Question

CH2-NH2-COOH+CH2-NH2-COOH​

Answer 1

NH2-CH2-COOH + NH2-CH2-COOH=NH2-CH2-CO-NH-CH2-COOH+H2O

Answer 2

The expression CH2-NH2-COOH + CH2-NH2-COOH represents two molecules of aminoacetic acid (also known as glycine) reacting with each other. Glycine is the simplest amino acid with the chemical formula C2H5NO2.

When two molecules of glycine react, the amino (NH2) group from one molecule reacts with the carboxyl (COOH) group from the other molecule, resulting in the formation of a peptide bond. The reaction can be represented as:

CH2-NH2-COOH + CH2-NH2-COOH → CH2-NH-CO-NH-CH2-COOH + H2O

The product formed is a dipeptide, which consists of two amino acids linked together by a peptide bond. In this case, the dipeptide formed is glycylglycine.

Please note that the representation of the reaction assumes that the amino acids react under appropriate conditions and in the presence of a catalyst, such as an enzyme or a chemical reagent, that facilitates the formation of the peptide bond.
