An example of a metabolic reaction. In the reaction ρ
, a fructose 1,6-bisphosphate (C6H14O12P2) molecule is produced from glycerone phosphate (C3H7O6P) and glyceraldehyde 3-phosphate (C3H7O6P) molecules. Carbon maps are shown with dashed lines. Glyceraldehyde 3-phosphate is equivalent to the gray fragment of fructose 1,6-bisphosphate while glycerone phosphate is equivalent to the white fragment.
