Cytidine Diphosphate Glucose

	Cytidine Diphosphate Glucose Cytidine diphosphate glucose, often abbreviated CDP-glucose, is a nucleotide-linked sugar consisting of cytidine diphosphate and glucose. Biosynthesis CDP-glucose is produced from CTP and glucose-1-phosphate by the enzyme glucose-1-phosphate cytidylyltransferase. References {{Nucleotide sugars Biochemistry Nucleotides ...

	Cytidine Triphosphate Cytidine triphosphate (CTP) is a pyrimidine nucleoside triphosphate. CTP, much like ATP, consists of a ribose sugar, and three phosphate groups. The major difference between the two molecules is the base used, which in CTP is cytosine. CTP is a substrate in the synthesis of RNA. CTP is a high-energy molecule similar to ATP, but its role as an energy coupler is limited to a much smaller subset of metabolic reactions. CTP is a coenzyme in metabolic reactions like the synthesis of glycerophospholipids, where it is used for activation and transfer of diacylglycerol and lipid head groups, and glycosylation of proteins. CTP acts as an inhibitor of the enzyme aspartate carbamoyltransferase, which is used in pyrimidine biosynthesis.Blackburn, G. Michael. ''Nucleic Acids in Chemistry and Biology''.

	Glucose-1-phosphate Glucose 1-phosphate (also called cori ester) is a glucose molecule with a phosphate group on the 1'-carbon. It can exist in either the α- or β-anomeric form. Reactions of α-glucose 1-phosphate Catabolic In glycogenolysis, it is the direct product of the reaction in which glycogen phosphorylase cleaves off a molecule of glucose from a greater glycogen structure. A deficiency of muscle glycogen phosphorylase is known as glycogen storage disease type V (McArdle Disease). To be utilized in cellular catabolism it must first be converted to glucose 6-phosphate by the enzyme phosphoglucomutase in a free equilibrium. One reason that cells form glucose 1-phosphate instead of glucose during glycogen breakdown is that the very polar phosphorylated glucose cannot leave the cell membrane and so is marked for intracellular catabolism. Phosphoglucomutase-1 deficiency is known as glycogen storage disease type 14 (GSD XIV). Anabolic In glycogenesis, free glucose 1-phosphate can also react wi ...

	Glucose-1-phosphate Cytidylyltransferase In enzymology, a glucose-1-phosphate cytidylyltransferase () is an enzyme that catalyzes the chemical reaction :CTP + alpha-D-glucose 1-phosphate \rightleftharpoons diphosphate + CDP-glucose Thus, the two substrates of this enzyme are CTP and alpha-D-glucose 1-phosphate, whereas its two products are diphosphate and CDP-glucose. This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing nucleotide groups ( nucleotidyltransferases). The systematic name of this enzyme class is CTP:alpha-D-glucose-1-phosphate cytidylyltransferase. Other names in common use include CDP glucose pyrophosphorylase, cytidine diphosphoglucose pyrophosphorylase, cytidine diphosphate glucose pyrophosphorylase, cytidine diphosphate-D-glucose pyrophosphorylase, and CTP:D-glucose-1-phosphate cytidylyltransferase. This enzyme participates in starch and sucrose metabolism Starch or amylum is a polymeric carbohydrate consisting of numerous glucose units ...

picture info	Biochemistry Biochemistry or biological chemistry is the study of chemical processes within and relating to living organisms. A sub-discipline of both chemistry and biology, biochemistry may be divided into three fields: structural biology, enzymology and metabolism. Over the last decades of the 20th century, biochemistry has become successful at explaining living processes through these three disciplines. Almost all areas of the life sciences are being uncovered and developed through biochemical methodology and research. Voet (2005), p. 3. Biochemistry focuses on understanding the chemical basis which allows biological molecules to give rise to the processes that occur within living cells and between cells,Karp (2009), p. 2. in turn relating greatly to the understanding of tissues and organs, as well as organism structure and function.Miller (2012). p. 62. Biochemistry is closely related to molecular biology, which is the study of the molecular mechanisms of biological phenomena.As ...
