In the cation of the title compound, C16H26NO2 (+)·C6HCl2O4 (-)·C4H8O2, the 1-hy-droxy-cyclo-hexyl ring adopts a slightly distorted chair conformation. The dihedral angle between the mean planes of the 1-hy-droxy-cyclo-hexyl and 4-hy-droxy-phenyl rings is 84.0 (8)°. In the anion, the hydroxyl H atom is twisted slightly out of the ring plane with a C-C-O-H torsion angle of -171.9°. Disorder was ...
Conversion of carbohydrate into 5-hydroxymethylfurfural (5- HMF), a versatile, key renewable platform compound is regarded as an important transformation in biomass-derived carbohydrate chemistry. A variety of ILs, not only acidic but also alkaline ILs, were synthesized and used as catalyst in the production of 5-HMF from disaccharide. Several factors including reaction temperature, IL dosage, ...
We studied transport and binding to intact chloroplasts of 10 mutants in three regions of the transit peptide of a precursor to the small subunit of ribulose 1,5-bisphosphate carboxylase/oxygenase [3-phospho-D-glycerate carboxy-lyase (transphosphorylating), E.C.4.1.1.39]. Transport was assayed in a reconstituted system using isolated pea chloroplasts and radioactively labeled precursor. Binding...
Emerging data suggest an important role for cytosine methylation in tumorigenesis. Simultaneously, recent studies indicate a significant contribution of endogenous oxidative DNA damage to the development of human disease. Oxidation of the 5-methyl group of 5-methylcytosine (5mC) residues in DNA results in the formation of 5-(hydroxymethyl)cytosine (hmC). The biological consequences ofhmC residu...
Oxidation of the thymine methyl group can generate 5-formyluracil (FoU), which is known to be both mutagenic and chemically unstable in DNA. Synthetic oligonucleotides containing FoU at defined sites have been prepared to investigate potential mechanisms by which FoU might perturb DNA function. The half-life of the glycosidic bond of an FoU residue in single-stranded DNA under physiological con...
