Which parts of the amino acids x and y are involved in the formation of a peptide bond?

The carboxyl group of x and amino group of Y

Explanation:

An amino acid is made up of a carboxyl (-COOH) functional group, an amino (-NH2) functional group and a side chain (R group) . In the joining of two amino acid molecules, a chemical bond called the peptide bond is formed. The peptide bond is formed by the chemical a reaction between the acid carboxyl group (-COOH) of amino acid X and the amino group (-NH2) of amino acid Y. This reaction is referred to a condensation reaction as one molecule of water is lost in the reaction.

The continuous linkage and formation of peptide bonds between amino acids result to the formation of a polypeptide chain.

An organic molecule that composes functional group amino and carboxylic acid with a side chain distinct for the acid is called amino acids.

The carboxyl group (x) and an amino group (y) are required in peptide formation.
