And so if there's a build up of the galactose, an enzyme known as Aldos reductase will use this molecule and the H plus ion to transform this sugar molecule into an alcohol known as galactitol. Now, galactitol, if there's a build up of galactitol in certain areas of our body, that can cause very, very dangerous conditions. So the high concentration of galactose and subsequent high concentrations of the alcohol, galactitol is toxic to the body and it can actually cause damage to many areas of our body. For instance, it can cause liver enlargement, it can cause damage to our liver, and that eventually might actually progress to cirrhosis. And cirrhosis is basically a very advanced form of liver damage. It can also cause, cause cataract formation, delayed mental development, ovarian failure, and a feeling of laziness or lack of enthusiasm and so forth.
