The Porphyrin Handbook

The Porphyrin Handbook, Volume 18: Multiporphyrins, Multiphthalocyanines and Arrays provides information pertinent to every aspect of the chemistry, synthesis, spectroscopy, and structure of phthalocyanines. This book examines the biology and medical implications of porphyrin systems. Organized into five chapters, this volume begins with an overview of the results obtained in the research concerning the properties and formation of a class of metal phthalocyanine derivatives containing of two macrocyclic units. This text then examines the luminescence and photophysical data of multiporphyrin systems in which the chromophore centers are held together by weak, medium, or strong bonding interactions. Other chapters consider the intensive electronic absorption and circular dichroism properties of chiral phthalocyanines. This book discusses as well the chemistry porphyrin and corrin systems. The final chapter deals with geoporphyrins or sedimentary porphyrins, which are the most abundant porphyrin derivatives on earth. This book is a valuable resource for research scientists, engineers, and clinicians.

The Porphyrin Handbook, Volume 11: Bioinorganic and Bioorganic Chemistry presents the fundamental aspects of the synthesis, structure, chemistry, and spectroscopy of phthalocyanines. This book discusses the biology and medical implications of porphyrin systems. Organized into seven chapters, this volume begins with an overview of the design, synthesis, and study of the structural and functional models of heme/copper terminal oxidases. This text then examines the proteins containing iron-protoporphyrin IX (heme), which play key roles in photosynthesis and respiration. Other chapters consider the syntheses of chiral porphyrin derivatives and summarize the uses of such compounds in enantioselective control. This book discusses as well the reactivity and synthesis of synthetic carbine metalloporphyrins. The final chapter deals with the B12-coenzymes, which is the most complex and physiologically important organometallic enzymatic reactions that directly depend on the reactivity of metal coordinated organic ligands. This book is a valuable resource for research scientists, clinicians, and engineers.

Handbook Of Porphyrin Science: With Applications To Chemistry, Physics, Materials Science, Engineering, Biology And Medicine (Volumes 31-35)

This is the seventh set of Handbook of Porphyrin Science.Porphyrins, phthalocyanines and their numerous analogue and derivatives are materials of tremendous importance in chemistry, materials science, physics, biology and medicine. They are the red color in blood (heme) and the green in leaves (chlorophyll); they are also excellent ligands that can coordinate with almost every metal in the Periodic Table. Grounded in natural systems, porphyrins are incredibly versatile and can be modified in many ways; each new modification yields derivatives, demonstrating new chemistry, physics and biology, with a vast array of medicinal and technical applications.As porphyrins are currently employed as pl...

Emissions Trading and Business

Emissions trading (ET) challenges business managers in an entirely new manner, changing the criteria by which environmental policy steers management decisions from hierarchical to monetary. The 24 contributions to this volume discuss ET theoretically and empirically in these broad topic areas: 1) Institutional design, decision making and innovation; 2) Investment and management strategies; 3) ET and business administration and 4) Effects of existing and emerging ET schemes.

Thiol-based redox homeostasis and signalling

Thiol-based redox homeostasis and signalling

In contrast to the situation in heterotrophic organisms, plant genomes code for a significantly larger number of oxidoreductases such as thioredoxins (TRXs) and glutaredoxins (GRXs). These proteins provide a biochemical mechanism that allows the rapid and reversible activation or deactivation of protein functions in response to changing environmental conditions, as oxidative conditions caused by excessive photosynthesis. Indeed, owing to the fact that cysteines are sensitive to oxidation, TRXs and GRXs play an essential role in controlling the redox state of protein thiol groups. These redox-dependent post-translational modifications have proven to be critical for many cellular functions constituting regulatory, signalling or protective mechanisms. The articles contained in this Research Topic provide timely overviews and new insights into thiol-dependent redox regulation mechanisms with a focus on TRX- and GRX-based reduction systems in plants. The different contexts discussed take into account physiological, developmental and environmental conditions.
