Which type of bond holds together amino acids in a protein?

A peptide bond is the specific type of bond that holds together amino acids in a protein. This bond forms through a dehydration synthesis reaction, where the carboxyl group of one amino acid reacts with the amino group of another amino acid, releasing a molecule of water and resulting in a covalent bond between the two amino acids. Peptide bonds are crucial for the primary structure of proteins, as they create long chains of amino acids that define the sequence and ultimately influence the protein's shape and function. Understanding this bonding mechanism is essential in biochemistry, as it lays the foundation for more complex protein structures formed by further interactions and bonding between different parts of the molecules.
