A peptide bond, which at times called an amino bond) is a covalent chemical bond that is formed between two amino acids in order to form polypeptide strands that form proteins (such as enzymes). A peptide bond forms between the carboxyl group (-COOH) of one molecule and the amino group (-NH) of a second molecule. The resulting CO-NH bond called a peptide bond.  In the process, a water molecule is removed. For this reason, the formation of a peptide bond is categorized as a dehydration synthesis, or condensation, reaction. 

Peptide bonds are formed during protein synthesis that requires the use of ribosomes and mRNA, tRNA, and rRNA. This process is nicely simplified and displayed utilizing the hyperlink or URL found below. 

Good luck!
