Mannitol is a type of sugar alcohol. It is used as a low calorie sweetener as it is poorly absorbed by the intestines. As a medication, it is used to decrease pressure in the eyes, as in glaucoma, and to lower increased intracranial pressure.
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.
