Ions in Water and Biophysical Implications

Ions in Water and Biophysical Implications PDF Author: Yizhak Marcus
Publisher: Springer Science & Business Media
ISBN: 9400746474
Category : Science
Languages : en
Pages : 224

Book Description
Over the past decade, numerous books have attempted to explain ions in aqueous solutions in relation to biophysical phenomena. Ions in Water and Biophysical Implications, from Chaos to Cosmos offers a physicochemical point of view of the spread of this matter and suggests innovative solutions that will challenge the biophysics research establishment. Starting with a throughout discussion of the properties of liquid water, in particular as a structured liquid with an extensive hydrogen bonded structure, the book examines water as a solvent for gases, non-electrolytes, and electrolytes and reviews the properties, sizes and thermodynamics of isolated and aqueous ions, as well as their interactions, including those of polyelectrolytes. The effects of ions on water structure, including those on solvent dynamics and certain thermodynamic quantities, are presented. This volume investigates water surfaces with its vapour, with another liquid, and with a solid, as well as the effects of solutes, including simple ions and the water-miscible non-electrolytes. Surfaces are relevant to biomolecular and colloidal systems and the book discusses briefly surfactants, micelles and vesicles. Finally, the book concludes with a review of the various biophysical implications involving chaotropic and kosmotropic ions in homogeneous solutions and the Hofmeister series for ions concerning biomolecular and colloidal systems and some aspects of protein hydration and K+/Na+ selectivity in ion channels. Ions in Water and Biophysical Implications, from Chaos to Cosmos will appeal to physical chemists, biophysicists, biochemists, as well as to all students and researchers involved in the study of aqueous solutions.

Biophysical Chemistry

Biophysical Chemistry PDF Author: John T. Edsall
Publisher: Academic Press
ISBN: 1483270580
Category : Science
Languages : en
Pages : 716

Book Description
Biophysical Chemistry, Volume I: Thermodynamics, Electrostatics, and the Biological Significance of the Properties of Matter focuses on the biological aspects of the properties of matter, putting emphasis on the chemical elements, water and carbon dioxide, complex molecules, and proteins. The publication first elaborates on biochemistry and geochemistry, water and its biological significance, and the problems of protein structure. Discussions focus on the number of peptide chains in the molecule and nature of terminal groups, latent heat of fusion, characteristics of the amino acids derived from proteins, expansion of water in freezing, and the relative abundance of chemical elements in the universe. The text then takes a look at thermodynamics and the application to polar molecules and ionic solutions of electrostatics, including free energy of a charged sphere, image charges, salting-out effect, expressions for the change of fundamental thermodynamic functions, and chemical potentials. The book examines the conductivity of electrolytes, acid-base equilibria, and polybasic acids, bases, and ampholytes, including proteins. Topics include ionization of cysteine, isoelectric points of polyvalent ampholytes, hemoglobin, nature of acids and bases, measurement of conductivity, electrolytes as conductors, and the moving boundary method of determining transference numbers. The manuscript is a dependable reference for chemists and researchers interested in thermodynamics, electrostatics, and the biological value of the properties of matter.

Computational Pharmaceutics

Computational Pharmaceutics PDF Author: Defang Ouyang
Publisher: John Wiley & Sons
ISBN: 1118573994
Category : Science
Languages : en
Pages : 350

Book Description
Molecular modeling techniques have been widely used in drug discovery fields for rational drug design and compound screening. Now these techniques are used to model or mimic the behavior of molecules, and help us study formulation at the molecular level. Computational pharmaceutics enables us to understand the mechanism of drug delivery, and to develop new drug delivery systems. The book discusses the modeling of different drug delivery systems, including cyclodextrins, solid dispersions, polymorphism prediction, dendrimer-based delivery systems, surfactant-based micelle, polymeric drug delivery systems, liposome, protein/peptide formulations, non-viral gene delivery systems, drug-protein binding, silica nanoparticles, carbon nanotube-based drug delivery systems, diamond nanoparticles and layered double hydroxides (LDHs) drug delivery systems. Although there are a number of existing books about rational drug design with molecular modeling techniques, these techniques still look mysterious and daunting for pharmaceutical scientists. This book fills the gap between pharmaceutics and molecular modeling, and presents a systematic and overall introduction to computational pharmaceutics. It covers all introductory, advanced and specialist levels. It provides a totally different perspective to pharmaceutical scientists, and will greatly facilitate the development of pharmaceutics. It also helps computational chemists to look for the important questions in the drug delivery field. This book is included in the Advances in Pharmaceutical Technology book series.
