Enzyme
Enzymes are proteins that catalyze chemical reactions. In enzymatic reactions, the molecules at the beginning of the process, called substrates, are converted into different molecules, called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates...
in the pentose phosphate pathway
Pentose phosphate pathway
The pentose phosphate pathway is a process that generates NADPH and pentoses . There are two distinct phases in the pathway. The first is the oxidative phase, in which NADPH is generated, and the second is the non-oxidative synthesis of 5-carbon sugars...

6-Phosphogluconolactone
6-Phosphogluconolactone is an intermediate in the pentose phosphate pathway.It is produced from glucose-6-phosphate by glucose-6-phosphate dehydrogenase.-See also:* Lactone...

6-Phosphogluconate
6-Phosphogluconic acid is an intermediate in the pentose phosphate pathway and the Entner–Doudoroff pathway.It is formed by 6-phosphogluconolactonase, and acted upon by phosphogluconate dehydrogenase to produce ribulose 5-phosphate. It may also be acted upon by 6-phosphogluconate dehydratase to...
