Book excerpt: The Porphyrins, Volume III: Physical Chemistry, Part A deals with the physical chemistry of porphyrins, their precursors, catabolic derivatives, and related systems. The book covers electronic structure and spectroscopy including circular dichroism and magnetic circular dichroism as well as electronic, infrared, resonance Raman, and Zeeman spectroscopy. Porphyrin stereochemistry, X-ray crystallography, and mass spectroscopy are also included. This volume is organized into 12 chapters and begins with an overview of the optical absorption and emission spectra of porphyrins and the theory by which these facts are understood. The discussion then shifts to the electronic states of the iron porphyrin complex in various heme proteins as displayed by the light absorption properties in the visible region of the electromagnetic spectrum. The reader is methodically introduced to the electronic absorption spectra and molecular orbital theory of chlorophylls, the magnetic optical activity of porphyrins and hemoproteins, and circular dichroism studies of hemoproteins. The book also examines the mass spectra and infrared spectroscopy of porphyrins, resonance Raman scattering from metalloporphyrins and hemoproteins, and photographic essay of porphyrins and related macrocycles. It then concludes with a chapter on high-resolution Zeeman spectroscopy of metalloporphyrins. This book should be useful to inorganic, organic, physical, and biochemists interested in the physical chemistry of porphyrins.
Download or read book DNA Conjugates and Sensors written by Keith R Fox and published by Royal Society of Chemistry. This book was released on 2012-11-30 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applications of nucleic acids have developed recently to provide solutions for biosensors, diagnostic tools and as platforms for the assembly of complex structures. These developments have been possible as their base sequence can be used to assemble precise structures following simple and predictable rules. Self-assembled DNA can then be amplified using polymerase chain reaction (PCR) and this ultimately enables the preparation of synthetic nucleic acids. Their use as molecular tools or DNA-conjugates has recently been enhanced by the addition of other groups including enzymes, fluorophores and small molecules. Written by leaders in the field, this volume describes the preparation and application of these DNA-conjugates. Several have been used as sensors (aptamers, riboswitches and nanostructures) based on the ability of nucleic acids to adopt specific structures in the presence of ligands, whilst others link reporter groups such as proteins or fluorophores to RNA or DNA for detection, single molecule studies, and increasing the sensitivity of PCR. The book is relevant to researchers in areas related to analytical chemistry, chemical biology, medicinal chemistry, molecular pharmacology, and structural and molecular biology.

Download or read book Circular Dichroism and Linear Dichroism written by Alison Rodger and published by Oxford University Press, USA. This book was released on 1997 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an introduction to all those who wish to use the complementary spectroscopic techniques of optical activity (circular dichroism, CD) and optical anisotropy (linear dichroism, LD) for the study of the structure of molecules and interactions between molecules in solution. It emphasizes these techniques and how to use them for both low and high molecular weight molecules. The book begins by describing the principles behind CD and LD and how these techniques can be used in the laboratory without using advanced maths or quantum mechanics. The next chapters describe how both techniques may be applied to the study of biological macromolecules and give a detailed description of how they may be used on small molecules to investigate molecular and electronic structure. The final part contains theoretical derivations of all the equations required for the applications described previously. Specific molecular examples are used to illustrate concepts and to show the reader how to use the techniques in chemical and biological systems. Circular Dichroism and Linear Dichroism is an easy guide to what a prospective user of CD needs to know and explains how LD is not merely an exotic technique only to be practiced by experienced spectroscopists, but may be routinely and usefully employed as an aid to molecular structure determination.
Download or read book Chemical Science of Electron Systems written by Takeshi Akasaka and published by Springer. This book was released on 2015-11-05 with total page 765 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the most advanced review available of all aspects of π-electron systems, including novel structures, new synthetic protocols, chemical and physical properties, spectroscopic and computational insights, molecular engineering, device properties and physiological properties. π-Electron systems are ubiquitous in nature. Plants convert light energy into chemical energy by photosynthetic processes, in which chlorophylls and other porphyrinoids play an important role. On the one hand, research to learn about photosynthesis from nature has led to understanding of electron and energy transfer processes and to achieving artificial energy conversion systems inspired by nature. On the other hand, recent advances in organic and inorganic chemistry make it possible to construct novel π-electron systems that had never existed in nature. The authors of this book are from a variety of research fields including organic chemistry, inorganic chemistry, physical chemistry, materials science, and biology, providing a comprehensive overview of π-electron systems for a broad readership. Not only specialists but also graduate students working in π-electron systems will find the book of great interest. Throughout, the diverse potential for future fruitful applications of π-electron systems is revealed to the reader.

Available in PDF, EPUB and Kindle. Book excerpt: Albumin Structure, Function and Uses reviews the many facets of serum albumin, including its history and evolutionary development, structure and function, synthesis, degradation, distribution and transport, and metabolic behavior. The use, misuse, and abuse of albumin in the treatment of disease are also discussed. This book is comprised of 17 chapters and begins with a commentary on how albumin is used, misused, and abused in the treatment of disease such as peptic ulcer, and a description of the real indications for its use. Concepts in albumin purification are then examined, along with the amino acid sequence of serum albumin and some aspects of its structure and conformational properties. Subsequent chapters explore the phylogenetics of albumin; albumin binding sites; clinical implications of drug-albumin interaction; genetics of human serum albumin; and hepatic synthesis of export proteins. Albumin catabolism and intracellular transport are also considered, together with surgical and clinical aspects of albumin metabolism. This monograph should be a useful resource for biochemists and clinicians.

Download or read book Circular Dichroism and Magnetic Circular Dichroism Spectroscopy for Organic Chemists written by Nagao Kobayashi and published by Royal Society of Chemistry. This book was released on 2012 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: CD and MCD spectroscopy can provide key information about the conformations and electronic states of chromophore containing molecules. However, the theory has remained too challenging and inaccessible for many organic chemists and biochemists and only a few researchers have carried out detailed quantitative analyzes of their spectral data. This is not surprising as people who excel at spectroscopic theory usually lack the skills set required to design and synthesize the molecules that would be most appropriate for describing and explaining the theory of CD and MCD spectroscopy. Most of the books that have been written on the subject have, therefore, been based on very dense sets of mathematical equations. This timely book rectifies that situation by summarizing the relationship between the different types of spectra and by describing in detail the qualitative and quantitative methods which can readily be used to analyze CD and MCD spectral data. During the last decade the authors have successfully synthesized several molecules to illustrate key points related to the theory of CD and MCD spectroscopy, resulting in this definitive book providing key practical knowledge in a readily accessible style. It is aimed primarily at organic chemists and biochemists and provides the required reading for researchers active in the field. In the introduction, the book describes the types of information that can be derived from CD and MCD spectroscopy. After a detailed explanation of the theory of electronic absorption spectroscopy, it then provides practical in depth examples of the various analytical methods that can be carried out with CD and MCD spectral data. This makes the theory of these techniques much more accessible for researchers who do not specialize in physical chemistry.
