Abstract

The book largely reflect the structural diversity of echinoderm metabolites including triterpene glycosides and fucosylated chondroitin sulfates, as well as branched fatty acids, di- and triacylglycerols and other lipid classes from the sea cucumbers, polyhydroxysteroids from starfish and different classes of sphingolipids from sea cucumbers and starfish. Finally, the MS-based metabolomic approach, which is very helpful for the estimation of such diversity, is discussed. The materials from the Special Issue also illustrate the biomedical potential of the presented metabolites as cytotoxins and anticoagulants. The in silico approach broadens the possibilities to investigate the mechanisms of the action of membranolytic compounds.

Abstract

This book presents the latest knowledge and the most recent research results in the field of ganglioside biochemistry. The early chapters cover all relevant background on sialic acids and their biosynthesis, on N-glycolylneuraminic acid (Neu5Gc), which cannot be synthesized by humans, and on general aspects of ganglioside research. Ganglioside adsorption, disorders of ganglioside degradation, and the regulation of gangliosides are thoroughly discussed. A major focus of the book is the role of gangliosides in cancer. Here, the discussion encompasses, for example, the biological importance, antigenicity, and immunological actions of tumor-associated gangliosides (TAGs), the significance of different glycolipids and gangliosides as TAGs, and emerging anti-cancer vaccine strategies. The ability of sialic acids and TAGs of tumor cells to escape immunosurveillance and immunoediting also receives detailed attention. The significance of sialic acids in regulation of the complement system is explained, and the closing chapter focuses especially on the role of sialyl T antigen in cancer. The book will be of value for all who are interested in functional glycobiology and glycomic studies.

Abstract

Dairy foods make up an important part of the diets of billions of people across the globe. The nutrient composition of dairy foods adds significantly to a healthy diet, as dairy foods are an excellent or very good source of calcium, high quality protein, potassium, and riboflavin. On the other hand, some research has related dairy intake to the occurrence of certain chronic diseases. The science behind the health properties of dairy foods continue to evolve. This monograph presents current research aimed and understanding the health benefits and risks from the consumption of dairy foods.

Abstract

Although sphingolipids are ubiquitous components of cellular membranes, their abundance in cells is generally lower than glycerolipids or cholesterol, representing less than 20% of total lipid mass. Following their discovery in the brain—which contains the largest amounts of sphingolipids in the body—and first description in 1884 by J.L.W. Thudichum, sphingolipids have been overlooked for almost a century, perhaps due to their complexity and enigmatic nature. When sphingolipidoses were discovered, a series of inherited diseases caused by enzyme mutations involved in sphingolipid degradation returned to the limelight. The essential breakthrough came decades later, in the 1990s, with the discovery that sphingolipids were not just structural elements of cellular membranes but intra- and extracellular signaling molecules. It turned out that their lipid backbones, including ceramide and sphingosine-1-phosphate, had selective physiological functions. Thus, sphingolipids emerged as essential players in several pathologies including cancer, diabetes, neurodegenerative disorders, and autoimmune diseases. The present volume reflects upon the unexpectedly eclectic functions of sphingolipids in health, disease, and therapy. This fascinating lipid class will continue to be the subject of up-and-coming future discoveries, especially with regard to new therapeutic strategies.
