Uses
A nucleotide that is a major component of ribonucleic acid. It is found in dietary supplements as well as natural RNA rich foods and has been shown to increase cognitive function in animals.
Application
Uridine 5′-monophosphate disodium salt can be used as a cross-linking agent to prepare thermosensitive chitosan hydrogels containing graphene oxide as nanofillers. The hydrogels are attractive materials for use as scaffolds for the regeneration of damaged tissues[3].
benefits
Membrane phospholipids like phosphatidylcholine (PC) are required for cellular growth and repair, specifically for synaptic function. PC synthesis is controlled by cellular levels of its precursor, cytidine-5'-diphosphate choline (CDP-choline), which is produced from cytidine triphosphate (CTP) and phosphocholine. In rat PC12 cells, exogenous uridine was shown to elevate intracellular CDP-choline levels by promoting the synthesis of uridine triphosphate (UTP), which was partly converted to CTP. In such cells, uridine also enhances the neurite outgrowth produced by the nerve growth factor (NGF). A study assessed the effect of dietary supplementation with uridine-5'-monophosphate disodium (UMP-2Na+, an additive in infant milk formulas) on striatal dopamine (DA) release in aged rats. Potassium (K+)-evoked DA release was significantly greater among UMP-treated rats, i.e., 341+/-21% of basal levels vs. 283+/-9% of basal levels in control rats (p<0.05); basal DA release was unchanged. The levels of neurofilament-70 and neurofilament-M proteins, biomarkers of neurite outgrowth, increased to 182+/-25% (p<0.05) and 221+/-34% (p<0.01) of control values, respectively, with UMP consumption. Hence, UMP treatment not only enhances membrane phosphatide production but also can modulate two membrane-dependent processes, neurotransmitter release and neurite outgrowth, in vivo[2].
General Description
Uridine 5′-monophosphate is a pyrimidine mononucleotide. It is formed by decarboxylation of orotidine 5′-monophosphate. UMP is further converted to UTP (uridine 5′-triphosphate) using kinases.
Biological Activity
Uridine 5′-monophosphate disodium salt is the sodium salt form of uridine monophosphate (UMP). UMP serves as a key intermediate in the biosynthesis of pyrimidine nucleotides within the body; it can be sequentially phosphorylated by kinases to form UDP and UTP, which participate in RNA biosynthesis, the activation of sugars, and the synthesis of polysaccharides. Furthermore, UTP can drive glycogen synthesis and act as a carrier for sugar nucleotides, facilitating the modification of glycoproteins and glycolipids.
