Hydrogen bonding is important in many chemical processes. Hydrogen bonding is responsible for water's unique solvent capabilities. Hydrogen bonds hold complementary strands of DNA together, and they are responsible for determining the three-dimensional structure of folded proteins including enzymes and antibodies.
A hydrogen-bond donor includes the hydrogen atom and the atom to which it is most tightly linked with. The hydrogen-bond also play a very important roles in proteins' structure because it stabulizes the secondary, tertiary and quaternary structure of proteins which formed by alpha helix, beta sheets, turns and loops.
