Delta endotoxins (δ-endotoxins) are pore-forming toxins produced by Bacillus thuringiensis species of bacteria. They are useful for their insecticidal action and are the primary toxin produced by Bt corn. 3D cartoon and Gaussian surface models, chain instance color scheme, based on PDB 4d8m, white background.
A molecular model of the plasticizer Dibutyl Phthalate or DBP.  As a plasticizer it has been used in many products including adhesives, textiles, cosmetics and children's toys. There are now concerns about its health effects, particularly its effect on male health and behaviour.   Isolated on white.
