Description

Ribose-5-phosphate (R5P) is a key intermediate in the pentose phosphate pathway (PPP), a metabolic route that diverges from glycolysis. It is synthesized from glucose-6-phosphate through a series of enzymatic reactions, specifically via the oxidative phase of the PPP. R5P plays a critical role in nucleotide biosynthesis, serving as a precursor for the synthesis of purine and pyrimidine bases, which are essential components of DNA and RNA. It also contributes to NADPH production, which is essential for reducing oxidative stress and supporting biosynthesis processes. The PPP and its associated R5P production are crucial for cell growth and proliferation, particularly in rapidly dividing cells. R5P is also involved in the synthesis of other essential biomolecules, such as coenzymes like NAD and FAD. Extensive research on R5P focuses on its role in metabolism, its potential therapeutic implications in conditions related to nucleotide metabolism and oxidative stress, and its involvement in cell signaling pathways.'
