The breaking down of Fructose to help make ATP and joining into the Glycolysis Pathway is done by adding Fructokinase from the liver and making Fructose 1 Phosphate (F-1-P) and then adding Aldolase B and making Dihydroxyacetone Phosphate (DHAP) and Glyceraldehyde. DHAP and Glyceraldehyde goes into the Glycolysis Pathway able to move forward into Pyruvate or backwards up the pathway to make more Glucose depending on what the body is in need of.
Unfortunately, the body can have hereditary fructose intolerance, which means during the break down of Fructose Aldolase B is nonfunctioning causing a buildup of F-1-P and not making DHAP and Glyceraldehyde. Because DHAP and
