A ball and stick model of a molecule of Human Interferon. Interferons are proteins important in the working of the immune system and are produced in large numbers in the presence of viruses, bacteria, tumors and parasites.  Interferons are used in drugs to combat cancer, multiple sclerosis, hepatitis B and C and other diseases. Isolated on white.

A ball and stick model of a Polytetrafluoroethylene molecule, also known as PTFE or most commonly Teflon. It is a polymer consisting of only carbon and fluorine atoms. It is used as a non-stick coating for cookware, as a lubricant, and it is also used to contain highly reactive chemicals as it is extremely non-reactive.

After dopamine binding, the dopamine receptor changes his shape and binds the inactive G protein.The G protein expels its GDP molecule replacing it by GTP. and falls into two pieces. The Galpha subunit binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.
