This survey was written at the invitation of the Editors of the "Ergebnisse der Physiologie". Its aim is to present the more recent progress in the know ledge of biological energy transformations. Since it was intended for a review journal, the reader was taken to be familiar with the fundamentals of current biochemistry, as described in the standard textbooks. It was not the object to compile an extensive collection of facts. The survey is limited to aspects of wider interest, and the main emphasis has been on the general unifying principles which emerge from the great mass of detailed ob servations. The article is reprinted in the hope that it may be useful in this form to advanced students and research workers in biochemistry and related subjects. H. A. KREBS H. L.

Metabolic Pathways, Third Edition: Volume IV: Nucleic Acids, Protein Synthesis, and Coenzymes focuses on the metabolic pathways of the major biological constituents of living organisms, namely, nucleic acids, proteins, and coenzymes. The biosynthesis and metabolism of purines and pyrimidines, nucleotides, riboflavin and related compounds, and vitamin B6 are discussed. The biogenesis and metabolism of thiamine and folic acid are also considered. This volume is comprised of seven chapters and begins with an analysis of metabolic control and enzymology of purines and pyrimidines such as inosinic acid and nucleotides. The next chapter is devoted to the biosynthesis and metabolism of nucleotides and nucleic acids, making reference to deoxyribonucleotides as well as RNA and DNA. Some of the reactions involving nucleotides are classified and briefly discussed. The reader is then introduced to protein synthesis, paying particular attention to the chemical features of the synthesis of the peptide bond and the characteristics of the genetic code implicated in this process. The remaining chapters focus on riboflavin and related compounds, thiamine, folic acid, and vitamin B6. This book will be a useful resource for biochemists and biologists.

Principles of Bioenergetics summarizes one of the quickly growing branches of modern biochemistry. Bioenergetics concerns energy transductions occurring in living systems and this book pays special attention to molecular mechanisms of these processes. The main subject of the book is the "energy coupling membrane" which refers to inner membranes of intracellular organelles, for example, mitochondria and chloroplasts. Cellular cytoplasmic membranes where respiratory and photosynthetic energy transducers, as well as ion-transporting ATP-synthases (ATPases) are also part of this membrane. Significant attention is paid to the alternative function of mitochondria as generators of reactive oxygen species (ROS) that mediate programmed death of cells (apoptosis and necrosis) and organisms (phenoptosis). The latter process is considered as a key mechanism of aging which may be suppressed by mitochondria-targeted antioxidants.

Emphasizing the physical and technological aspects of plant energetics, this comprehensive book covers a significant interdisciplinary research area for a broad range of investigators. Plant Energetics presentsthe thermodynamics of energy processes in plants, their interconnection and arrangement, and the estimation of intrinsic energy needs of the plant connected with performing various physiological functions. The book also demonstrates the role of electrical and electrochemical processes in the plants life cycle. Plant Energetics incorporates such diverse themes as thermodynamics, biophysics, and bioelectrochemistry with applications in horticulture and ecology. It also discusses the roles and mechanisms of both quantum and thermophysical processes of theconversion of solar energy by plants, including photosynthesis and long distance transport. Comprehensive details of value to basic and applied researchers dealing with photosynthesis, agriculture, horticulture, bioenergetics, biophysics, photobiology, and plant physiology make Plant Energetics an informative, one-stop resource that willsave time and energy in your search for the latest information. - Plant Energetics incorporates such diverse themes as thermodynamics, biophysics, and bioelectrochemistry with applications in horticulture and ecology.
