Book Description
The advances in lipid biochemistry over the past 25 to 30 years have been dramatic and exciting. The elucidation of the pathways of fatty acid biosynthesis and oxidation, the delineation of the biogenesis of cholesterol from small-molecular weight precursors, the structure proof of simple and complex lipids from plants, animals, and microorganisms, are excellent examples of the spectacular advances made during the golden era of lipid biochemistry. The multifaceted discoveries in these diverse areas of study could be attributed to development of highly sophisticated column chromatographic techniques for separation and purification of simple and complex lipids. The advent of thin-layer chromatography as well as gas liquid chromatography provided an explosive impetus to research developments in this field. Concomitant advances in mass spectrometry allowed an interface with gas-liquid chromatography which spawned even greater insight into the structure of lipids. These eventful days of lipid chemistry nearly 25 years ago led to a relatively quiescent period wherein scientists applied these newly available techniques to investigation of the behavior of isolated (lipid) enzyme systems and to unraveling the intricacies of the metabolic behavior of lipids in the intact cell or whole organisms. Then, in the early 1960s, a decided change in research emphasis developed with the advent of a simple, reproducible procedure for the isolation of cell membranes.

Book Description
With the development of highly sophisticated analytical techniques and instrumentation during the past 15-20 years, progress in the field of lipid biochemistry has been greatly accelerated. Within this period, there has been an increasing volume of information concerning the distribution and metabolism of lipids in animals and, more recently, in plants. The fungi have played an important role in studies concerning the biochemistry of lipids and, in this text, they are treated separately from the photosynthetic plants. This book is concerned with distribution and bio chemistry of lipids in fungi. The text is divided into three sections, beginning with an introduction to fungallipids which includes total lipid abundances in fungal cells and cell fractions and cultural conditions influencing lipid production. In the second section, each chapter deals with the distribution andjor metabolism of a single lipid class as it occurs in fungi. Comparisons with plants and animals are also included. Six major lipid classes are covered which include the aliphatic hydrocarbons, fatty acids, sterols, triacylglycerols, glycerophosphatides, and sphingolipids. The third section contains two chapters concerned with the physiology and ultrastructure of fungal spore formation and germination with particular emphasis on lipids. Although this book is not intended to be a comprehensive review of the literature, the information presented is compiled from over 1000 articles, most of which were published during the past 10-12 years.

Book Description
Presents the State-of-the-Art in Fat Taste Transduction A bite of cheese, a few potato chips, a delectable piece of bacon – a small taste of high-fat foods often draws you back for more. But why are fatty foods so appealing? Why do we crave them? Fat Detection: Taste, Texture, and Post Ingestive Effects covers the many factors responsible for the sensory appeal of foods rich in fat. This well-researched text uses a multidisciplinary approach to shed new light on critical concerns related to dietary fat and obesity. Outlines Compelling Evidence for an Oral Fat Detection System Reflecting 15 years of psychophysical, behavioral, electrophysiological, and molecular studies, this book makes a well-supported case for an oral fat detection system. It explains how gustatory, textural, and olfactory information contribute to fat detection using carefully designed behavioral paradigms. The book also provides a detailed account of the brain regions that process the signals elicited by a fat stimulus, including flavor, aroma, and texture. This readily accessible work also discusses: The importance of dietary fats for living organisms Factors contributing to fat preference, including palatability Brain mechanisms associated with appetitive and hedonic experiences connected with food consumption Potential therapeutic targets for fat intake control Genetic components of human fat preference Neurological disorders and essential fatty acids Providing a comprehensive review of the literature from the leading scientists in the field, this volume delivers a holistic view of how the palatability and orosensory properties of dietary fat impact food intake and ultimately health. Fat Detection represents a new frontier in the study of food perception, food intake, and related health consequences.

Book Description
The hydroxamic acid reaction conditions for the determination of esterified fatty acids were modified to the extent that the variable factors involved were controlled so that the molar absorptivities per ester group for triglycerides, cholesteryl esters of long-chain fatty acids, and phosphatides were equivalent through 8 microequivalent ester. The amount of water present during the formation of hydroxamates was the most important single factor in obtaining equivalent color values with these 3 types of esters. The accuracy and precision of the method were well defined by showing that the optical density values for 5 different ester standards were on the identical straight line curve. Spectral curves between the wavelengths of 410 and 700 millimicron with standard carboxylic acid esters and Folch extracts of rat serum, rat liver, and human serum were qualitatively and quantitatively identical. A long chain cholesteryl ester must be used as one of the standard esters because of its solubility characteristics and water sensitivity. Cholesteryl acetate can not be used as a reliable representative in place of a long chain cholesteryl ester. (Author).

Book Description
Every aspect of immune function and host defense is dependent upon a proper supply and balance of nutrients. Severe malnutrition can cause significant alteration in immune response, but even subclinical deficits may be associated with an impaired immune response, and an increased risk of infection. Infectious diseases have accounted for more off-duty days during major wars than combat wounds or nonbattle injuries. Combined stressors may reduce the normal ability of soldiers to resist pathogens, increase their susceptibility to biological warfare agents, and reduce the effectiveness of vaccines intended to protect them. There is also a concern with the inappropriate use of dietary supplements. This book, one of a series, examines the impact of various types of stressors and the role of specific dietary nutrients in maintaining immune function of military personnel in the field. It reviews the impact of compromised nutrition status on immune function; the interaction of health, exercise, and stress (both physical and psychological) in immune function; and the role of nutritional supplements and newer biotechnology methods reported to enhance immune function. The first part of the book contains the committee's workshop summary and evaluation of ongoing research by Army scientists on immune status in special forces troops, responses to the Army's questions, conclusions, and recommendations. The rest of the book contains papers contributed by workshop speakers, grouped under such broad topics as an introduction to what is known about immune function, the assessment of immune function, the effect of nutrition, and the relation between the many and varied stresses encountered by military personnel and their effect on health.
