Protein Structure. Proteins are polymers of amino acids. The amino acids of a protein are linked by peptide bonds. Alpha helices and beta pleated sheets are characteristic of a protein's secondary structure. Electronegative oxygen and nitrogen atoms leave hydrogen atoms with partial positive charges. Peptide bonds link together the amino acids of a protein's primary structure.
Posted on. (Answer #1). The most common types of secondary protein structures are alpha helices and beta sheets. Alpha helices are right handed coils of amino acids that form helical structures, similar to a coiled tube.The hydrogen bonding pattern of an alpha helix keeps all of the hydrogen bonds within the interior of the coil.Answer #1).
