The heptapeptide sequence of amino acids, on the basis of the information provided, is to be deduced. Concept introduction: On treating a polypeptide with 2,4-dinitrofluorobenzene in basic solution, the free amino group of the N-terminal gives a nucleophilic aromatic substitution reaction, which, on hydrolysis, gives a mixture of amino acids in which the N-terminal amino acid is labeled with a 2,4-dinitrophenyl group. The C-terminal residues are identified through the carboxypeptidase enzymes. These enzymes catalyze the hydrolysis of the amide bond of the amino acid residue containing a free liberating carboxylic acid group.

Answer 1

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.
