Biochemical model

The X-ray crystal structures of many of these complexes have now been determined representative examples are. shown in Fig. 4.11 from which it is clear that, at least for the larger cations, coordinative saturation and bond rhrectionality are far less significant factors than in many transition element complexes. Further interest in these ligands stems from their use in biochemical modelling since they sometimes mimic the behaviour of naturally occurring, neutral, macrocydic antibiotics such as valinomycin, monactin, nonactin, nigericin...

Ronald Breslow (Co-Chair) is University Professor of Chemistry, Columbia University, and a founder of a new pharmaceutical company. He received his B.A. (1952), M.A. (1954), and Ph.D. (1955) from Harvard University. His research area is organic chemistry with specialization in biochemical model systems, biomimetic synthetic methods, reaction mechanisms, and aromaticity and antiaromaticity. He served as president of the American Chemical Society in 1996 and has authored a book for the general public, Chemistry Today and Tomorrow The Central, Useful, and Creative Science. He is a member of the National Academy of Sciences, the American Academy of Arts and Sciences, and the American Philosophical Society. He received the U.S. National Medal of Science in 1991. 

Considerable use has been made of the thermodynamic perturbation and thermodynamic integration methods in biochemical modelling, calculating the relative Gibbs energies of binding of inhibitors of biological macromolecules (e.g. proteins) with the aid of suitable thermodynamic cycles. Some applications to materials are described by Alfe et al. [11].

The description of single enzyme activity in chemical reactions, together with the activity of other biomolecules, is typical for biochemical models of alkaloid biogenesis. There is no contradiction between chemical and biochemical, which serve to enrich one another. In many cases, typical chemical and biochemical models are unified in papers today ". ... 

The biochemical model contains the pathways of the enzymatic reactions in the synthetic routes. Model can be constructed for each alkaloid. Eigure 75 presents biochemistry model of Catharantus alkaloids. The most important enzymes on this model are TDC (tryptophan decarbocylase), GlOH (geraniol 10-hydroxylase) and SS (strictoside synthase). NADPH+, PO (Peroxidase), O (oxidase) and NADH+ are all active in different Catharantus alkaloid formations. The biochemical models are subject to both qualitative and quantitative alkaloid...

There is a general trend in biochemistry toward more quantitative and sophisticated interpretations of experimental data. As a result, demand for accurate, complex, and elaborate calculation increases. Recent progress in computer technology, along with the synergy of increased need for complex biochemical models coupled with an improvement in software programs capable of meeting this need, has led to the birth of computational biochemistry (Bryce, 1992 Tsai, 2000). 

Both Copasi and XPP comply with the SBML standard for exchange of biochemical models. The SBML-based PharmBiosim approach combines the above simulation-based strategy with the application of algorithms based on continuation and bifurcation analysis from applied mathematics.
