Write down the reaction equation for the interaction of two aminoacetic acid molecules.

Amino acids are organic acids with two functional groups – carboxyl (-COOH) and amino (-NH2) groups. Therefore, they have both the general properties of all acids associated with the ability to dissociate with the formation of H (+), and the properties of carboxylic acids to form esters. But the presence of an amino group allowed them to connect with each other by forming a peptide bond: -CO-NH-
Reaction equation:
NH2 – CH2 – COOH + NH2 – CH2 – COOH = NH2 – CH2 – CO – NH – CH2 – COOH + H2O.
