Uridine (Undine)

Uridine (Undine) is a nucleoside that contains the pyrimidine base uracil and the pentose ribose.

Uridine plays an important role in RNA biosynthesis, serving as one of the four building blocks of ribonucleotides along with adenosine, guanosine and cytidine. The uracil in uridine forms a glycosidic bond with the 1' carbon atom of ribose.

Uridine can be phosphorylated in the body to form uridine monophosphate (UMP), which is then converted to uridine diphosphate (UDP) and uridine triphosphate (UTP). These phosphorylated uridine derivatives are involved in RNA biosynthesis as substrates.

In addition, uridine plays an important role in carbohydrate metabolism. It can be phosphorylated to uridine diphosphate glucose (UDP-glucose), a key intermediate in the biosynthesis of polysaccharides, glycoproteins and glycolipids.

Thus, uridine is an important compound required for normal cell functioning. Its derivatives play a key role in the biosynthesis of RNA and carbohydrates.

Uridine is an organic compound with the chemical formula C5H8N2O5. The name of the compound comes from two Latin words: ur (urine, urine) and unde (giver), which is why uridine is sometimes called a diuretic nucleotide. This compound contains sugar, but the structure of this compound is different from the structure of ribose.

Uridine is a nucleoside alcohol, it consists of the sugar ribose combined with the nitrogenous base uracil. Like other purines, uracil contains in its structure a nitrogen atom, which is the basis for the life of all animal and plant cells. Therefore, adding such a substance can be dangerous.
