The Weak Hydrogen Bond
Author: Gautam R. Desiraju
language: en
Publisher: International Union of Crystal
Release Date: 2001
The weak or non-conventional hydrogen bond has been subject of intense scrutiny over recent years in several fields, in particular in structural chemistry, structural biology, and also in the pharmaceutical sciences. There is today a large body of experimental and theoretical evidence confirming that hydrogen bonds like C-H...O, N-H...pi, C-H...pi and even bonds like O-H...metal play distinctive roles in molecular recognition, guiding molecular association, and in determining molecular and supramolecular architectures. The relevant compound classes include organometallic complexes, organic and bio-organic systems, and also DNA and proteins. The book provides a comprehensive assessment of this interaction type, and is of interest to all those interested in structural and supramolecular science, including fields as crystal engineering and drug design.
Physics, Pharmacology and Physiology for Anaesthetists
Author: Matthew E. Cross
language: en
Publisher: Cambridge University Press
Release Date: 2008-03-27
The FRCA examination relies in part on a sound understanding of the basic sciences (physics, physiology, pharmacology and statistics) behind anaesthetic practice. It is important to be able to describe these principles clearly, particularly in the viva section of the examination. This book provides the reader with all the important graphs, definitions and equations which may be covered in the examination, together with clear and concise explanations of how to present them to the examiner and why they are important. Particular attention is paid to teaching the reader how to draw the graphs. This is an aspect of the examination which can be overlooked but which, if done well, can create a much better impression in the viva situation. Packed full of precise, clear diagrams with well structured explanations, and with all key definitions, derivations and statistics, this is an essential study aid for all FRCA examination candidates.
Hydrogen Bonding in Biological Structures
Author: George A. Jeffrey
language: en
Publisher: Springer Science & Business Media
Release Date: 2012-12-06
Hydrogen bonds are weak attractions, with a binding strength less than one-tenth that of a normal covalent bond. However, hydrogen bonds are of extraordinary importance; without them all wooden structures would collapse, cement would crumble, oceans would vaporize, and all living things would disintegrate into random dispersions of inert matter. Hydrogen Bonding in Biological Structures is informative and eminently usable. It is, in a sense, a Rosetta stone that unlocks a wealth of information from the language of crystallography and makes it accessible to all scientists. (From a book review of Kenneth M. Harmon, Science 1992)
