1-Aminopentane is an organic compound with the formula CH 3 (CH 2) 4 NH 2. It is used as a solvent , as a raw material in the manufacture of a variety of other compounds, including dyes, emulsifiers , and pharmaceutical products, [ 1 ] and as a flavoring agent .
In enzymology, a glucose-1-phosphate phosphodismutase (EC 2.7.1.41) is an enzyme that catalyzes the chemical reaction 2 D-glucose 1-phosphate ⇌ D-glucose + D-glucose 1,6-bisphosphate Hence, this enzyme has one substrate , D-glucose 1-phosphate , and two products , D-glucose and D-glucose 1,6-bisphosphate .
The pentose phosphate pathway (also called the phosphogluconate pathway and the hexose monophosphate shunt or HMP shunt) is a metabolic pathway parallel to glycolysis. [1] It generates NADPH and pentoses (five- carbon sugars ) as well as ribose 5-phosphate , a precursor for the synthesis of nucleotides . [ 1 ]
The first step of this reaction is phosphorylation of the substrate via phosphotransferase during transport. In the case of glucose, the product of this phosphorylation is glucose-6-phosphate (Glc-6P). Due to the negative charge of the phosphate, this Glc-6P can no longer freely leave the cell.
The reaction catalysed by an enzyme uses exactly the same reactants and produces exactly the same products as the uncatalysed reaction. Like other catalysts, enzymes do not alter the position of equilibrium between substrates and products. [1] However, unlike uncatalysed chemical reactions, enzyme-catalysed reactions display saturation kinetics.
The enzyme glucose-1-phosphatase (EC 3.1.3.10) catalyzes the reaction α-D-glucose 1-phosphate + H 2 O D-glucose + phosphate. This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds. The systematic name is α-D-glucose-1-phosphate phosphohydrolase.

[1] [2] [3] 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). [4]
