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.

Overhead aerial drone view of oyster farm racks at low tide, flying at a low altitude to be able to see the detail of the oyster racks and seaweed. Located in a tidal estuary in Sutherland, Scotland. the low tides enable workers to access the racks for turning the oysters as they grow. Oysters have been farmed for many hundreds of years using this method. Seaweed has grown around the metal lines of racks.

After dopamine binding, the dopamine receptor changes his shape and binds the inactive G protein.The G protein expels its GDP molecule replacing it by GTP. and falls into two pieces. The Galpha subunit binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.
