Download or read book Advances in BioChirality written by C. Zucchi and published by Elsevier. This book was released on 1999-09-08 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chirality is a fundamental, persistent, but often overlooked feature of all living organisms on the molecular level as well as on the macroscopic scale. The high degree of preference for only one of two possible mirror image forms in Nature, often called biological homochirality is a puzzling, and not yet fully understood, phenomenon. This book covers biological homochirality from an interdisciplinary approach - contributions range from synthetic chemists, theoretical topologists and physicists, from palaeontologists and biologists to space scientists and representatives of the pharmaceutical and materials industries. Topics covered include - theory of biochirality, origins of biochirality, autocatalysis with amplification of chirality, macroscopic (present) biochirality, fossil records of chiral organisms - paleochirality, extraterrestrial origin of chirality, exceptions to the rule of biological homochirality, D-amino acids, chemical transfer of chirality, PV effects, and polarised radiation chemistry.

Download or read book Asymmetry in Biological Homochirality written by David Hochberg and published by MDPI. This book was released on 2021-06-04 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chirality, or handedness, is a fundamental physical characteristic, which spans the length scales ranging from elementary particles to the chiral asymmetry of spiral galaxies. The way in which chirality in chemistry, or molecular handedness, may have emerged in a primitive terrestrial environment, and how it can be triggered, amplified, and transferred, are deeply challenging problems rooted in both fundamental scientific interests and the technological potentials for science and society. Chirality constitutes a unifying feature of the living world and is a prime driving force for molecular selection and genetic evolution in biology. In this book, we offer a selection of five distinct approaches to this problem by leading experts in the field. The selected topics range from protein chirality and its relevance to protein ageing, protein aggregation and neurodegeneration, entropy production associated with chiral symmetry breaking in closed systems, chiral oscillations in polymerization models involving higher-order oligomers, the mirror symmetry breaking in liquids and its implications for the development of homochirality in abiogenesis, the role of chirality in the chemical sciences, and some philosophical implications of chirality.

Available in PDF, EPUB and Kindle. Book excerpt: This book collects recent advances in the field of nonlinear dynamics in biological systems. Focusing on medical applications as well as more fundamental questions in biochemistry, it presents recent findings in areas such as control in chemically driven reaction-diffusion systems, electrical wave propagation through heart tissue, neural network growth, chiral symmetry breaking in polymers and mechanochemical pattern formation in the cytoplasm, particularly in the context of cardiac cells. It is a compilation of works, including contributions from international scientists who attended the “2nd BCAM Workshop on Nonlinear Dynamics in Biological Systems,” held at the Basque Center for Applied Mathematics, Bilbao in September 2016. Embracing diverse disciplines and using multidisciplinary approaches – including theoretical concepts, simulations and experiments – these contributions highlight the nonlinear nature of biological systems in order to be able to reproduce their complex behavior. Edited by the conference organizers and featuring results that represent recent findings and not necessarily those presented at the conference, the book appeals to applied mathematicians, biophysicists and computational biologists.

Download or read book Alkaloids Chemical and Biological Perspectives written by S.W. Pelletier and published by Elsevier. This book was released on 2001-12-03 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alkaloids: Chemical and Biological Perspectives, the 15th volume of the ACBP series, features four important reviews of research on alkaloids. Chapter 1 is the first comprehensive review of the carbon-13 and proton NMR shift assignments and physical constants of diterpene alkaloids and their derivatives. In addition to the catalogue of spectral and physical data, the chapter includes a table of the occurrences of these alkaloids in various plant species, tables containing molecular formulas versus calculated high-resolution mass values, and calculated high-resolution mass values versus the molecular formulas of diterpenoid alkaloids, as well as seven tables summarizing the carbon-13 chemical shifts of various functional groups in diterpenoid alkaloids. Chapter 2 is a fascinating review of the supercritical fluid extraction of alkaloids. This technique using basic modifiers, provides an alternative method for the extraction of alkaloids. Chapter 3 summarizes recent advances in the synthesis of Amaryllidaceae alkaloids, an important class of naturally-occurring bases and neutral compounds. The increased activity in the synthesis of these alkaloids over the last decade is undoubtedly due to the fact that certain members of this family possess interesting and useful biological properties. Elegant syntheses, chiral and otherwise, of structures incorporating many asymmetric centres are reviewed. Chapter 4 reviews radical cyclization reactions in the total synthesis of indole alkaloids. The use of free radical chemistry in the synthesis of alkaloids has grown markedly because of the mild reaction conditions, tolerance of a wide variety of functional groups, and the good stereoselectivities. Each chapter in this volume has been reviewed by at least one specialist in the field.

Download or read book The New Avenues in Bioinformatics written by Joseph Seckbach and published by Springer Science & Business Media. This book was released on 2007-11-12 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioinformatics has ignited the imagination of scientists, entrepreneurs and the general public. At the meeting place of two fast growth disciplines, biology and computer science Bioinformatics is one of the cornerstones of the new biology. It is clearly pivotal to the translation of high throughput projects such the human genome project into useful knowledge. Yet despite all this attention, there is no consensus on what exactly is Bioinformatics. There are several canonical topics, such as gene structure prediction, protein functional classification or structure prediction. The present book explores new frontiers in bioinformatics, such as Glycomics or the computational modeling of genetic processes. We also discuss confounding factors that we find crucial to the development of the field, such as the ability to protect and restrict intellectual property in the field, or the challenges involved in educating bioinformatics users. Finally, we touch upon some fundamental questions, such as what information is and how it is captured in biological systems. By bringing to the readers such a broad spectrum of reviews, we hope to capture the vibrant spirit of this young science and to truly represent the fast pace with which it is still developing.

Download or read book Supramolecular Structure and Function written by Greta Pifat-Mrzljak and published by Springer Science & Business Media. This book was released on 2013-03-12 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past decade we have witnessed not only an increase in knowledge of the "traditional" biophysical problems, but also an understanding of the molecular basis of various biological phenomena. The principles and methods of biophysics now provide an underpin ning of all of the basic biosciences and are the rational language for discussion between scientists of different disciplines. The International School on Biophysics Supramolecular Structure and Function held in Dubrovnik in September 1984 had as its goal to provide comprehensive discussions on a large number of subjects both for younger scientists at the doctoral or postdoctoral level interested in the molecular nature of fundamental biological entities, and for experienced scientists wishing to gain a broader insight into molecular structures and functions. The topics discussed at the School were inter- and intramolecular interactions in biological systems, and the structure, organization, and function of biological macromolecules and supramolecular assemblies. A number of topics were centered around either a biological problem or a physical technique, sometimes giving an unbalanced view of the field under discussion. Some of the topics required previous knowledge of basic biophysical principles, which were then applied to gain greater insight into the molecular functions of diverse supramolecular systems. Although not all the lectures could be prepared for publication in this volume, I hope that it contains valuable up-to-date information on various aspects of the molecular basis of life.
