Application

D-Tagatose 6-phophate is a metabolite in the biosynthetic pathway converting galactose 6-phosphate to pyruvate. D-Tagatose 6-phosphate is a substrate for tagatose-6-phosphate kinase which converts it into D-tagatose 1,6-bisphosphate with the transfer of a phosphate from ATP.

Biochem/physiol Actions

An enzyme substrate for D-tagatose-6-phosphate kinase, and key metabolite of the tagatose-6-phosphate pathway linking D-galactose-6-phosphate with D-glyceraldehyde-3-phosphate.

Packaging
