2.3 CHEMICAL REACTIVITY FROM ITS LEWIS STRUCTURE 2.3 CHEMICAL REACTIVITY FROM ITS LEWIS STRUCTURE AND FORMAL CHARGEAND FORMAL CHARGE

1,4-B is converted to GHB by the human body. It makes it’s way though the digestive system and is absorbed into the blood stream. From there it circulates until making contact with the liver, which uses an enzyme called dehydrogenase (the same one used to break down alcohol) to convert the 1,4-B into a substance called aldehyde gamma-hydroxybutyraldehyde, which is released back into the blood stream. When the aldehyde gamma-hydroxybutyraldehyde comes back around to the liver, an enzyme called aldehyde dehydrogenase oxidizes it, creating GHB, which is then released into the bloodstream to do its work.

• Enviromental Consideration :Enviromental Consideration :If released to air,1,4-butanediol will exist solely as a

vapor in the atmosphere. Vapor-phase 1,4-butanediol will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals.1,4-Butanediol does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight.
