... of the chemical reactions that occur in organism require material dissolved in water. The high H-bonding capacity allow it to act a non-electrolytes and dissolve polar compound such as glucose in the body. Water can also act as electrolytes due to the high capacity of hydration shells and high dielectric constant. This allows inorganic ionic material such as NaCl to become hydrated and dissolve in water. It can also act as polyelectrolytes where particles are in a colloidal suspension by hydrated surface ionic charge and an example of this is globular proteins. Substances like lipid which are nonpolar and nonionic are not able to form hydrogen bonds with water and therefore they show very limited solubility in water. These substances are called hydrophobic. They form a clathrate structure where all the hydrophobic molecules tends to cluster together in order to reduce the entropy of the mixture. Most of these biomolecules ...
