The spectra of radicals formed upon the addition of .OH radicals to the 3 position of substrates for p-hydroxybenzoate hydroxylase (4-hydroxybenzoic acid, 2,4-dihydroxybenzoic acid, and 4-aminobenzoic acid) have been determined using pulse radiolysis combined with the results from high performance

Combined optical and conductimetric measurements in aqueous solution indicate that at high pH (greater than or equal to 10).OH radicals react with the phenoxide form of 2,4-dihydroxybenzoic acid to form transiently phenoxyl radicals and a small amount of hydroxyeyclohexadienyl (HCHD)

By using a Raman microscope, we show that it is possible to probe the conformational states in protein crystals and crystal fragments under growth conditions (in hanging drops). The flavin cofactor in the enzyme para-hydroxybenzoate hydroxylase can assume two conformations:

A rapid, simple reversed-phase high-performance liquid chromatographic method with ultraviolet absorbance detection has been developed for the determination of calcium dobesilate in human plasma. Sample processing is based on an ion-pairing extraction with tetra-n-butylammonium hydroxide as cationic pairing ion and
