Book excerpt: LA COMPREHENSION DES MECANISMES DU REPLIEMENT ET DE LA DENATURATION EST UN ASPECT ESSENTIEL DE LA CHIMIE DES PROTEINES. ELLE EST INDISPENSABLE A L'ETABLISSEMENT DE CE QU'ON APPELLE PARFOIS LE DEUXIEME CODE GENETIQUE, RELIANT LA STRUCTURE PRIMAIRE D'UNE PROTEINE A SA STRUCTURE TRIDIMENSIONNELLE. L'INTERET, SUSCITE PAR CES PROCESSUS A ETE AMPLIFIE PAR LES RECENTES DECOUVERTES SUR LES IMPLICATIONS MEDICALES QUE PEUT AVOIR LE REPLIEMENT ANORMALE D'UNE PROTEINE. BIEN QUE LES AGENTS DENATURANTS CHIMIQUES NE SOIENT PAS IMPLIQUES DANS LE PHENOMENE DE DENATURATION A L'INTERIEUR DE LA CELLULE, ILS SONT FREQUEMMENT UTILISES DANS LES ETUDES DU REPLIEMENT DES PROTEINES, CE QUI JUSTIFIE L'ETUDE DE LEUR MODE D'ACTION. CE TRAVAIL PORTE SUR L'ETUDE DES INTERACTIONS PROTEINES/AGENTS DENATURANTS A L'ETAT CRISTALLIN. LES TRAVAUX ONT ETE REALISES SUR 2 PROTEINES : LA BARNASE ET LE LYSOZYME, EN PRESENCE DE DIFFERENTS AGENTS DENATURANTS : UREE, CHLORURE DE GUANIDIUM, THIOUREE, BROMOETHANOL ET SDS. AFIN D'EFFECTUER UNE ETUDE STRUCTURALE A HAUTE RESOLUTION EN PRESENCE DE FORTES CONCENTRATIONS EN AGENTS DENATURANTS, LES CRISTAUX ONT ETE PREALABLEMENT RETICULES A L'AIDE DU GLUTARALDEHYDE. AU TOTAL, 7 COMPLEXES BARNASE-AGENTS DENATURANTS ET 5 COMPLEXES LYSOZYME-AGENTS DENATURANTS ONT PU ETRE AFFINES A DES RESOLUTIONS COMPRISES ENTRE 1.6 ET 2A. L'ANALYSE DE CES STRUCTURES A PERMIS (I) DE MONTRER QUE LES 2 PROTEINES SUBISSAIENT PEU DE MODIFICATIONS STRUCTURALES POUR LES CONCENTRATIONS ETUDIEES, ET (II) DE DETERMINER LES DIFFERENTS SITES DE FIXATION DE CES AGENTS SUR LA BARNASE ET LE LYSOZYME, ET DE CARACTERISER LEURS INTERACTIONS. LES RESULTATS OBTENUS MONTRENT QUE POUR LES CONCENTRATIONS ETUDIEES LES SITES DE FIXATION DE CES AGENTS SONT PEU NOMBREUX ET TOUS SITUES A LA SURFACE DE LA PROTEINE. LES INTERACTIONS SE FONT PRINCIPALEMENT VIA DES LIAISONS HYDROGENE AU NIVEAU DE LA CHAINE PRINCIPALE ET DES CHAINES LATERALES POLAIRES ; NEANMOINS QUELQUES INTERACTIONS HYDROPHOBES SONT OBSERVEES. CES RESULTATS SONT EN ACCORD AVEC DES ETUDES SIMILAIRES REALISEES PAR CRISTALLOGRAPHIE OU RMN PAR D'AUTRES AUTEURS, PARALLELEMENT A NOTRE TRAVAIL. DANS LE CAS DE LA BARNASE, NOUS AVONS PU COMPARER NOS RESULTATS AVEC CEUX OBTENUS PAR DYNAMIQUE MOLECULAIRE SUR LA DENATURATION DE CETTE PROTEINE EN PRESENCE D'UREE, ET CONCLURE A UNE BONNE CORRELATION.

Available in PDF, EPUB and Kindle. Book excerpt: Food chemistry is the study of chemical processes and interactions of all biological and non-biological components of foods. The biological substances include such items as meat, poultry, lettuce, beer, and milk as examples. It is similar to biochemistry in its main components such as carbohydrates, lipids, and protein, but it also includes areas such as water, vitamins, minerals, enzymes, food additives, flavours, and colours. This discipline also encompasses how products change under certain food processing techniques and ways either to enhance or to prevent them from happening. An example of enhancing a process would be to encourage fermentation of dairy products with lactic acid; an example of a preventing process would be stopping the Maillard reaction on the surface of freshly cut Red Delicious apples whether by hand or mechanical methods. This book presents the recent research from around the world in this field.

