What else can I help you with?
Does adrenaline give a positive result to xanthoproteic test?
Yes, adrenaline gives a positive result in the xanthoproteic test. This test is used to detect the presence of aromatic amino acids, such as tyrosine and tryptophan, by reacting them with concentrated nitric acid, which produces a yellow coloration. Since adrenaline contains a phenolic structure derived from tyrosine, it reacts positively in this test, indicating the presence of these aromatic compounds.
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.
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.
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.
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.
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.
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.
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
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.
If your spouse needs encouragement Would you give them Negative Entergy or Positive?
positive
What is a negative divided by a positive divided by a negative?
The best way to figure this out would be to use an example. So suppose you had a -20 and divided that by a positive 5. That would give you a -4. Take that -4 and divide it by a -2 which would give you a positive 2 (knowing that two negative numbers cancel out to make a positive number). Thus a negative divided by a positive divided by a negative would give you a positive number.
