'''Uridine triphosphate''' is a [[pyrimidine]] [[nucleotide]], consisting of the [[organic base]] [[uracil]] linked to the 1' carbon atom of the sugar [[ribose]], esterified with tri-[[phosphoric acid]] at its 5'-position. Its main role is as substrate for the synthesis of [[RNA]] during [[transcription (genetics)|transcription]].
UTP also has the role of a source of energy or an activator of substrates in metabolic reactions, like that of [[Adenosine Triphosphate|ATP]], but more specific. When UTP activates a substrate, UDP-substrate is usually formed and inorganic phosphate is released.
UDP-glucose enters the synthesis of [[glycogen]]. UTP is used in the metabolism of [[galactose]], where the activated form UDP-galactose is converted to UDP-glucose. UDP-[[glucuronate]] is used to conjugate [[bilirubin]] to a more water soluble [[bilirubin diglucuronide]].