Available in PDF, EPUB and Kindle. Book excerpt: Helmut Sigel, Astrid Sigel and Roland K.O. Sigel, in close cooperation with John Wiley & Sons, launch a new Series “Metal Ions in Life Sciences”. The philosophy of the Series is based on the one successfully applied to a previous series published by another publisher, but the move from “biological systems” to “life sciences” will open the aims and scope and allow for the publication of books touching on the interface between chemistry, biology, pharmacology, biochemistry and medicine. Volume 2 focuses on the vibrant research area concerning nickel as well as its complexes and their role in Nature. With more than 2,800 references and over 130 illustrations, it is an essential resource for scientists working in the wide range from inorganic biochemistry all the way through to medicine. In 17 stimulating chapters, written by 47 internationally recognized experts, Nickel and Its Surprising Impact in Nature highlights critically the biogeochemistry of nickel, its role in the environment, in plants and cyanobacteria, as well as for the gastric pathogen Helicobacter pylori, for gene expression and carcinogenensis. In addition, it covers the complex-forming properties of nickel with amino acids, peptides, phosphates, nucleotides, and nucleic acids. The volume also provides sophisticated insights in the recent progress made in understanding the role of nickel in enzymes such as ureases, hydrogenases, superoxide dismutases, acireductone dioxygenases, acetyl-coenzyme A synthases, carbon monoxide dehydrogenases, methyl-coenzyme M reductases...and it reveals the chaperones of nickel metabolism.

Available in PDF, EPUB and Kindle. Book excerpt: Proteins are the servants of life. They occur in all com- nent parts of living organisms and are staggering in their fu- tional variety, despite their chemical similarity. Even the simplest single-cell organism contains a thousand different p- teins, fulfilling a wide range of life-supporting roles. Additions to the total number of known proteins are being made on an increasing scale through the discovery of mutant strains or their production by genetic manipulation. The total international protein literature could fill a medi- sized building and is growing at an ever-increasing rate. The reader might be forgiven for asking whether yet another book on proteins, their properties, and functions can serve a useful purpose. An explanation of the origin of this book may serve as justification. The authors form the tutorial team for an int- sive postexperience course on protein characterization or- nized by the Center for Professional Advancement, East Brunswick, New Jersey, an educational foundation. The course was first mounted in Amsterdam in 1982 and has since been repeated several times, in both Amsterdam and the US, with participants from North America and most European countries. In a predecessor to this book, emphasis was placed on the role of protein isolation in the food industry, because at the time this reflected the interests of most of the participants at the course. Today, isolated proteins for food use are extracted from yeasts, fungal sources, legumes, oilseeds, cereals, and leaves.

Metallochemistry of Neurodegeneration: Biological, Chemical and Genetic Aspects discusses the rapidly developing area of metals in the nervous system and their role in neurodegenerative disease, such as Alzheimer's, Parkinson's and prion diseases. Written by leading experts in their fields, each chapter combines elements of genetics, biochemistry and biological inorganic chemistry in its discussion. The book highlights the differences in pathologies of neurodegenerative diseases but also discusses the mechanistic similarities. Sections include: metal ions and prion diseases; metal ions and Alzheimer disease; manganese in brain functioning; metal involvement in Parkinson disease; Cu-Zn superoxide dismutase and familial amyotrophic lateral sclerosis. This book will appeal to both chemists and biologists at the post graduate and research level.

Book excerpt: This first edited Volume on IgY-Technology, addresses the historical and dynamic development of IgY-applications. The authors cover the biological basis and theoretical context, methodological guidance, and applications of IgY-Technology. A focus is laid on the use of IgY-antibodies for prophylactic/therapeutic purposes in human and veterinary medicine. Aside from applications, the chapters also offer an evolutionary understanding of the IgY molecule, IgY receptors and practical prerequisites to produce IgY-antibodies. Guidance is given for every step of the process. Starting with an introduction to hens as a model species and including hen husbandry, hen egg-laying capacity and total IgY outcomes. Readers will also learn about immunization techniques, the advantages and limitations of different IgY extraction methods, as well as storage stability of the final product. The last part of the volume highlights hands-on aspects of applications, such as IgY delivery strategies, new methods to produce monoclonal IgY-antibodies or production of functional IgY fragments by phage-display as well as commercial exploitation of the technology. Thus, this book is a valuable resource and guide for Scientists, Clinicians and Health Product Developers in both human and veterinary medicine.
