WebJul 18, 2014 · Many neutrally charged molecules can easily pass through the cell membranes where organophosphates on the other hand are charged species and hence cannot pass through the cell membranes. Thus, biomolecules can be retained within the cellular boundaries if these are charged species i.e., phosphates [2,5]. WebIn contrast to the water-soluble nutrients, lipid-soluble nutrients can diffuse through the plasma membrane. Once inside the cell, they are packaged for transport via the base of the cell and then enter the lacteals of the villi to be transported by lymphatic vessels to the systemic circulation via the thoracic duct.
