What is the functional group of Glutamic acid?

The functional group of Glutamic acid is a carboxylic acid group (-COOH) and an amino group (-NH2), which are key components of amino acids.


What is the chemical attraction between the acid group of one amino acid and the amino group of another amino acid can form?

The chemical attraction between the acid group of one amino acid and the amino group of another amino acid is a peptide bond. This bond forms by a dehydration reaction where the carboxyl group of one amino acid reacts with the amino group of another amino acid, releasing a water molecule. Peptide bonds create the backbone structure of proteins by linking amino acids in a specific sequence.


Is there any amino acid having secondary amino group in its structure?

The amino acid proline is the only amino acid that has a secondary amine functional group. This is because proline is a cyclic amino acid that links the 3-carbon R-group back to the amine group, resulting in a secondary amine.


Is formic acid a simple amino acid?

No, formic acid is not a simple amino acid. It is a simple carboxylic acid with the chemical formula HCOOH. Amino acids are organic compounds containing an amino group (-NH2) and a carboxyl group (-COOH).


Why is glutamic acid an acidic amino acid and lysine a basic amino acid?

Glutamic acid is an acidic amino acid because it has a carboxylic acid group in its side chain, which can donate a proton, making it acidic. Lysine is a basic amino acid because it has an amino group in its side chain, which can accept a proton, making it basic.

Which amino acid has a ring?

Histidine is an amino acid that contains an imidazole ring in its side chain. The imidazole ring gives histidine unique chemical properties, making it important in enzyme catalysis and protein structure.
