What else can I help you with?
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
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.
What samples did not give a positive test with xanthoproteic test why?
The xanthoproteic test is used to detect the presence of aromatic amino acids, particularly tyrosine and tryptophan, by turning yellow upon reaction with nitric acid. Samples that do not contain these amino acids, such as certain non-aromatic amino acids (e.g., glycine, alanine) or peptides and proteins lacking these residues, will not yield a positive test. Additionally, any substances that do not contain proteins or peptides, such as carbohydrates or lipids, will also not give a positive result. Thus, the absence of aromatic amino acids or proteins in the sample is the reason for a negative xanthoproteic test.
Is egg albumin positive to millon test?
Yes, egg albumin is positive for the Millon's test due to the presence of aromatic amino acids like tyrosine, which react with Millon's reagent to produce a red color.
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.
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.
Will albumin give positive result to Benedict test?
No, albumin will not give a positive result to the Benedict test. The Benedict test is used to detect the presence of reducing sugars such as glucose, fructose, and maltose, not proteins like albumin.
Why does albumin and pepsin test positive for protein?
Albumin and pepsin test positive for protein because they are proteins themselves. Proteins can be detected using various biochemical tests that target specific protein characteristics, such as their amino acid sequences or ability to react with certain reagents.
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.
Why albumin gives positive Molisch test?
Because it is a carbohydrates and molisch test will be positive in the presence of carbohydrates
Does human insulin give positive xanthoproteic test?
No because it doesn't contain aromatic group
Does adrenaline give a positive result to xanthoproteic test?

Thus, the absence of aromatic amino acids or proteins in the sample is the reason for a negative xanthoproteic test.
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.
Is egg albumin positive to millon test?
Yes, egg albumin is positive for the Millon's test due to the presence of aromatic amino acids like tyrosine, which react with Millon's reagent to produce a red color.
