Uridine is widely used in biochemical and medical research due to its role as a precursor in RNA synthesis. It supports cellular energy transfer and is involved in the formation of glycolipids and glycoproteins. In therapeutic applications, uridine is studied for its potential neuroprotective effects, particularly in improving cognitive function and supporting brain health. It is also used in combination with other nucleosides in antiviral and anticancer drug development. In cell culture, uridine is added to growth media to support the proliferation of certain cell types, especially in uridine-auxotrophic strains. Additionally, it plays a role in metabolic studies and is used in supplements aimed at supporting mitochondrial function and reducing fatigue.
