This book examines the molecular biology of selenium and how this element makes its way into protein. The role of this element in preventing certain forms of cancer, heart disease and other cardiovascular and muscle disorders is explored in the text. The Second Edition outlines discoveries since the book was first introduced in 2001. Chapter updates have been written by investigators who have made important contributions to the field.
