˜The œmaillard reaction : chemistry, biology and implications / par Nursten, H.E. Publication : [S.l.] : Royal Society of Chemistry, 2005 . 214 p. ; , Research in the field of the Maillard reaction has developed rapidly in recent years, not only as a result of the application of improved analytical techniques but also the realisation that that the Maillard reaction plays an important role in some human diseases and in the ageing process. The Maillard Reaction : Chemistry, Biochemistry and Implications provides a comprehensive treatise on the Maillard reaction. This single-author volume covers all aspects of the Maillard reaction in a uniform, co-ordinated, and up-to-date manner. The book encompasses: the chemistry of non-enzymic browning; recent advances; colour formation in non-enzymic browning; flavour and off-flavour formation in non-enzymic browning; toxicological aspects; nutritional aspects; other physiological aspects; other consequences of technological significance; implications for other fields; non-enzymic browning due mainly to ascorbic acid; caramelisation; inhibition of non-enzymic browning in foods; and inhibition of the Maillard reaction in vivo. 24 cm.

Biotransformations in organic chemistry : a textbook / par Faber, Kurt. Publication : [S.l.] : Springer, 2004 . 454 p. ; , The use of biocatalysts, employed either as isolated enzymes or whole microbial cells, offers a remarkable arsenal of highly selective transformations for state-of-the-art synthetic organic chemistry. Over the last two decades, this methodology has become an indispensable tool for asymmetric synthesis, not only at the academic level, but also on an industrial scale. This well-established textbook on biocatalysis provides a basis for undergraduate and graduate courses in modern organic chemistry, as well as a condensed introduction into this field. After a basic introduction into the use of biocatalysts ? principles of stereoselective transformations, kinetics and enzyme properties ? the different types of reactions are explained according to the 'reaction principle', such as hydrolysis, reduction, oxidation, C-C bond formation, etc. Special techniques, such as the use of enzymes in organic solvents, immobilization techniques and the use of modified enzymes, are treated in a separate section. A final chapter deals with the basic rules for the safe and practical handling of biocatalysts. In this revised and corrected 5th edition, emphasis has been given to an improved didactic style in order to facilitate a deeper understanding of the underlying principles. New developments, such as dynamic resolution, stereo-inversion and enantio-convergent processes are included. 23 cm.

Peroxiredoxin systems : structures and functions / par Flohé,, Leopold. Publication : [S.l.] : Springer, 2007 . 410 p. ; , The peroxiredoxins represent an important emerging family of sulfhydryl-linked antioxidant proteins, apparently ubiquitously present in all known organisms. The antioxidant function of the peroxiredoxins complements that of other enzymic and non-enzymic systems within the cell. In addition, there is increasing evidence that the peroxiredoxins play a role in cell signalling, by controlling and/or sensing hydrogen peroxide and peroxynitrite levels. In this, the first book containing a broad survey on the peroxiredoxins, the editors succeeded to involve almost all groups that contributed significant insights into the emerging field. The diverse biological roles of the new protein family are discussed in the context of other antioxidant systems like those based on heme or selenium catalysis. Finally, related future perspectives, which range from antimicrobial therapy up to the understanding of human development and carcinogenesis, are highlighted. Specifically, the book will be of outstanding interest to researchers who want to understand how micro-organisms, plants and animals cope with oxidative stress and how such stress is recognized and linked to adaptive responses via redox regulation of cellular processes. 24 cm.

Serial analysis of gene expression.   Publication : [S.l.] : Humana Press, 2007 . 208 p. ; , Serial Analysis of Gene Expression (SAGE): Digital Gene Expression Profiling facilitates the introduction of SAGE into the laboratory, and provides a framework for interpreting and comparing data derived from SAGE experiments. Of the several methods of genetic profiling available, only SAGE measures the expression of both known and unknown genes. SAGE studies encompass 50,000 tags and can provide detailed knowledge of the 2000 most highly expressed genes in the tissue sample. The SAGE protocols presented are detailed, fully annotated, and tested, and are all written by experienced SAGE researchers from around the world. Part 1 is dedicated to experimental procedures of SAGE and related methods including aRNA LongSAGE, SuperSAGE, DeepSAGE, and GMAT. Part 2 provides methods for extraction and filtration of tags, analysis of ditag populations, and completing statistically correct comparisons of gene expression profiles. Comparative transcriptomics enables scientists to understand the underlying genetics of biological changes such as development, disease, crop yield, and resistance. SAGE analysis is also used to obtain unknown tags, which can be used as gene-specific primers in Rapid Amplification of cDNA Ends (RACE) reactions to generate full-length transcripts for cloning and sequencing. This book will be an indispensable tool for any lab engaged in genetic profiling and comparative transcriptomics, and will help many laboratories to successfully implement tag-based sequencing methods and procedures and obtain comprehensive, useful, and interpretative data. 23 cm.
