Abstract geometric shape
PETase (left) degrades  polyethylene terephtalate (PET) into monohydroxyethyl terephthalate (MHET) and MHETase degrades MHET ethylene glycol (EG) and terephthalic acid (TPA). The substrates in the binding sites are depicted in red.
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.
Perfluorobutanesulfonic acid fluorosurfactant molecule. 3D rendering. Atoms are represented as spheres with conventional color coding.
Artificial molecular structure in many colors. Horizontal composition, isolated on white background.
