 Context examples 

While NADH is produced in mitochondria by the Kreb's cycle, NADPH is produced through a pathway called the pentose phosphate pathway.

A pentose which is an epimer at C-2 of ribose (in Fisher projection).

(Arabinose, NCI Thesaurus/CRCH)

Binding of insulin to its receptor stimulates glucose uptake, accelerates both glycolysis and the pentose phosphate cycle and increases glycogen synthesis in the liver.

(Insulin, NCI Thesaurus)

The pentose phosphate pathway is a process of glucose turnover that produces NADPH as reducing equivalents and pentoses as essential parts of nucleotides.

(Pentose Phosphate Cycle Pathway, NCI Thesaurus/KEGG)

This protein plays a role in pentose metabolism to produce NADPH.

(Glucose-6-Phosphate 1-Dehydrogenase, NCI Thesaurus)

(Epiandrosterone, NCI Thesaurus)

Nucleotide Synthesis Alteration involves a change in the quality of the existing state of activities of biologic molecules or complexes involved in the enzymatic formation of nucleoside phosphates, the monomeric building blocks from which DNA or RNA polymers are constructed that consist of a purine or pyrimidine base, a pentose sugar, and a phosphate group.

(Nucleotide Synthesis Alteration, NCI Thesaurus)

(Oxidative Reactions of the Pentose Phosphate Pathway, NCI Thesaurus/BIOCARTA)

The first portion of the pentose phosphate pathway involves the oxidation of glucose in three steps, with the concomitant production of NADPH.
