This book focuses on the biological interactions of sulfur compounds which arise specifically from the presence of the sulfur atom within the molecule. Biological Interactions of Sulfur Compounds begins with the chemistry and biology of sulfur, before introducing compounds which share a common chemical combination. Following a description of their uses and impact upon the biological field, specific chemical group characteristics are discussed, together with the biological activity and structure-activity relationships where known. The toxicity of such compounds, their consequences in biochemical and clinical terms, and their mechanisms of biological interaction are then addressed. The result is an up-to-date and informative account of the exciting area of sulfur compound biochemistry.
