Common NameUtp
DescriptionUridine triphosphate, also known as 5'-UTP or UTP, belongs to the class of organic compounds known as pyrimidine ribonucleoside triphosphates. These are pyrimidine ribobucleotides with triphosphate group linked to the ribose moiety. More specifically, UTP is a pyrimidine nucleoside triphosphate, consisting of the organic base uracil linked to the 1′ carbon of the ribose sugar, and esterified with tri-phosphoric acid at the 5′ position. Uridine triphosphate exists in all living species, ranging from bacteria to plants to humans. The main role of UTP is as substrate for the synthesis of RNA during transcription. UTP is the precursor for the production of CTP via the enzyme known as CTP Synthetase. UTP can be biosynthesized from UDP by the enzyme known as nucleoside diphosphate kinase by using phosphate group from ATP. UTP also has the role of a source of energy or an activator of substrates in a variety of metabolic reactions. For instance UTP can be used to activate Glucose-1-phosphate, leading to the formation of UDP-glucose and inorganic phosphate. The resulting UDP-glucose can be used in the synthesis of glycogen. UTP is also used in the metabolism of galactose, where the activated form of galactose, called UDP-galactose can be converted to UDP-glucose. UDP-glucuronate, another product of UTP reacting with glucuronic acid, is a sugar used in the creation of polysaccharides and is an intermediate in the biosynthesis of ascorbic acid (except in primates and guinea pigs).
