Ketohexokinase (KHK) also known as hepatic fructokinase catalyzes the phosphorylation of fructose to fructose-1-phosphate using ATP as phosphate source in the liver. The HKH gene is spliced to HKH-A and the more active HKH-C. HKH deficiency causes the essential fructosuria disorder. KHK acts in the first step of fructose metabolism.
