Osmotic pressure depends on the number of particles dissolved in a solution and not on the nature of such particles. Mineral salts, glucose, proteins and urea are the main regulating particles for the osmolarity of an organism. These molecules, along with other particles inside and outside the cell, generate a larger or smaller osmotic gradient between the intracellular and extracellular space.
