Prostaglandin D2 or PGD2 is a prostaglandin that binds to the receptor PTGDR as well as CRTH2. 3d illustration
3d model of testosterone molecule.
3d structure of Danazol, a synthetic steroid that is used primarily in the treatment of endometriosis and marketed widely throughout the world. It is the derivative of ethisterone.
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.
