CBDC icon on the digital futuristic blue pixelated background. Central Bank Digital Currency.  3d render with bright colors.
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.

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.

Bacterial dehalogenases remove halogen atoms from organic compounds. The one shown here is a reductive dehalogenase from PDB entry 4ur0. It uses a cobamide cofactor (orange) and iron-sulfur clusters to reduce the substrate. Dehalogenases may be used as a way to clean up areas polluted with halogenated compounds.

The pale lactose nonfermenting bacterie (blue arrow) are Salminella typhi.  Salmonella in general does not ferment lactose (colorless colonies),  Salmonella typhi,unlike other salmonallae, produce little hydrogen sulfide (H2S) gas.  The resulting bacterial colonies will appear colorless with colorless or very discrete black centers.
