Abstract
A study of the biosynthesis of digitoxose and D-glucose in the purpurea glycosides A and B of Digitalis purpurea leaves by feeding 14C-labeled D-glucose, D-fructose, D-mannose and D-galactose demonstrated that D-glucose was the most effective precursor of digitoxose in these glycosides. Degradation of the labeled digitoxose and D-glucose indicated that D-glucose was directly transformed to this ...
Abstract
A study of the biosynthesis of digitoxose and D-glucose in the purpurea glycosides A and B of Digitalis purpurea leaves by feeding 14C-labeled D-glucose, D-fructose, D-mannose and D-galactose demonstrated that D-glucose was the most effective precursor of digitoxose in these glycosides. Degradation of the labeled digitoxose and D-glucose indicated that D-glucose was directly transformed to this 2,6-dideoxy sugar and to the bound D-glucose of the glycosides without essential rearrangement to its carbon skeleton.
