Answer The diagram for peptide bond formation between glycine and alanine is shown below. Explanation In the diagram, peptide bond is shown in red. The OH of carboxylic acid group of glycine and H of NH 2 group of alanine is removed as water for peptide bond formation. The peptide bond is basically an amide bond formed by the reaction of COOH and NH 2 group as shown in the diagram.

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.
