Title: With reference to membrane proteins, discuss the important role of water in defining the shape and function of biomolecules. Water plays an important role in defining biomolecules shape and function because it possesses some unique properties. Among these properties the ability to form hydrogen bond and hydrophobic effect contribute most to the shape and function determination of biomolecules. Water is a polar molecule. The hydrogen atoms take on a slight positive charge and the oxygen atom takes on a slight negative charge due to unequal sharing of electrons. A hydrogen bond is an interaction between a covalently bonded hydrogen atom on a donor group and a pair of nonbonded electrons on an acceptor group. Water itself also form H-bond between the adjacent water molecules in order to add stability. Molecules with groups capable of forming H-bond and readily dissolves in water are called hydrophilic. Due to the polar...
