I've already commented once on this chart, but I'd like to
add some context.

The chart shows interactions of glucose and fructose inside
the liver only. Probably there is some text that goes along
with it that would make this clear. The metabolism inside
the muscles, the brain, the reproductive organs, the pancreas
and other organs is different. A complete chart would be
at least ten times as complicated. There really should be
a circle around the central parts showing which reactions
take place in the liver. Galactose is another important
sugar metabolized by the liver that is completely missing
here.

Each of those arrows represents the action of an enzyme
listed in the caption underneath. These enzymes are
specified in our DNA, and their expression can also
be switched on and off by environmental factors. There
are hundreds of these enzymes that vary between individuals.
So each of us metabolizes sugars in a slightly different
way.
