WitrynaHydrogen bonding plays a vital role in physiological systems. Proteins contain chains of amino acids. The amino acid units are arranged in a spiral form somewhat like a stretched coil spring (forming a helix). The N-H group of each amino acid unit and the fourth C=O group following it along the chain, establishes the N–H---O hydrogen bonds. WitrynaThe hydrogen bonding in alpha helices stabilizes the formation of a rigid cylinder of amino acids. In a beta pleated sheet (shown below) the hydrogen bonded partners might be very far away from each other in the primary structure of the protein (i.e., the 15th and 100th amino acids in the chain) but the secondary structure holds these amino ...
