CD47 also known as integrin associated protein is a transmembrane protein that in humans is encoded by the CD47 gene. CD47 belongs to the immunoglobulin superfamily and partners with membrane integrins and also binds the ligands thrombospondin-1 and signal-regulatory protein alpha. 3D cartoon and Gaussian surface models, chain id color scheme, based on PDB 2jjt, white background
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.
