CYCLOHEXYLAMMONIUM FRUCTOSE-1, 6-DIPHOSPHATES

Mannose 6-, fructose 1-, and fructose 6-phosphates inhibit human natural cell-mediated cytotoxicity.

In vitro human natural cell-mediated cytotoxicity (NCMC) to K-562, Molt-4, and F-265 cells is inhibited in a dose-dependent manner by mannose 6-phosphate, fructose 1-phosphate and fructose 6-phosphate. This inhibition is not observed with mannose, glucose, fucose, glucose 6-phosphate, mannose 1-phosphate, galactose 1-phosphate, or galactose 6-phosphate. Preincubation of the effector cells, obta...

Automated procedure for serum aldolase estimation. Fructose-1, 6-diphosphatase and fructose-1-phosphatase.

SERUM ALDOLASE ESTIMATION 1S one of the principal diagnostic tests used in the elucidation of muscle disease (2-6). In myocardial infarction (7), liver disease (8), and carcinomatosis (9), the serum aldolase estimation is a useful ancillary aid to diagnosis. The usefulness of the test has been enhanced since the differentiation 1)etween muscle and liver aldolase by use of two substrates-fructos...

Fructose - l , 6 - Bisphosphate 1 s an Allosteric Activator of Pyrophosphate : Fructose - 6 - Phosphate 1 - Phosphotransferase ' Tom

The activity of highly purified pyrophosphate:fructose-6-phosphate 1 -phosphotransferase (PFP) from barley (Hordeum vulgare) leaves was studied under conditions where the catalyzed reaction was allowed to approach equilibrium. The activity of PFP was monitored by determining the changes in the levels of fructose-6phosphate, orthophosphate, and fructose-1,6-bisphosphate (Fru1,6-bisP). Under thes...

Bis(cyclohexylammonium) 2,2′-disulfanediyldibenzoate

In the title molecular salt, 2C(6)H(14)N(+)·C(14)H(8)O(4)S(2) (2-), the complete dianion is generated by crystallographic twofold symmetry and a twisted conformation is found [the C-S-S-C torsion angle is 87.13 (2)° and the dihedral angle between the rings is 83.4 (2)°]. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the cations and anions.

The determination of fructose-6-phosphate and fructose-1,6-diphosphate.
