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-).
1 A special kind of RNA called transfer RNA moves the amino acids to the ribosome. 2  It is abbreviated as tRNA where the t stands for transfer. 3  The bonds that link the amino acids in a protein together are called peptide bonds.he first step in making a protein is called transcription. This is when the cell makes a copy (or transcript) of the DNA. The copy of DNA is called RNA because it uses a different type of nucleic acid called ribonucleic acid.
