Abstract
The Hydrophobicity mean the compounds which insoluble in water i.e., hate the water (not love the water). May be these compounds are lipid soluble, but not actually. This means these compounds may across the cell membrane of the cell. This transport of compounds through, simple diffusion, passive transport (active transport), transport by carrier (amino acids carrier), pinocytosis. And the binding of drugs with tissue (may be receptors or tissue reservoir as (fatty tissue and lipid soluble vitamins) and the carbohydrates (glucose convert to glycogen in the liver).
