Fructose

Fructose is, as the name suggests, the main sugar in fruit. In the human body, fructose is the primary sugar supplying sperm and adipose cells.
| The first step involves the enzyme Fructokinase, which phosphorylates fructose into Fructose-1-phostphate. As in the glucose pathway, phosphorylation prevents the free movement of fructose through the plasma membrane, ensuring that it remain in the cell.

| The next step splits the molecule, with the catalysis of an aldolase.

DHAP is processed regularly as part of the glycolysis pathway. Glyceraldehyde is processed in the following reaction.
