Phosphogluconolactone

False. D-gluconolactone is produced directly from glucose via glucose oxidase. 6-phosphogluconolactone is an intermediate in the hexose monophosphate pathway. [Pg.360]

Based on the difference in the rate of NADPH production with both glucose-6-phosphate and 6-phosphogluconolactone as substrates and the rate of NADPH production with only 6-phos-phogluconolactone as its substrate (107). [Pg.217]

The oxidative part starts with the oxidation of glucose 6-phosphate by glucose-6-phosphate dehydrogenase. This forms NADPH+H"" for the first time. The second product, 6-phosphogluconolactone, is an intramolecular ester (lactone) of 6-phospho-gluconate. [Pg.152]

In the oxidative phase, glucose 6-phosphate is metabolized by glucose 6-phosphate dehydrogenase (G6PD) to form 6-phosphogluconolactone (Figure 6-3). [Pg.76]

Reactions of the hexose monophosphate pathway. Enzymes numbered above are 1) glucose 6-phosphate dehydrogenase and 6-phosphogluconolactone hydrolase, 2) 6-phosphogluconate dehydrogenase,... [Pg.144]

G6P + G6PDH — 6-phosphogluconolactone + NADPH 2NADPH + GSSG - 2GSH + 2NADP... [Pg.112]

The 6-phosphogluconolactone is unstable, and the ester spontaneously hydrolyzes, although a specific enzyme (lactonase) also catalyzes this reaction (Step 2) ... [Pg.339]

Controlled step is dehydrogenation of glucose 6-phosphate to 6-phosphogluconolactone. [Pg.312]

A. Both A and B produce NADPH, but only A produces 6-phosphogluconolactone. [Pg.184]

Glucose-6-Phosphate + NADP <=> 6-Phosphogluconolactone + NADPH (catalyzed by Glucose-6-Phosphate Dehydrogenase)... [Pg.42]

Ribulose-5-phosphate is a pentose phosphate pathway intermediates produced by 6-phosphogluconate dehydrogenase catalyzed oxidation of 6-phosphogluconolactone. [Pg.685]

Lactonase is an enzyme of the pentose phosphate pathway that catalyzes the reaction below 6-Phosphogluconolactone + H20 <=> 6-Phosphogluconate + H+... [Pg.690]
