The structure of the dipeptide Gly-His at pH 5.5 and pH 7.5 should be drawn. Concept introduction: The ionization of an amino acid depends on the pH. In acidic pH, both amino group and carboxylate group are protonated. When pH increases, the carboxylic acid is the first to deprotonate. At higher pH’s the protonated form of amino group also lose a proton.

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.
