c-Myc and Max transcription factors bound to DNA. 3D illustration. Atoms shown as spheres with conventional color coding.
A molecular model of Bisphenol A or BPA.  It is a common building block in the production of many epoxy resins and plastics including polycarbonate plastic. As such it is present in a huge range of food packaging and household products. There are now concerns about its health effects, particularly its effect on children, infants and fetuses.   Isolated on white.

3D rendering of a drug molecule
Cediranib cancer drug molecule. 3D rendering. Atoms are represented as spheres with conventional color coding.
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.

Rendered Remdesivir molecule in 3D, an experimental drug from Gilead, used to cure the first case of 2019-nCoV in the United States (for a patient at Seattle, Washington). The model showed accurate atom connection and stereochemistry, which was professionally checked. Color symbols - light blue=carbon, red=oxygen, blue=nitrogen, white=hydrogen, green=phosphorus
Ferric maltol iron deficiency drug molecule. 3D rendering. Atoms are represented as spheres with conventional color coding.
A ball and stick model of Eicosapentaenoic Acid or EPA. It is an omega-3 polyunsaturated fatty acid. It is introduced into the diet by eating oily fish. When it comes to fat, there’s one type you don’t want to cut back on: omega-3 fatty acids. Two crucial ones - EPA and DHA - are primarily found in certain fish.
