The formation and decay of veratryl alcohol radical cation upon oxidation of veratryl alcohol by thallium (II) ions was studied by pulse radiolysis with spectrophotometric and conductometric detection. In aqueous solution at pH 3 the radical cation decays by a

Poly R478, 4-methoxymandelic acid and oxalic acid were oxidized by lignin peroxidase (LiP) in the presence of the fungal metabolite 2-chloro-1,4-dimethoxybenzene (2Cl-14DMB), whereas no oxidation occurred in the absence of 2Cl-14DMB. These substrates clearly inhibited the consumption of 2Cl-14DMB and

The mechanism of veratryl alcohol-mediated oxidation of 4-methoxymandelic acid by lignin peroxidase was studied by kinetic methods. For monomethoxylated substrates not directly oxidized by lignin peroxidase, veratryl alcohol has been proposed to act as a redox mediator. Our previous study

The chromatographic retention mechanism describing relationship between retention factor and concentration of Cu(2+) (l-phenylalanine)2 using chiral ligand mobile phase was investigated and eight mandelic acid derivatives were enantioseparated by chiral ligand exchange chromatography. The relationship between retention factor and concentration

A new liquid chromatographic method has been developed for the chiral separation of the enantiomers of mandelic acid and their derivatives 2-chloromandelic acid, 4-hydroxymandelic acid, 4-methoxymandelic acid, and 3,4,5-trismethoxymandelic acid. The enantiomers were separated by a CHIRALPAK(®) IC (250 mm×4.6

The enantioselectivity of neutral single-isomer synthetic precursors of sulfated-β-cyclodextrins was studied. Four neutral single-isomer cyclodextrins substituted on the secondary side with acetyl and/or methyl functional groups, heptakis(2-O-methyl-3,6-dihydroxy)-β-cyclodextrin (HM-β-CD), heptakis(2,3-di-O-acetyl-6-hydroxy)-β-cyclodextrin (HDA-β-CD), heptakis(2,3-di-O-methyl-6-hydroxy)-β-cyclodextrin (HDM-β-CD), heptakis(2-O-methyl-3-O-acetyl-6-hydroxy)-β-cyclodextrin (HMA-β-CD), and their sulfated analogs the negatively

Lignin peroxidase (LiP), an extracellular heme enzyme from the lignin-degrading fungus Phanerochaete chrysosporium, catalyzes the H2O2-dependent oxidation of a variety of nonphenolic lignin model compounds. The oxidation of monomethoxylated lignin model compounds, such as anisyl alcohol (AA), and the role
