Aliases: Uracil riboside, Uridine monophosphate (UMP)
Pyrimidine nucleoside — salvaged by uridine-cytidine kinase (UCK1/2) to UMP, then UDP / UTP. Crosses BBB via ENT1/2. Incorporated into phosphatidylcholine and phosphatidylethanolamine via the Kennedy pathway; proposed membrane-phospholipid-turnover mechanism behind mood / cognitive effects in small RCTs. Often stacked with DHA + choline ('MIND' formulation in Alzheimer's research).
