This volume contains eight chapters that present both new and reviewed information fundamental to a clear understanding of lipid catabolism and transport at the molecular level. Abstract: In circulation human serum albumin (HSA) is the principal carrier for endogenous lipophilic compounds, primarily non-esterified long chain fatty acids (FA). This book is comprised of 17 chapters and begins with a commentary on how albumin is used, misused, and abused in the treatment of disease such as peptic ulcer, and a description of the real indications for its use. The first of its kind, All About Albumin summarizes the chemistry, genetics, metabolism, clinical implications, and commercial aspects of albumin. This book provides an overview of the expanding field of preclinical and clinical applications and developments that use albumin as a carrier of drug delivery systems. Found insideThe present book contains the Proceedings of a two day Symposium on Uremic Toxins organized at the University of Ghent in Belgium.
