Turmeric and the chemical formula of curcumin. Skeletal structure of the keto form of the yellow chemical and principal curcuminoid of turmeric, Curcuma longa. E100, dietary supplement and food color.
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.
A GTP-bound G-alpha protein (blue) binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.
