The pH value at which a solution of the given amino acid would have no net charge should be indicated. 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. The isoelectric point is the pH at which, a molecule does not have any net charge. And pI can be calculated using following formula pI = pK a 1 + pK a 2 2 . pI − isoelectric point. K a1 and K a2 − dissociation constant of alpha amino group and alpha carboxylic 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.

Biochemistry Please help. Thank you What is the importance of glutamic acid in the metabolism of nitrogen from amino acids? (we know therole; it’s used to remove the nitrogen from amino acids so that the remaining carbon skeleton can bebroken down by the “usual” pathways, but what is the important, unique role that only glutamicacid/glutamate can do?)
