Notes Macromolecules Proteins Four levels of protein structure Primary structure is the linear sequence of amino acids determined by the genetic code. Secondary structure is the result of the hydrogen bonds b/t the backbone of the polypeptide. (beta pleated?) Tertiary structure is due to interactions b/t side chains (r- groups) including hydrogen bonds, hydrophobic interaction van der Walls, disulfide bridges, and ionic bonds. Bonds in tertiary structures are superbly imposed on the secondary structure. Quaternary structure is the result of two or more polypeptides aggregating
