WebFunction. 6-phosphogluconolactonase catalyzes the conversion of 6-phosphogluconolactone to 6-phosphogluconate, which are two intermediates in the … WebIn all these examples, the total oxidation state of the molecule adds up to 0. On top of that, there is a general trend that O has an OS (Oxidation State) of -2 (usually) and H has an OS of +1 (again, usually). From that, we can calculate the unknown OS of C which tends to vary in these molecules.

We discuss these reactions separately in the next section. The primary functions of the PPP are to produce NADPH (for use in anabolic reductions), ribose-5-phosphate (for making … WebAug 20, 2024 · - The first step of the pentose phosphate pathway is the conversion of glucose-6-phosphate to 6-phosphogluconolactone and generation of NADPH from NADP+. This oxidation-reduction coupled reaction is catalyzed by the enzyme glucose-6-phosphate dehydrogenase (G6PD). G6PD is a rate-limiting enzyme of the pentose phosphate pathway.
