Preparation of valine by using Strecker synthesis needs to be shown. Concept introduction: Strecker synthesis is a process in which the aldehyde reacts with ammonium chloride and alkali cyanide to form α -aminonitrile. The formed α -aminonitrile is undergoes hydrolysis to give the respective amino acids. The general scheme can be shown as, Steps involved in Strecker synthesis are, Protonation of carbonyl Nucleophilic attack of ammonia to form imine Attack of cyanide to form α -aminonitrile Hydrolysis to give α -aminoacid

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.
