GABA B receptors are G protein-coupled receptors, also called metabotropic receptors. Binding of an agonist (baclofen, red) leads to a G-protein coupled C-AMP signaling pathway. Source: PDB entries 7eb2, 6r3q,.

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.
