pentose phosphate pathway

[′pen‚tōs ′fäs‚fāt ′path‚wā]
(biochemistry)
A pathway by which glucose is metabolized or transformed in plants and microorganisms; glucose-6-phosphate is oxidized to 6-phosphogluconic acid, which then undergoes oxidative decarboxylation to form ribulose-5-phosphate, which is ultimately transformed to fructose-6-phosphate.

The activity of GR in first attack and recurrence was lower because of low level of NADPH output in pentose phosphate cycle. In remission there was a significant decrease of NADH-GDG activity, on which the synthesis of glutathione depends.
In this case, the activity of pentose phosphate cycle was 2.5 fold less than that for maximum lysine synthesis.
