Comparative Determination of Xenobiotics Adsorption

Immunochemical determination of xenobiotics with endocrine disrupting effects.

This paper is a review with more than 100 references discussing the immunochemical methods reported in the literature for the most important man-made chemicals with suspected endocrine disrupting activity. Details regarding immunizing hapten design, antibody production, and the features (limit of detection, dynamic range, specificity) of the most important immunochemical methods developed (ELIS...

Determination of Adsorption Isotherm for L-Lysine Imprinted Polymer

The optimization of adsorption-based operations requires an accurate model to represent the separation process. In the present study, single-component adsorption data of L-lysine on its imprinted polymer were fitted to Freundlich, Langmuir-type and Jovanovic-type models. L-Lysine imprinted polymer (LLIP) was prepared by free radical solution polymerization. The best estimate of the parameters o...

Microbial transformation of xenobiotics

Introduction The term xenobiotic (Greek xenos + bioticos, which means “strange” and “life-related” respectively) means a chemical substance that is not a natural component of a living organism exposed to it, i.e. a strange, exogenous substance or anthropogenic material. This definition covers substances strange to the target organisms, hence its use for most poisons and drugs. An important grou...

Co-oxidation of xenobiotics.

Co-oxidation of xenobiotics has been shown t o occur during prostaglandin synthase (PGS)-catalysed synthesis of prostaglandins (Marnett. 198 I ; EIing et al.. 1983; Marnett & Eling. 1983). PGS catalyses the oxygenation of polyunsaturated fatty acids to hydroxy endoperoxides (e.g. PGH2). The most important substrate in vivo is arachidonic acid (AA) . PGS contains two activities: the fatty acid c...
