Unformatted text preview: secondary and tertiary protein structure. As peptide bonds are formed, aligning the amino acids, hydrogen bonds form between different amino acids in the chain. This bonding coils the polypeptide into the secondary structure of the protein, most commonly the alpha helix, discovered by Linus Pauling. The ±-helix coils at every 4 th amino acid. ± Helix Pleated Protein Some regions of the polypeptide have portions that lie parallel to each other (still held by hydrogen bonds) instead of in the alpha helix, in which the amino acids' hydrogen bonds form a pleated structure. Fibrous proteins have significant pleated structures....
