 +====== Hydrogen Bond =======
 +
 +A hydrogen bond is a polar interaction between two electronegative atoms, a donor and an
 +acceptor. In proteins hydrogen bonds involving the main chain oxygen and amide are critical
 +in forming the secondary structures. The polar side chains also form hydrogen bonds.
 +Energetically it is important to satisfy all hydrogen bond donors and acceptors.
 +In proteins more than 90% of side chain atoms are 'satisfied' by forming
 +hydrogen bonds to protein atoms or solvent.
