Professionals recognize entropy-enthalpy compensation as an important factor in molecular recognition, lead design, water networks, and protein engineering. It can be experimentally studied by proper combinations of diverse spectroscopic approaches with isothermal titration calorimetry and is clearly related to molecular dynamics. So, how should we treat entropy-enthalpy compensation? Is it a stubborn hindrance that solely complicates the predictability of phenomena otherwise laid on the line by Mother Nature? How should we then deal with it? This book dwells on these posers. It combines two chapters written by globally recognized specialists. Chapter 1 deals with general issues and suggests a definite approach to how we may answer the posers. Chapter 2 shows how the approach outlined might be successfully applied in a rational design of enzymes. This might provide other interesting strategic perspectives in the general theoretical physical chemistry field.

Mankind is dependent on energy from gas, oil, coal, atomic energy, and various other sources. In all fossil fuel combustion processes, carbon dioxide (CO2) is produced (ca. 25 Gt/year). In the past few decades, we have observed a constant increase in CO2 content in the air (currently ca. 400 ppm [0.04%]). This book discusses the technology related to carbon (i.e., CO2) capture and sequestration (CCS) from fossil fuel energy plants, which is considered an important means of CO2 control. It also covers the adsorption/absorption processes of CO2 on solids and similar procedures to help address growing climate change concerns.
This unique volume presents new understandings of the neurochemical nature of major depression, and how herbs and their constituent flavonoids and terpenes appear to address some of the mechanisms now thought to be involved. It explores how recent studies of the rapid antidepressant effects of ketamine inform neuroscientists about deep intracellular mechanisms of antidepressant action that have little to do with simple enhancement of monoaminergic activity. These mechanisms include actions on PI3K, Akt, mTOR, GSK3, BDNF, and other intracellular pathways. New theories of the pathophysiology underlying major depression, such as oxidative damage, inflammation, stress and insulin resistance are then explored. Key Features: Focuses on oxidative damage, inflammation, and metabolic syndrome. Explains that a significant percentage of people treated for major depression obtain little if any relief from standard antidepressant medications. These facts lead to discussion of herbs that can be used to treat major depression, as well as consideration of the scientific basis for how these herbs act. The antidepressant properties of 66 herbs are discussed, along with dosing and safety information.
Generally speaking, quantitative-structure activity relationship (QSAR) is a technique which correlates the biological activities of a set of compounds to their structures using a mathematical equation represented in its general form by Biological Activity = f (x1, ..., xn), where f is a mathematical function and x1, ..., xn are n molecular descriptors. Since the introduction of the initial concept of QSAR in the early 1960s, numerous advances have been introduced into the field transforming it into an essential tool in drug discovery and medicinal chemistry. Quantitative Structure - Activity Relationship: A Practical Approach provides a detailed overview of computational approaches in QSAR studies. It covers the applications of different algorithms in various steps of a QSAR analysis and shows clear examples. Each chapter introduces the tools and software involved.

Recent advances in science have clarified the role of plant specialized metabolites (classically known as plant secondary metabolites), which cannot be considered only bioactive molecules used for human health but also pivotal factors for the global ecosystem. They play major roles in plant life, evolution, and mutualism. To provide the reader a general view of plant specialized metabolites, it is important to consider both the biochemistry and the functional/ecological role of these important compounds. Around 200,000 specialized metabolites are formed by a wide array of plant metabolic pathways from numerous plant taxa and through learning how other species (including human beings) rely on them. Plant Specialized Metabolism: Genomics, Biochemistry, and Biological Functions will provide the reader with special insights into the sophisticated nature of these metabolites and their various and valuable uses based on the most recent findings in science. The field of plant specialized metabolism has witnessed tremendous growth in the past decade. This growth has had a profound impact on multiple disciplines in life science, including biochemistry, metabolism, enzymology, natural product chemistry, medicinal chemistry, chemical ecology, and evolution. It also has yielded valuable knowledge and technology readily applicable in various industries, such as agriculture, horticulture, energy, renewable chemicals, and pharmaceuticals. The book focuses on the molecular background of secondary metabolite biosynthesis, their functional role, and potential applications.
Phosphorus is an essential plant nutrient, but global population growth has dramatically reduced the availability of phosphorus fertilizer resources. Despite this scarcity, there remain numerous problems associated with the excessive and inappropriate use of phosphorus leading to non-point source pollution and eutrophication of natural waters. Identifying appropriate systems for managing soil phosphorus and reducing the risks of eutrophication are needed to minimize the environmental risks. This book focuses on the availability and recycling of phosphorus; regulatory and policy issues of sustainable phosphorus use; and water quality management in agroecosystems pertaining to phosphorus. Sections are dedicated to global phosphorus reserves; cycling and pathways of phosphorus; phosphorus in agriculture; human dimensions and policy intervention; and research and development priorities. Phosphorus is a finite but crucial resource and is an essential element to all life. Sub-optimal availability and nutrient imbalance in the root zone can adversely impact plant growth, and the quality of food and feed grown on these soils. However, the proven reserves of phosphorus can hardly be adequate for a few centuries only. Yet, its misuse and mismanagement has caused severe problems of eutrophication of water and pollution of the environment. Thus, judicious management of soil phosphorus is essential. This volume is specifically devoted to availability and recycling of phosphorus, regulatory/policy issues of sustainable use of phosphorus, and management in agroecosystems in the context of maximizing the use efficiency and minimizing the environmental risks of water quality.
Trace Elements in Abiotic and Biotic Environments helps readers understand the fundamental principles and phenomena that control the transfer of trace elements. This book describes the occurrence and behavior of trace elements in rocks, soil, water, air, and plants, and also discusses the anthropogenic impact to the environment. In addition, it covers the presence of trace elements in feeds, as either contaminants or as nutritional or zootechnical additives, and their transfer across the food chain to humans. Also discussed is international legislation on trace elements for both micronutrients and contaminants in soil and plant food. A special focus is placed on the human health effects of both trace element deficiency and excess. All trace elements are covered-from aluminum to zirconium-as well as rare-earth elements (actinides and lanthanides). |
