The alkaloids were of great importance to mankind for centuries, long before they were recognized as a chemical class. The influence they have had on literature is hinted at by some of the quotations I have used as chapter headings. Their in fluence on folklore and on medicine has been even greater. The scientific study of alkaloids may be said to have begun with the isolation of morphine by SERTURNER in 1804. Since that time they have remained of great interest to chemists, and now in any month there appear dozens of publications dealing with the isolation of new alkaloids or the determination of the structures of previously known ones. The area of alkaloid biochemistry, in comparison, has received little attention, and today is much less developed. There is a certain amount of personal arbitrariness in defining "biochemistry", as there is in defining "alkaloid", and this arbitrariness is doubtless compounded by the combination. Nevertheless, it seems to me that in any consideration of the bio chemistry of a group of compounds three aspects are always worthy of attention pathways of biosynthesis, function or activity, and pathways of degradation. For the alkaloids, treatment of these three aspects is necessarily lopsided. Much has been learned about routes of biosynthesis, but information on the other aspects is very scanty. It would be possible to enter into some speculation regarding the biosyn thesis of all the more than 1,000 known alkaloids.

The use of organic corrosion inhibitors is a simple and cost-effective method for protecting processes, machinery, and materials while remaining environmentally acceptable. Organic Corrosion Inhibitors: Synthesis, Characterization, Mechanism, and Applications provides up-to-date coverage of all aspects of organic corrosion inhibitors, including their fundamental characteristics, synthesis, characterization, inhibition mechanism, and industrial applications. Divided into five sections, the text first covers the basics of corrosion and prevention, experimental and computational testing, and the differences between organic and inorganic corrosion inhibitors. The next section describes various heterocyclic and non-heterocyclic corrosion inhibitors, followed by discussion of the corrosion inhibition characteristics of carbohydrates, amino acids, and other organic green corrosion inhibitors. The final two sections examine the corrosion inhibition properties of carbon nanotubes and graphene oxide, and review the application of natural and synthetic polymers as corrosion inhibitors. Featuring contributions by leading researchers and scientists from academia and industry, this authoritative volume: Discusses the latest developments and issues in the area of corrosion inhibition, including manufacturing challenges and new industrial applications Explores the development and implementation of environmentally-friendly alternatives to traditional toxic corrosion inhibitors Covers both established and emerging classes of corrosion inhibitors as well as future research directions Describes the anticorrosive mechanisms and effects of acyclic, cyclic, natural, and synthetic corrosion inhibitors Offering an interdisciplinary approach to the subject, Organic Corrosion Inhibitors: Synthesis, Characterization, Mechanism, and Applications is essential reading for chemists, chemical engineers, researchers, industry professionals, and advanced students working in fields such as corrosion inhibitors, corrosion engineering, materials science, and applied chemistry.

Plants constantly cope with unfavourable ecosystem conditions, which often prevent them reaching their full genetic potential in terms of growth, development and productivity. This book covers plants' responses to these environmental changes, namely, the modulation of amino acids, peptides and amines to combat both biotic and abiotic stress factors. Bringing together the most recent developments, this book is an important resource for researchers and students of crop stress and plant physiology.

Amino acids are featured in course syllabuses and in project and research work over a wide spectrum of subject areas in chemistry and biology. Chemists and biochemists using amino acids have many common needs when they turn to the literature for comprehensive information. Among these common interests, analytical studies, in particular, have undergone rapid development in recent years. All other chemical and biochemical aspects of amino acids - synthesis, properties and reactions, preparation of derivatives for use in peptide synthesis, racemization and other fundamental mechanistic knowledge - have been the subject of vigorous progress. This book offers a thorough treatment of all these developing areas, and is structured in the belief that biochemists, physiologists and others will profit from access to information on topics such as the physical chemistry of amino acid solutions, as well as from thorough coverage of amino acid metabolism, biosynthesis and enzyme inhibition; and that chemists will find relevant material in biological areas as well as in the analysis, synthesis and reactions of amino acids.

Organic Chemistry Study Guide: Key Concepts, Problems, and Solutions features hundreds of problems from the companion book, Organic Chemistry, and includes solutions for every problem. Key concept summaries reinforce critical material from the primary book and enhance mastery of this complex subject. Organic chemistry is a constantly evolving field that has great relevance for all scientists, not just chemists. For chemical engineers, understanding the properties of organic molecules and how reactions occur is critically important to understanding the processes in an industrial plant. For biologists and health professionals, it is essential because nearly all of biochemistry springs from organic chemistry. Additionally, all scientists can benefit from improved critical thinking and problem-solving skills that are developed from the study of organic chemistry. Organic chemistry, like any "skill", is best learned by doing. It is difficult to learn by rote memorization, and true understanding comes only from concentrated reading, and working as many problems as possible. In fact, problem sets are the best way to ensure that concepts are not only well understood, but can also be applied to real-world problems in the work place. - Helps readers learn to categorize, analyze, and solve organic chemistry problems at all levels of difficulty - Hundreds of fully-worked practice problems, all with solutions - Key concept summaries for every chapter reinforces core content from the companion book
