uridine

 [u´rĭ-dēn]
a ribonucleoside containing uracil.
uridine diphosphate (UDP) a nucleotide that participates in glycogen metabolism and in some processes of nucleic acid synthesis.

u·ri·dine (Urd),

(yūr'i-dēn),
Uracil ribonucleoside; one of the major nucleosides in RNAs; as the pyrophosphate (UDP, UDPG, etc.), uridine is active in sugar metabolism.

uridine

/uri·dine/ (ūr´ĭ-dēn) a pyrimidine nucleoside containing uracil and ribose; it is a component of nucleic acid and its nucleosides are involved in the biosynthesis of polysaccharides. Symbol U.
uridine diphosphate  (UDP) a pyrophosphate-containing nucleotide that serves as a carrier for hexoses, hexosamines, and hexuronic acids in the synthesis of glycogen, glycoproteins, and glycosaminoglycans.
uridine monophosphate  (UMP) uridylic acid; a nucleotide, uridine 5′-phosphate.
uridine triphosphate  (UTP) a nucleotide involved in RNA synthesis.

uridine

(yo͝or′ĭ-dēn′)
n.
A nucleoside, C9H12N2O6, that is composed of uracil and ribose, is a component of RNA, and plays a role in regulating many physiological processes.

uridine

The nucleoside of URACIL found in RNA and other NUCELOTIDES.

uridine

a molecule formed from a combination of a ribose sugar and the RNA base URACIL. Further addition of a phosphate group produces the NUCLEOTIDE.

uridine

a ribonucleoside containing uracil.

uridine diphosphate (UDP)
a nucleotide that participates in glycogen metabolism and in some processes of nucleic acid synthesis.
uridine diphosphoglucuronic acid
one of the incidental products in the glucuronate pathway and an important participant in detoxication processes in the body.
uridine 5′-triphosphate (UTP)
main activated form of pyrimidine bases, involved in the activation of sugars for synthesis and polymerization.
