A peptide is usually a short sequence of amino acids. Proteins are much larger structures, also comprised of amino acids, but having different levels of organisation such as forming secondary, tertiary and quaternary structures consisting of various poly peptide chains connected by hydrogen bonding in an alpha helix or a beta sheet (forming secondary structures).
