is positive to the xanthoproteic test. The xanthoproteic test is used to detect the presence of proteins containing aromatic amino acids, such as albumin, by forming a yellow color when treated with nitric acid.
No, not all amino acids with an aromatic ring give a positive xanthoproteic test. The xanthoproteic test is mainly positive for amino acids containing aromatic rings with phenolic groups such as tyrosine and phenylalanine. Aromatic amino acids like tryptophan do not give a positive xanthoproteic test under identical conditions.

The phenolic functional group gives a positive test in the xanthoproteic test. This test involves the reaction of phenolic compounds with concentrated nitric acid, resulting in a yellow coloration due to the formation of nitrophenols.
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.
