Pseudouridine, > 98.5%, CAS No. : [1445-07-4]

Pseudouridine is an isomer of the nucleoside uridine in which the uracil is attached via a carbon-carbon instead of a nitrogen-carbon glycosidic bond. Pseudouridine is the most abundant RNA modification in cellular RNA. An isomer of the nucleoside uridine found in all species and in many classes of RNA except mRNA. It is formed by enzymes called synthases, which post-transcriptionally isomerize specific uridine residues in RNA in a process termed pseudouridylation. Studies suggest that Beta-Pseudouridine reduces radiation-induced chromosome aberrations in human lymphocytes.
