What is one product of a condensation reaction between two amino acids, such as glycine and alanine?

Gly-Ala

(Dipeptide).

Explanation:

A condensation reaction is a reaction in which two molecules combine to form a single molecule with the loss of a small molecule e. g water.

When two amino acids, such as alanine and glycine react, they yield a mixture of dipeptides (via dipeptide bond) and water. That is, The - OH from the carboxyl group (-COOH) of one amino acid combines with a hydrogen atom from the amine group (-NH2) of the other amino acid to produce water.
