The lipases and phospholipases represent a diverse group of enzymes that are expressed in animals, plants, fungi, and bacteria. Their ubiquitous distribution among all species is a testament to the essential roles played by these enzymes in lipid storage, mobilization and metabolism, membrane homeostasis and remodeling, endocrine and immune functions, and signal tra- duction. In humans, lipases and phospholipases are also thought to contribute to complex diseases, such as atherosclerosis, obesity, arthritis, and cancer, as well as to single gene defects, such as Wolman's disease and Type I hyperlipoproteinemia. Enzymatically, the lipases are unique, since they hydrolyze substrates that are either insoluble, or only partly soluble, in aq- ous solvents; thus, enzyme catalysis takes place at a lipid-water interface. The interface comprises at least two, and often more, discrete bulk and s- face phases, in which the enzyme, substrate, and products oflipolysis disperse among these phases based on their physical properties. Furthermore, the d- tribution of these components changes continuously as lipolysis proceeds. Thus, the lipases and phospholipases are fundamentally different from any other enzyme because of the physical complexity of the environment in which catalysis occurs.

A collection of papers that comprehensively describe the major areas of research on lipid metabolism of plants. State-of-the-art knowledge about research on fatty acid and glycerolipid biosynthesis, isoprenoid metabolism, membrane structure and organization, lipid oxidation and degradation, lipids as intracellular and extracellular messengers, lipids and environment, oil seeds and gene technology is reviewed. The different topics covered show that modern tools of plant cellular and molecular biology, as well as molecular genetics, have been recently used to characterize several key enzymes of plant lipid metabolism (in particular, desaturases, thioesterases, fatty acid synthetase) and to isolate corresponding cDNAs and genomic clones, allowing the use of genetic engineering methods to modify the composition of membranes or storage lipids. These findings open fascinating perspectives, both for establishing the roles of lipids in membrane function and intracellular signalling and for adapting the composition of seed oil to the industrial needs. This book will be a good reference source for research scientists, advanced students and industrialists wishing to follow the considerable progress made in recent years on plant lipid metabolism and to envision the new opportunities offered by genetic engineering for the development of novel oil seeds.

“Infogest” (Improving Health Properties of Food by Sharing our Knowledge on the Digestive Process) is an EU COST action/network in the domain of Food and Agriculture that will last for 4 years from April 4, 2011. Infogest aims at building an open international network of institutes undertaking multidisciplinary basic research on food digestion gathering scientists from different origins (food scientists, gut physiologists, nutritionists...). The network gathers 70 partners from academia, corresponding to a total of 29 countries. The three main scientific goals are: Identify the beneficial food components released in the gut during digestion; Support the effect of beneficial food components on human health; Promote harmonization of currently used digestion models Infogest meetings highlighted the need for a publication that would provide researchers with an insight into the advantages and disadvantages associated with the use of respective in vitro and ex vivo assays to evaluate the effects of foods and food bioactives on health. Such assays are particularly important in situations where a large number of foods/bioactives need to be screened rapidly and in a cost effective manner in order to ultimately identify lead foods/bioactives that can be the subject of in vivo assays. The book is an asset to researchers wishing to study the health benefits of their foods and food bioactives of interest and highlights which in vitro/ex vivo assays are of greatest relevance to their goals, what sort of outputs/data can be generated and, as noted above, highlight the strengths and weaknesses of the various assays. It is also an important resource for undergraduate students in the ‘food and health’ arena.

This book was stimulated by the enthusiasm shown by attendees at the meetings in Saxon River, VT, sponsored by the Federation ofAmerican Societies for Experimental Biology (FASEB), on the subject of the intestinal processing of lipids. When these meetings were first started in 1990, the original organizers, two of whom are editors ofthis volume (CMM and PT), had two major goals. The first was to bring together a diverse group ofinvestiga tors who had the common goal of gaining a better understanding of how the intestine ab sorbs lipids. The second was to stimulate the interest of younger individuals whom we wished to recruit into what we believed was an exciting and fruitful area ofresearch. Since that time, the field has opened up considerably with new questions being asked and new an swers obtained, suggesting that our original goals for the meetings were being met. In the same spirit, it occurred to us that there has not been a recentbook that draws to gethermuch ofthe informationavailableconcerninghow the intestineprocesses lipids. This book is intended to reach investigators with an interest in this area and their pre- and post doctoral students. The chapters are written by individuals who have a long-term interest in the areas about which they write, and many have been speakers at the subsequent FASEB conferences that have followed on the first.

Lipases and Phospholipases are key control elements in mammalian metabolism. They share many common features that set them apart from other metabolic enzyme classes, most importantly their association with biological membranes. Their potential as drug targets for the treatment of metabolic diseases is widely recognized, and the first lipase inhibitor drugs have been successfully introduced. Providing drug developers with a firm foundation for lipase-centered drug design, the editors of this volume have assembled experts from different scientific disciplines to create a comprehensive handbook for all pharmaceutical chemists, biochemists and physiologists working with lipases. The authors examine fundamental aspects of lipase function in vitro and in vivo, explaining how this knowledge may be used to develop lipase assays. They also treat the physiological roles of lipases in normal and disordered metabolism, as well as strategies to target lipases for the treatment of diabetes, obesity and related disorders. Additional topics include the application of phospholipases for liposome-based drug delivery and their use as diagnostic tools.
