Chemical biology description

Hence the flow of each chapter of this book will lead from a description of specific chemical/biological processes and systems to the identification of the main state variables and processes occurring within the boundaries of the system, as well as the interaction between the system and its surrounding environment. The necessary system processes and interactions are then expressed mathematically in terms of state variables and parameters in the form of equations. These equations may most simply be algebraic or transcendental, or they may involve functional, differential, or matrix equations in finitely many variables. 

As an analytical spectroscopic technique, EPR is similar in concept to the more widely used nuclear magnetic resonance (NMR) spectroscopy [see NMR Overview of Applications in Chemical Biology]. In fact, EPR and NMR are complementary to each other. Both techniques detect magnetic moments, hut NMR determines the chemical stmctures in solution, whereas EPR describes more precisely the electronic and chemical structures of a particular region of the biological system, such as electron transfer centers, metal ions, and an intermediate state of the enzyme or substrate. It is not possible to present a full description of the theory of EPR in an article with this scope. Therefore, only sufficient information is provided here to enable the readers to understand the practical aspects of this analytical tool in enzymology. 

The sensors proposed and used for contamination avoidance should have utility in decontamination. The committee is not aware, however, of any assessment aimed at finding out how well the sensors developed for contamination avoidance can support decontamination and resumption of operations. There are also opportunities to leverage sensor investments with water and food safety. The DOD development of a sensor for water safety (joint chemical/biological agent water monitor) is at an early stage, with planned entry into development in FY 2005. Several references provide descriptions and status reports of biological point detection systems within the DOD.1 Table C.2 offers a summary. 

By offering an overview of chemical biology clarified by detailed examples and descriptions of important techniques, it is the aim of this book to stimulate young chemical biologists and inform them of the opportunities to apply the power of chemistry to important problems in biology. 

Future Directions. Hofiftnann (2) wrote in 1982, It is hoped that in the course of time enough analysis will be done to confirm relationships between analysis and response to specific treatments. In 1987, Grattan and Clarke (7) stated, We are able to analyse wood chemically and give it a detailed biological description, but at present it is very difficult, except in the most general terms, to understand what this predicts for the treatment. ...
