A peptide bond (amide bond) is a covalent chemical bond formed between two amino acid molecules.ne loses a hydrogen and oxygen from its carboxyl group (COOH) and the other loses a hydrogen from its amino group (NH 2). This reaction produces a molecule of water (H 2 O) and two amino acids joined by a peptide bond (-CO-NH-).
A protein is a peptide, but a peptide is not always a protein. As the article pointed out, a peptide with 50 or more amino acids is considered a protein. Anything less than that and it doesn't meet the protein qualification. covalent bond is a type of chemical bond that occurs when atoms share electrons. The specific type of covalent bond formed in these compounds is known as a peptide bond or amide bond, and it forms when the carboxl group of one amino acid attaches to another.
