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 37 covers literature published from June 2006 to May 2007.

This is the first volume of a first-of-its-kind four-volume book set that provides readers with up-to-date information on α-amino acids, the potential challenges in working with α-amino acids, the protecting groups for the carboxyl, amino and side chain groups of the amino acids, and the most popular heterocyclic compounds that are originating from α-amino acids. These heterocyclic compounds include hydantoins, thiohydantoins (including 2-thiohydantoins, 4-thiohydantoins, 2,4-dithiohydantoins), 2,5-diketopiperazines, N-carboxyanhydrides, N-thiocarboxyanhydrides, sydnones, sydnonimines, azlactones, pseudoazlactones, and oxazolidin-5-ones. This is the first resource to comprehensively collect all the heterocycles that can be directly prepared from α-amino acids. In addition, almost all kinds of synthetic methods for a particular type of heterocycles from α-amino acids are included, along with the detailed mechanistic discussions and experimental procedures. Volume 1: Protecting Groups collects and discusses the 260 protecting groups relating to amino acids, which have been organized by carboxyl group, amino group, and side chain group. The conditions to introduce these protecting groups as well as their deprotecting procedures have also been incorporated, along with the physical properties, solvent effects, and temperature effects on the solubility of amino acids. It presents the solubility of glycine and phenylalanine in a variety of solvent systems to show the impact on amino acid, where glycine generally represents the polar amino acid whereas phenylalanine represents the amino acid of non-polar side chain. The other volumes include: Volume 2: Hydantoins, Thiohydantoins, and 2,5-Diketopiperazines Volume 3: N-Carboxyanhydrides, N-Thiocarboxyanhydrides, and Sydnones Volume 4: Azlactones and Oxazolidin-5-ones All together, this unique 4-volume set thoroughly covers the two types of heterocyclic compounds that are originated from alpha-amino acids, providing carefully compiled updated information with detailed examples. The author has shared many thoughtful insights based on his strong background in physical organic chemistry. The volumes will be highly valuable for graduate students and senior students, as well as for professors and researchers working in the field of medicinal and pharmaceutical chemistry, organic chemistry, organic synthesis, heterocycles, and proteins and peptides.

The large-scale production of chemicals to meet various societal needs has created environmental pollution, including pollution from byproducts and improper disposal of waste. With the world facing adverse consequences due to this pollution, green chemistry is increasingly being viewed as a means to address this concern. Since most organic syntheses require toxic solvents, more reaction time, and drastic conditions of temperature, conventional methods of organic synthesis are less preferred. Microwave-assisted organic synthesis is considered to be a promising green chemical approach because it reduces reaction time from days or hours to minutes or even seconds, and has many other advantages. It helps reduce side reactions and increase yields, uses fewer solvents or is almost solvent-free, has solid supported reactions, and improves purity. This book’s main focus is microwave-assisted organic synthesis processes, particularly various reactions such as cycloaddition, rearrangement, elimination, substitution, oxidation, reduction, condensation, coupling, polymerization, nanomaterials, synthesis of heterocycles, and industrial applications under microwave irradiation. The time is not far off when this methodology will virtually replace existing and cumbersome methods of organic synthesis.

A Schiff base (imine -N=CH-) is a part of a popular group of organic compounds prepared form primary amines and aldehyde. Many studies have been carried out on Schiff bases not only as organic compounds but also as ligands for metal complexes. In this context, this book provides a comprehensive, interdisciplinary review of Schiff base compounds, with an emphasis on the latest advances. It compiles research results, commentary, reviews, and more dealing with preparation, spectroscopy, crystallography, (asymmetric) synthetic roles, physical properties (magnets, optics, etc.), computational chemistry, and theoretical chemistry. The book focuses on Schiff base and its strong connection to organic chemistry, biochemistry, and polymer materials chemistry. It covers three topics: Schiff base of organic chemistry, Schiff base of inorganic chemistry, and Schiff base of functional or biological materials.

The Opuntia fruits, commonly known as cactus pears or prickly pears, have been suggested by the Food and Agriculture Organization to be a promising and strategic crop in regions suffering from lack of water. In Mexico, India, South Africa, and the Mediterranean, the Opuntia fruits have become popular due to their nutritive value and health-promoting benefits, including antioxidant, antiulcerogenic and antiatherogenic traits and protective effects against LDL oxidation. Additionally, readily absorbable sugars, high vitamin C and mineral content, and a pleasant flavour make Opuntia tailor-made for novel foods. Due to their ecological advantages, high functional value, and health-related traits, Opuntia fruits can be highly exploited in different food processing applications. For instance, Opuntia cactus fruits are used for the preparation of juices and marmalades; Opuntia cactus plants are used to feed animals in African and Latin American countries; Peruvian farmers cultivate Opuntia cactus for growing the cochineal (Dactylopius coccus) insect and producing the natural dye carmine; and the commercial production of food and non-food products from Opuntia has been established in Mexico, USA and several Mediterranean countries. Opuntia spp.: Chemistry, Bioactivity and Industrial Applications creates a multidisciplinary forum of discussion on Opuntia cactus with special emphasis on its horticulture, post-harvest, marketability, chemistry, functionality, health-promoting properties, technology and processing. The text includes detailed discussion of the impact of traditional and innovative processing on the recovery of high-added value compounds from Opuntia spp. by-products. Later chapters explore the potential applications of Opuntia spp. in food, cosmetics and pharmaceutical products.
