Book Description
This well-known and highly successful book was first published in 1973 and has been completely re-written in subsequent editions (published in 1982 and 2003). This new Fourth Edition has become necessary because of the pace of developments in mass spectrometry of intact lipids, which has given recognition of lipid analysis and ‘lipidomics’ as a distinct science. To bring the book up to date with these developments, author William W. Christie is joined by co-author Xianlin Han. Although devoting considerable space to mass spectrometry and lipidomics, Lipid analysis remains a practical guide, in one volume, to the complexities of the analysis of lipids. As in past editions, it is designed to act as a primary source, of value at the laboratory bench rather than residing on a library shelf. Lipid analysis deals with the isolation, separation, identification and structural analysis of glycerolipids, including triacylglycerols, phospholipids, sphingolipids, and the various hydrolysis products of these. The chapters follow a logical sequence from the extraction of lipids to the isolation and characterization of particular lipid classes and of molecular species of each, and to the mass spectrometric analysis of lipids and lipidomics. The new influence of mass spectrometry is due mainly to the development of electrospray ionization (ESI) and matrix-assisted laser desorption/ionization (MALDI). Most emphasis in this book is placed on ESI, which is enabling structural characterization of different lipid classes and the identification of novel lipids and their molecular species.

Book Description
Ever since the publication of Ancel Keys’ watershed ‘Seven Countries Study’ in 1970, medical thinking has posited a causal link between the intake of animal fats and coronary heart disease. The research of Prof. Harumi Okuyama and his colleagues presented in this new publication suggests that this link is in fact tenuous. It goes beyond that to suggest that current medical wisdom regarding lipid nutrition may actually be counterproductive. This ground-breaking analysis is likely to be debated for many years to come. The ‘Seven Countries Study’, which identified the specifics of the Mediterranean Diet and awarded it a central position in combating coronary heart disease, triggered significant changes in Western diets. Most notably, it stimulated a widespread attempt to reduce animal fats and replace them with vegetable fats. The low-density lipoprotein (LDL) element of the cholesterol naturally present in animal-source foods was dubbed a killer, and a significant industry developed around the provision of plant-based oils and fats. The clinical consensus on cholesterol was further strengthened in 1987 by the introduction of statins, an innovative class of drugs that reduce LDL production in the liver and are designed to help guard against coronary heart disease. Thirteen Nobel Prizes have been awarded to scientists who devoted major parts of their careers to cholesterol research. It is therefore a brave research team that dares to challenge the link between animal fats and coronary heart disease. This, however, is precisely what Prof. Okuyama and his team set out to do in this book. They actually recommend increasing the intake of cholesterol and animal fats, to an extent that does not lead to obesity. This recommendation is based on the discovery by Prof. Okuyama and his team that common vegetable oils such as canola and hydrogenated vegetable fats have toxic effects. They demonstrate that hydrogenated vegetable fats and oils are important culprits in atherosclerosis and other lifestyle diseases, and suggest that high total or LDL-cholesterol is not the cause of atherosclerosis or cardiovascular disease. Further, they argue that current medical guidelines on lipid nutrition conflict with evidence-based research, and that persistently focusing on LDL-cholesterol as the cause of atherosclerotic cardiovascular disease (ASCVD) is counterproductive. Key findings Some types of vegetable fats and oils exhibit stroke-inducing and endocrine-disrupting activity. Their inhibition of the vitamin K2–osteocalcin link is the major cause of ASCVD and related diseases. In the current food environment, the balance of omega-6 and omega-3 fatty acids is too much in favour of omega-6, and therefore lowering the omega-6/omega-3 ratio is recommended for the prevention of allergic and inflammatory diseases including ASCVD and cancer. Atherogenesis can develop without elevated LDL-cholesterol levels and/or in association with decreasing LDL-cholesterol levels. Increased intake of vegetable fats and oils with stroke-inducing and endocrine-disrupting activities in countries with restricted intakes of animal fats and cholesterol has led to the critical situations surrounding physical and mental health currently seen in Japan, East Asia, and the Mediterranean countries. Medical care professionals continue to insist on actively reducing LDL-cholesterol levels. This approach will only heighten the extensive health problems that Japan and some countries are at present facing. Many aspects of current medical practice in Japan are indeed likely to be in conflict with that country’s Medical Care Act. This thought-provoking analysis of one of the major health syndromes of our day demands serious consideration by professionals interested in cardiovascular health in particular and in public health more widely. Its implications are far-reaching – for medical practitioners, medical insurers, nutritionists, food producers and pharmaceutical manufacturers alike, as well as for individual patients.

Book Description
This book serves as a reference for those interested in state-of-the-art research on the science and technology of ionic liquids (ILs), particularly in relation to lipids processing and analysis. Topics include a review of the chemistry and physics of ILs as well as a quantitative understanding of structure-activity relationships at the molecular level. Further, chapter authors examine the molecular basis of the toxicity of ILs, the prediction of the properties of ILs, and the rationale and steps toward a priori design of ionic liquids for task-defined applications. Emerging research in developing lipid-inspired ILs and their prospective use in drug formulation is described. Among the highlights are the latest advances in IL-mediated biocatalysis and biotransformation, along with lipase production, purification, and activation. - Reviews the state-of-the-art applications of ionic liquids in lipid processing and relevant areas from a variety of perspectives - Summarizes the latest advances in the measurement of the physical and chemical properties of ionic liquids and available databases of thermodynamic property datapoints - Presents the tremendous opportunities provided and challenges faced from ionic liquids as a newly emerging technology for lipids processing area
