+====== 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.
