Because glucose-6-phosphate (G6P) is a branching point for glucose fate, it is also plausible to expect that glucose is metabolized through either or both of the following pathways: (a) being channeled into the hexose monophosphate shunt pathway due to enhanced G6PDH activity, thereby producing cell reducing power (as NADPH) later used for hepatocyte lipogenesis and replenishing GSH pool, hence providing an additional mechanism to counteract OS [54], and/or (b) G6P being isomerized to fructose6-phosphate (F6P), then oxidized to pyruvate and acetylCoA, and finally entering into the lipid anabolic pathway.
