d-fructose-13c-6

D-Fructose-13C6 can be used as an internal standard for the quantification of D-fructose by GC- or LC-MS.

2-deoxy-D-Glucose-13C is intended for use as an internal standard for the quantification of 2-deoxy-D-glucose by GC- or LC-MS. 2-deoxy-D-Glucose is a glucose antimetabolite and an inhibitor of glycolysis. It inhibits hexokinase, the enzyme that converts glucose to glucose-6-phosphate, as well as phosphoglucose isomerase, the enzyme that converts glucose-6-phosphate to fructose-6-phosphate.
