The structures of the two amino acids that are formed when asparagine and glutamine are decomposed in hot, concentrated HCl are to be written. Concept introduction: Proteins are large molecules that are constructed from the α- amino acids. The amino acids are joined by a group characteristic of amides in a stable protein. Since amides are least reactive acid derivative, it requires relatively extreme conditions to hydrolyze them. Thus to complete the hydrolysis of a protein, it requires strongly acidic conditions and very high temperature. The amino acid which has an amide group as a side chain is also hydrolyzed under these conditions. The relative amounts of each type of amino acid in a protein can be determined by the complete hydrolysis of the protein.

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.
