Question
One pathway for the metabolism of D-glucose- 6 -phosphate is its enzyme-catalyzed conversion to $\mathrm{D}$ -fructose 6-phosphate. Show that this transformation can be regarded as two enzyme-catalyzed keto-enol tautomerizations (Section 16.5).
Step 1
This is a keto-enol tautomerization, where the aldehyde group of glucose-6-phosphate (a carbonyl group on an end carbon, or 'keto' form) is converted to a keto group (a carbonyl group not on an end carbon) in fructose-6-phosphate. Show more…

One pathway for the metabolism of D-glucose6 -phosphate is its enzyme-catalyzed conversion to D-fructose 6-phosphate. Show that this transformation can be regarded as two enzyme-catalyzed keto-enol tautomerizations (Section $17-5$ ).
One step in glycolysis, the pathway that converts glucose to pyruvate (Section 27.2 ), involves an enzymecatalyzed conversion of dihydroxyacetone phosphate to D-glyceraldehyde-3-phosphate. Show that this transformation can be regarded as two enzyme-catalyzed keto-enol tautomerizations (Section 16.5).
