Indoleamine 2,3 dioxygenase 1 (IDO1) protein. Tryptophan catabolic enzyme of the kynurenine pathway. 3D illustration.
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.

Abstract geometric shape
Cholera toxin, molecular model. Cholera toxin (choleragen) is a protein complex secreted by the bacterium Vibrio cholerae, that causes the disease cholera. It is made up of a wedge-shaped A subunit (right part of illustration) and five B subunits (left part of illustration) that form a ring which binds to the intestinal lining. In its most severe forms, cholera is one of the most rapidly fatal illnesses known.
