All amino acid having an aromatic ring give a positive xanthoproteic test under identical condition?
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.
What functional group gives a positive test in the xanthoproteic test?
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.
Why is the xanthoproteic test for phenol negative?
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.
Which halogens give a positive beilstein test?
Chlorine, bromine, and iodine give a positive Beilstein test. The test involves ignition of a compound in the presence of copper oxide, which forms a green flame due to the halogen present in the compound.
Do proteins give positive iodine tests?
Yes, proteins can give a positive iodine test. When iodine reacts with proteins, it forms a complex that results in a brown color change, indicating a positive test for proteins.
Why phenylalanine give negative result with xanthoproteic test?
Phenylalanine gave a yellow to orange color in xanthoproteic test which means it is positive.
Is albumin positive to xanthoproteic test?
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.
All amino acid having an aromatic ring give a positive xanthoproteic test under identical condition?
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.
Does human insulin give positive xanthoproteic test?
No because it doesn't contain aromatic group
What tripeptide will give a positive xanthoproteic test?
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.
Do albumin gives a positive xanthoproteic test?
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.
Why glysine give negative result in xanthoproteic test?
No because it doesn't contain aromatic group
Why are xanthoproteic and millon-nasse test unsatisfactory for the use in examination for proteins?
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.
What functional group gives a positive test in the xanthoproteic test?
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.
Why is the xanthoproteic test for phenol negative?
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.
Did gelatin give positive result with xanthoprotic test?
yes,it give positive test
What are the results when vasopressin is tested with xanthoproteic?
xanthoproteic test is used to detect the presence of aromatic amino acid in this nitration of an benzee ring with nitric acid takes place.
