An enzyme involved in fructose metabolism is:
Enzymes involved in phase II of glycolysis are used in fructose metabolism also. Glyceraldehyde-3-P Dehydrogenase is an enzyme of phase II of glycolysis. But Phase I enzymes of glycolysis are different for glucose & different for fructose. Aldolase A is in glycolysis Aldolase B is in fructose metabolism Fructose metabolism characterstics Organ: Liver mainly Source: Disaccharide - sucrose (contains equal amount of glucose and fructose), in monosaccharide form i.e. Fructose in Fruits, Honey and high fructose corn syrup (55% fructose, 45% glucose), Sugarcane Fructose entry into cells is insulin independent Fructose ingestion does not leads to insulin release Major source of energy for sperms (present in seminal fluid)
