Estimation of hexose diphosphate

Archives of Biochemistry and Biophysics, 1954
Abstract A new method based on the anthrone reaction is proposed for the quantitative determination of hexose diphosphate in order to eliminate the uncertain fructose equivalent. The method can he used for determination of hexose diphosphate of 5–400 μg. with an experimental error for a duplicate determination of 2.4%.

Different Tastes of Enantiomorphic Hexoses

Science, 1962
Studies of synthetic iron sulfides formed from aqueous solution at 25 degrees C and atmospheric pressure have revealed the existence of a new phase, tetragonal FeS. This phase is formed as the initial corrosion product of metallic iron or steel in solutions of hydrogen sulfide. It has been discovered as an iron corrosion product in the sediments of the

Total Synthesis of the L-Hexoses

Science, 1983
Enantiomerically pure polyhydroxylated natural products are synthesized by using a reiterative two-carbon extension cycle consisting of four steps. The generality and efficiency of this methodology are demonstrated in the total synthesis of all eight L-hexoses.

Hexose-Monophosphate Oxidation

1969
Publisher Summary This chapter describes the hexose-monophosphate oxidation pathway ribose 5-phosphate, which is the most important structural material generated during the operation of the cycle, as it is one of the building blocks for nucleic acid synthesis, in all organisms.

Improved Intestinal Membrane Permeability of Hexose-Quinoline Derivatives via the Hexose Transporter, SGLT1

Journal of Pharmaceutical Sciences, 2008
Intestinal membrane permeability is an important factor affecting the bioavailability of drugs. As a strategy to improve membrane permeability, membrane transporters are useful targets since essential nutrients are absorbed efficiently via specific transporters.

Hexose metabolism in pancreatic islets: Enzyme-to-enzyme tunnelling of hexose 6-phosphates

International Journal of Biochemistry, 1991
The fate of unlabelled D-glucose and D-[2-3H]glucose in pancreatic islets was simulated taking into account experimental values for glycolytic flux, intracellular concentration of D-glucose 6-phosphate and phosphoglucoisomerase activity. The model, which also takes into account the isotopic discrimination in velocity and intramolecular transfer of ...

Role of tomato hexose kinases

Functional Plant Biology, 2007
Hexose phosphorylation is an essential step of sugar metabolism. Only two classes of glucose and fructose phosphorylating enzymes, hexokinases (HXK) and fructokinases (FRK), have been found in plants. Tomato (Lycopersicon esculentum Mill.) is the only plant species from which four HXK and four FRK genes have been identified and characterised.

The chlorella hexose/H+-symporters

2000
The physiology, molecular biology, and biochemistry of the inducible hexose uptake protein of Chlorella kessleri is reviewed. The protein encoded by the HUP1 gene is the most intensively studied membrane transporter of plants. Responsible for substrate accumulation up to 1500-fold, it translocates one proton together with one hexose, and the cell ...
