Download or read book Melanin Chemistry Explored by Quantum Mechanics written by Ryo Kishida and published by Springer Nature. This book was released on 2021-04-09 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses recent advances in theoretical–computational studies on the biosynthesis of melanin pigment (melanogenesis). These advances are being driven by the development of high-performance computers, new experimental findings, and extensive work on medical applications involving the control of pigmentation and the treatment of challenging dermatological diseases. Understanding the elementary processes involved in chemical reactions at the atomic scale is important in biochemical reaction design for effective control of the pigmentary system. Accordingly, the book focuses on the elementary steps involved in melanogenesis, which crucially affect the composition of the resulting melanin pigment by means of competitive reactions. The book also addresses reactions analogous to melanogenesis, with a focus on o-quinone reactions, which are especially important for understanding melanogenesis-associated cytotoxicity.

Download or read book Melanin the Master Molecule written by Arturo Solís Herrera and published by Bentham Science Publishers. This book was released on 2018-06-04 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Melanin is a biological molecule associated with pigmentation in humans and animals. However, melanin has been observed to have other functions such as neuroprotection and energy production. In Melanin, the Master Molecule, researchers summarize several decades worth of knowledge on melanin and its physicochemical properties. Nine chapters explain the intrinsic biochemistry of melanin, comparisons with conventional energy producing and respiratory biomolecules, the property of melanin to transform light energy into chemical energy through the dissociation of the water molecule, and the theories of melanin based energy production in the nervous system, the cell nucleus, muscles and the eye, and the role the role of melanin in the context of ageing. The authors also delve into the possibility of melanin being the key molecule needed to spark life since its water dissociating property through the absorption of light energy emulates the role of chlorophyll, but unlike the latter, it is not limited to the plant cell environment. Hence, melanin is referred to as the master molecule which can provide a missing link to the biochemical processes behind the origin of life. Melanin, the Master Molecule is an exciting reference for biochemists and laymen interested in the science of melanin and a new perspective on the origin of life as we know it.

Download or read book Comprehensive Inorganic Chemistry II written by and published by Newnes. This book was released on 2013-07-23 with total page 7694 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive Inorganic Chemistry II, Nine Volume Set reviews and examines topics of relevance to today’s inorganic chemists. Covering more interdisciplinary and high impact areas, Comprehensive Inorganic Chemistry II includes biological inorganic chemistry, solid state chemistry, materials chemistry, and nanoscience. The work is designed to follow on, with a different viewpoint and format, from our 1973 work, Comprehensive Inorganic Chemistry, edited by Bailar, Emeléus, Nyholm, and Trotman-Dickenson, which has received over 2,000 citations. The new work will also complement other recent Elsevier works in this area, Comprehensive Coordination Chemistry and Comprehensive Organometallic Chemistry, to form a trio of works covering the whole of modern inorganic chemistry. Chapters are designed to provide a valuable, long-standing scientific resource for both advanced students new to an area and researchers who need further background or answers to a particular problem on the elements, their compounds, or applications. Chapters are written by teams of leading experts, under the guidance of the Volume Editors and the Editors-in-Chief. The articles are written at a level that allows undergraduate students to understand the material, while providing active researchers with a ready reference resource for information in the field. The chapters will not provide basic data on the elements, which is available from many sources (and the original work), but instead concentrate on applications of the elements and their compounds. Provides a comprehensive review which serves to put many advances in perspective and allows the reader to make connections to related fields, such as: biological inorganic chemistry, materials chemistry, solid state chemistry and nanoscience Inorganic chemistry is rapidly developing, which brings about the need for a reference resource such as this that summarise recent developments and simultaneously provide background information Forms the new definitive source for researchers interested in elements and their applications; completely replacing the highly cited first edition, which published in 1973

Book excerpt: As a spectroscopic method, nuclear magnetic resonance (NMR) has seen spectacular growth over the past two decades, both as a technique and in its applications. Today the applications of NMR span a wide range of scientific disciplines, from physics to biology to medicine. Each volume of Nuclear Magnetic Resonance comprises a combination of annual and biennial reports which together provide comprehensive coverage of the literature on this topic. This Specialist Periodical Report reflects the growing volume of published work involving NMR techniques and applications, in particular NMR of natural macromolecules which is covered in two reports: "NMR of Proteins and Nucleic Acids" and "NMR of Carbohydrates, Lipids and Membranes". For those wanting to become rapidly acquainted with specific areas of NMR, this title provides unrivalled scope of coverage. Seasoned practitioners of NMR will find this an invaluable source of current methods and applications. Volume 33 covers literature published from June 2002 to May 2003. Specialist Periodical Reports provide systematic and detailed review coverage in major areas of chemical research. Compiled by teams of leading authorities in the relevant subject areas, the series creates a unique service for the active research chemist, with regular, in-depth accounts of progress in particular fields of chemistry. Subject coverage within different volumes of a given title is similar and publication is on an annual or biennial basis.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Melanin and melanin-related materials have become novel and blooming topics for both academia and industry, due to their extraordinary functions and properties. It is found that in jaws of Glycera, melanin increases the stiffness and provides an example of organic-based particles used for reinforcement instead of inorganic materials. Although there are examples where melanin particles are added to polymers for improving mechanical performance, the mechanical properties of melanin are unknown. Here, we have probed the mechanical properties of melanin using Atomic Force Microscopy by indenting individual natural melanosome and analyzing force-displacement curves to measure the mechanical response. We found the Young's modulus obtained from at least five melanosomes for each species were 1.45±0.50 and 1.45±0.78 GPa for crow (Corvus ossifragus) and turkey (Melleagris gallopavo), respectively. The results indicate that both melanosomes have indistinguishable modulus, which are assumed to arise from the fact that they are similar in size and chemistry. Melanin is also known for protecting biological tissues from harmful UV rays. It is known that exposure to UVA results in chemical changes in melanin. Therefore, we have also used AFM to measure if the mechanical modulus is affected by UV radiation. We find that the Young's modulus for crow and turkey melanosomes after UV treatment are 1.59±0.67 and 0.97±0.53 GPa, respectively, which are statistically similar to the results without UV treatment. It was surprising that the mechanical properties were not affected by UV even though the melanosomes are degrading chemically.
