Describe the structural basis of the "blood-brain barrier" and list two characteristics of a drug that
e.g., like alcohol or lipid soluble or possess a structure allowing it to bind to a transport protein to be carried across these lipid membranes.

The Answer is would allow it to pass through the BBB.
A .The cells comprising the capillaries that provide blood to the brain are tightly packed together, with minimal pores between them.In addition, parts of glial cells may cover the outside of the capillaries.These comprise a lipid barrier through which non-lipid soluble drugs cannot pass, unless the molecules are compatible with transport proteins that can carry them across these membranes.Thus, in order to penetrate this barrier, the molecule must be small and nonionized, e.g., like alcohol or lipid soluble or possess a structure allowing it to bind to a transport protein to be carried across these lipid membranes.
