Mitochondria

About this book

This book is the eagerly awaited second edition of the best-selling Mitochondria, a book widely acknowledged as the first modern, truly comprehensive authored work on the important, scientifically fundamental topic of the cellular organelles known as mitochondria.

This new edition brings readers completely up to date on the many significant findings that have occurred in the eight years since the book was first published. As in that seminal first edition, the second edition tackles the biochemistry, genetics, and pathology of mitochondria in different organisms. The new edition provides thorough updates of all literature concerning this vital organelle, its functions, ongoing research surrounding it, and its importance vis-#-vis a broad range of issues in cellular and molecular biology. The book includes detailed descriptions of current and developing technologies around mitochondrial research and discovery, and highlights subjects that are growing, such as the use of proteomics.
