α-D-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. Glucose 1-phosphate belongs to the class of organic compounds known as monosaccharide phosphates. These are monosaccharides comprising a phosphated group linked to the carbohydrate unit. Glucose 1-phosphate is the direct product of the reaction in which glycogen phosphorylase cleaves off a molecule of glucose from a greater glycogen structure. It cannot travel down many metabolic pathways and must be interconverted by the enzyme phosphoglucomutase in order to become glucose 6-phosphate. Free glucose 1-phosphate can also react with UTP to form UDP-glucose. It can then return to the greater glycogen structure via glycogen synthase. *Found widely in both plants and animals. A precursor of starch in plants and of glycogen in animals. [CCD] Acquisition and generation of the data is financially supported in part by CREST/JST.

3-Dehydro-L-gulonate 6-phosphate
3-Dehydro-L-gulonate 6-phosphate is an intermediate in the metabolic pathways of glucose metabolism. Its chemical structure is characterized by a hexose sugar backbone with specific modifications. The "3-Dehydro" part of its name indicates the presence of a double bond at the third carbon atom due to the removal of two hydrogen atoms, which differentiates it from the corresponding sugar. The "L-gulonate" portion refers to its derivation from L-gulonic acid, a sugar acid. The "6-phosphate" indicates the presence of a phosphate group attached to the sixth carbon atom of the sugar. Biologically, 3-Dehydro-L-gulonate 6-phosphate plays a role in the metabolism of glucose. It is involved in the process of gluconeogenesis, which is the synthesis of glucose from non-carbohydrate sources, such as amino acids and glycerol. This pathway is particularly important during periods of fasting or low carbohydrate intake, where the body needs to maintain blood glucose levels for energy production. Additionally, 3-Dehydro-L-gulonate 6-phosphate may also be involved in other metabolic pathways, including the pentose phosphate pathway, which is important for the production of NADPH (an important reducing agent in the cell) and ribose-5-phosphate (a precursor for nucleotide synthesis). In summary, 3-Dehydro-L-gulonate 6-phosphate is a chemically modified sugar phosphate that serves as an intermediate in various metabolic pathways, particularly in the synthesis and breakdown of glucose. Its presence and regulation are crucial for maintaining energy balance and providing necessary building blocks for cellular processes in living organisms.
D-Xylulose-5-phosphate
Xylulose 5-phosphate (Xu-5-P) is a metabolite of the hexose monophosphate pathway that activates protein phosphatase 2A to mediate the acute effects of carbohydrate feeding on the glycolytic pathway, as well as the coordinate long-term control of the enzymes required for fatty acid and triglyceride synthesis. Xu-5-P is the signal for the coordinated control of lipogenesis. Feeding carbohydrate causes levels of liver glucose, Glucose-6-phosphate (Glc-6-P), and Fructose-6-phosphate (Fru-6-P) to rise. Elevation of Fru-6-P leads to elevation of Xu-5-P in reactions catalyzed by the near-equilibrium isomerases of the nonoxidative portion of the hexose monophosphate pathway (ribulose 5-phosphate (Ru5P) epimerase [EC 5.1.3.1], ribose 5-phosphate (Rib5P) isomerase [EC 5.3.1.6], transaldolase [EC 2.2.1.2], and transketolase [EC 2.2.1.1]). The elevation of Xu-5-P is the coordinating signal that both acutely activates phosphofructokinase [PFK; EC 2.7.1.11] in glycolysis and promotes the action of the transcription factor carbohydrate responsive element binding protein (ChREBP) to increase transcription of the genes for the enzymes of lipogenesis, the hexose monophosphate shunt, and glycolysis, all of which are required for the de novo synthesis of fat.
