Does human insulin give positive xanthoproteic test?
No because it doesn't contain aromatic group
Do albumin gives a positive xanthoproteic test?
Yes, albumin can give a positive xanthoproteic test. The xanthoproteic test is used to detect proteins that contain aromatic amino acids like tyrosine, which can be found in proteins like albumin. When treated with concentrated nitric acid, these proteins turn yellow, indicating a positive test result.
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.
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 particles in an atom give its charge?
Protons, they have a positive charge.
Will adrenaline give a positive xanthoproteic test?
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.
Why phenylalanine give negative result with xanthoproteic test?
Phenylalanine gave a yellow to orange color in xanthoproteic test which means it is positive.
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
Do albumin gives a positive xanthoproteic test?
Yes, albumin can give a positive xanthoproteic test. The xanthoproteic test is used to detect proteins that contain aromatic amino acids like tyrosine, which can be found in proteins like albumin. When treated with concentrated nitric acid, these proteins turn yellow, indicating a positive test result.
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.
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.
What does adrenaline give you?
Adrenaline can give you a quick shot of energy, your heat starts to beat rapidly

Why glysine give negative result in xanthoproteic test?
No because it doesn't contain aromatic group
How do you use adrenaline in a sentence?
Adrenaline was still running through him after the race
What sports are known for causing adrenaline rushes?
Sports that give adrenaline rushes are commonly called extreme sports. Rock climbing, racing, fighting, rafting, and stunts featured on X games can cause adrenaline rushes for participants.
