What else can I help you with?
What funtional group will give a positive results with ninhydrin reagents?
Amino groups (NH2) will give a positive result with ninhydrin reagent, forming a purple-colored complex when reacted. This reaction is commonly used to detect the presence of amino acids, peptides, and proteins.
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 group do amino acids always contain?
The amino acids are distinguished by the R groups which determines what amino acid it is.
Which pair of functional groups are involved in the reaction of amino acids to give peptides?
The functional groups involved in the reaction of amino acids to give peptides are the amine group (-NH2) and the carboxyl group (-COOH).
Will methionine give lead acetate test?
Lead acetate test is used to detect the presence of sulfur-containing amino acids like cysteine and homocysteine, not methionine. Methionine does not give a positive result in the lead acetate test.
What funtional group will give a positive results with ninhydrin reagents?
Amino groups (NH2) will give a positive result with ninhydrin reagent, forming a purple-colored complex when reacted. This reaction is commonly used to detect the presence of amino acids, peptides, and proteins.
Will superpump 250 give a positive drug test?
NO its just caffein and amino acids.
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.
Will glutamic acid give a positive biuret test?
Amino acids doesn't react with the biuret reagent.
What color develops when ninhydrin react with amino acids?
These are the amino acids that will yield positive result to the ninhydrin test: Non-polar amino acids: Glycine, Alanine, Valine, Leucine, Isoleucine, Phenylalanine, Methionine, Tryptophan Polar Neutral Amino acids: Serine, Cysteine, Threonine, Asparagine, Glutamine, Tyrosine Polar Acidic Amino Acids: Aspartic acid and Glutamic acid Polar Basic Amino Acids: Histidine, Lysine, Arginine
Will Alanine give a negative Biuret test?
Yes, alanine will give a negative Biuret test. The Biuret test is used to detect the presence of proteins, which are made up of long chains of amino acids. Since alanine is a single amino acid, it will not give a positive response in the Biuret test.
Will amino energy give me a positive reading on drug test?
No. Amino acids are the building blocks of protein; if they'd make you fail a drug test everyone would fail every drug test they take because not only do you eat protein, your body makes many amino acids on its own.
Amino acids contain two common functional groups an amino group and an?
Amino acids contain two common functional groups - an amino group (-NH2) and a carboxyl group (-COOH). These groups give amino acids their distinctive properties and are involved in forming peptide bonds between amino acids to create proteins.
What group do amino acids always contain?
The amino acids are distinguished by the R groups which determines what amino acid it is.
Which pair of functional groups are involved in the reaction of amino acids to give peptides?
The functional groups involved in the reaction of amino acids to give peptides are the amine group (-NH2) and the carboxyl group (-COOH).
How many amino acids were changed?
To determine how many amino acids were changed, you would need to compare the amino acid sequences of the original and mutated proteins. By aligning the two sequences, you can count the positions where the amino acids differ. This count will give you the total number of changed amino acids. If you provide specific sequences or context, I can help you analyze them further.
What are the names of the two chemical groups that all amino acids have in common?
Amino = Amine Acid = Carboxylic Acid These two groups are what give amino acid's there name. Source: http://en.wikipedia.org/wiki/Amino_acid
