描述
D-xylulose-1-phosphate is produced in the hepatocytes and is the product of fructokinase (Ketohexokinase, EC 2.7.1.3) phosphorylation of D-xylulose. The cleavage of D-xylulose-1-phosphateglycolaldehyde by aldolase (fructose-bisphosphate aldolase, EC 4.1.2.13) produces glycolaldehyde which is an oxalate precursor. The distribution of both enzymes in human tissues indicates that this reaction sequence occurs mainly in the liver, to a lesser extent in the kidney, and very little in heart, brain and muscle. The kinetic properties of fructokinase show that this enzyme can phosphorylate D-xylulose as readily as D-fructose. (PMID: 6458298, 13898172, 6284103, 2996495) [HMDB]. D-Xylulose 1-phosphate is found in many foods, some of which are mentha (mint), onion-family vegetables, nance, and malus (crab apple).
