Answer
Peptide bond, a bond covalently linked, forms between two amino acids via a dehydration synthesis or condensation reaction, resulting in the loss of a water molecule. A peptide link CO-NH-, links two amino acid molecules in a dipeptide. Described in chemical reaction:**

Explanation
## Step 1: A peptide bond forms between two amino acids during a process known as dehydration synthesis, or a condensation reaction. ## Step 2: In this process, the carboxyl group (-COOH) of one amino acid and the amino group (-NH2) of the other amino acid come close together. ## Step 3:The hydrogen atom from the amino group of one amino acid combines with the hydroxyl group (OH) from the carboxyl group of a second amino acid, creating a molecule of water (H2O). Thus, the term "dehydration synthesis."## Step 4:The residue after the response is a peptide bond (-CO-NH-), joining the two amino acids together. ## Step 5:As specifically, when two amino acids link to form a dipeptide, this reaction results in the creation of one water molecule and a dipeptide essentially a molecule of two connected amino acids.### Formula of Peptide Bond Formation:**
**Where **R** and **R'** represent the side chains of the individual amino acids, which can vary.
