Its main missions are multiple and intimately linked: Energy metabolism: glucose management (storage as glycogen, release as needed), regulation of certain lipids, synthesis of plasma proteins Storage: vitamins (A, D, B12), minerals and energy reserves Transformation: metabolism of molecules from food, the environment, and medications Bile production: key role in lipid digestion and elimination of certain waste products Bile is produced by the liver and then released into the intestine, often via the gallbladder , which stores and concentrates it

Figure 2 4.1 Passive diffusion Small nanoparticles move down their concentration gradients by a mechanism of transport known as passive diffusion, which is a nonspecific and energy-free mode of transport ( 4.2 Efflux pumps ATP hydrolysing proteins embedded in the endothelial membranes also facilitate the transfer of molecules across the BBB using the energy generated from ATP breakdown
