3,4'-dicarboxy-4-hydroxy azo benzene.

it is a coupling reaction...........it forms a azo dye.

when salicylic acid reacts with amino benzoinc acid.. initially amino benzoinc acid

reacts with nitrous acid and hydrochloric acid to form azo group....

azo group: -N=N-

then that azo compound react with salicylic acid to form an azo dye

(3,4'-dicarboxy-4-hydroxy azo benzene).

C6H4COOH(OH)-salicylic acid

C

H2NC6H4CO2H- amino benzoinc acid.

H2NC6H4CO2H+HNO2+HCL-->CL-N=N-C6H4COOH

(AZO COMPOUND)

3,4'-dicarboxy-4-hydroxy azo benzene.

(AZO DYE)

The azo dye formed when salicylic acid reacts with amino benzoic acid is salicylazobenzoic acid. This reaction involves the formation of an azo bond between the two components, resulting in the production of a colored compound.

How are amino acids held together?

Amino acids are held together by peptide bonds, which are formed when the carboxyl group of one amino acid reacts with the amino group of another amino acid, releasing a water molecule in a condensation reaction. This bond forms a peptide chain in proteins.


What is the linkage or bond that is formed between two amino acids to form a protein?

A peptide bond is formed between two amino acids to link them together and form a protein. This bond is created through a dehydration synthesis reaction, where the carboxyl group of one amino acid reacts with the amino group of another amino acid, releasing a water molecule in the process.


What type of molecule is formed of amino acids?

What type of bond forms between the new amino acid and the previous amino acid on the chain?

A peptide bond forms between the new amino acid and the previous amino acid on the chain during protein synthesis. This bond is formed through a dehydration reaction, where the carboxyl group of one amino acid reacts with the amino group of the other amino acid, releasing a molecule of water in the process.


Proteins are formed from?

Amino acids.


What links form the protein chain in protein synthesis?

Peptide bonds are formed between amino acids during protein synthesis. These bonds are created through a condensation reaction, where the carboxyl group of one amino acid reacts with the amino group of another amino acid, releasing a water molecule in the process.


What happens when you bond two amino acids together?

When two amino acids bond together, a peptide bond is formed. This bond is created through a condensation reaction, where the carboxyl group of one amino acid reacts with the amino group of another amino acid, resulting in the release of a water molecule. Peptide bonds are the building blocks of proteins and help to link amino acids into long chains.


What is formed when an amino group is substituted for a hydrogen?

When an amino group is substituted for a hydrogen, ammonia is formed. You can form more compounds by substituting the various elements in an amino group.


What types of bonds are the ones that attach amino acids to each other in a growing polypeptide?

They are amide bonds -covalent. When an amino acid reacts with another, the carboxylic acid reacts with the amine forming an amide.


What forms a peptide bonds?

Peptide bonds are formed through a condensation reaction between the carboxyl group of one amino acid and the amino group of another amino acid. This reaction involves the loss of a water molecule and results in the formation of a covalent bond between the two amino acids.


Are proteins formed from carbohydrates?

No, proteins are formed from amino acids.


The nutrient formed by amino acids?

Proteins are nutrients formed by amino acids. Amino acids are the building blocks of proteins and are essential for the growth, repair, and maintenance of body tissues.
