This book provides an up-to-date overview of the biological functions of melanins, their biotechnological production, and their industrial applications. The melanins form a group of polymeric pigments found in most organisms. These natural products are generated by the oxidation of phenolic and indolic molecules yielding melanins, which include eumelanin, pheomelanin, pyomelanin, and the allomelanins. These pigments have diverse biological functions, including photoprotection, thermoregulation, antioxidation, virulence, and metal ion sequestration. Melanins have physicochemical properties that have proven useful in the optical, electronic, material, agriculture, cosmetic, pharmaceutical, and medical industries. The chapters in this book provide an in-depth analysis of the current issues and challenges in this field. Topics covered include the properties, biogenesis, and evolution of melanosomes. The book also addresses the synthesis and industrial production of melanins by microorganisms. The metabolic pathways for the synthesis of several types of polymeric pigments in microorganisms and their role in pathogenesis are reviewed. The large-scale production and purification of melanins to provide this product for industrial applications is a formidable challenge. Two chapters present and discuss the state-of-the-art used for the generation of microbial melanin-production strains and the processes for the biotechnological synthesis and purification of these pigments. Melanins are polymers that can interact with metals, a chapter reviews this capacity in the context of technological applications, including electrochemical energy storage and metal recovery. These polymers are materials having favorable characteristics for photonic applications, including UV blocking and broadband absorption. The current advances in the application of these pigments in optically active materials are presented and discussed.

The word melanin refers to dark natural pigments produced by the oxidative degradation of tyrosine, catalyzed by tyrosinase, and polymerized into insoluble granular substance. The main function of melanin is to protect from harmful agents, primarily UV radiation, but also from oxidation, heavy metals, etc. In this volume, chapters deal with production of melanin in human oral mucosa (Liviu et al.), the regulation of melanin action (Cecile et al.), production and potential technological application of fungal melanins (Pombiero-Sponchiado et al.) and an innovative method for measuring melanin in various samples (Zdybel et al.). In conclusion, this volume presents various biological and industrial aspects of melanin production, uses and analysis.

This volume covers all aspects of melanin pigmentation, providing a concise, comprehensive picture of new knowledge gained at the frontiers of research. It draws heavily on the author's 30-year activity in the field and his continuing work with specialists of widely diverse disciplines. The core of the volume deals with the structure, physicochemical properties, and biosynthesis of the major classes of melanin pigments, including neuromelanins. Further discussions include the biology of the various types of pigment-producing cells, the structure and mode of action of tyrosinase, and the chemistry of urinary melanogens and their biomedical applications as metabolic markers of melanocyte activity, especially for the follow-up of malignant melanoma. Finally, the volume considers progress in the photobiology and photochemistry of melanins, with special emphasis on the controversial role of these pigments in skin photoprotection. Melanins and Melanogenesis is ideally suited as a basic guide for newcomers, and a handy source of specific information for practitioners in academic, medical, and industrial settings.

Human melanin is synthesized in melanosomes located in melanocytes of the skin, hair, eyes, and leptomeninges. Melanin not only determines skin color, but also protects the skin from UV damage by absorbing UV light. In this book, the authors present current research in the study of the biosynthesis, functions and health effects of melanin. Topics include melanogenesis and natural hypopigmentation agents; fungal melanins; the coat color genes that regulate eumelanin and pheomelanin synthesis in melanocytes; the role of melanin production in gaeumannomyces graminis infection of cereal plants and the occurrence and function of melanic pigmentation in ectothermic vertebrates.

Melanin is a biological molecule associated with pigmentation in humans and animals. However, melanin has been observed to have other functions such as neuroprotection and energy production. In Melanin, the Master Molecule, researchers summarize several decades worth of knowledge on melanin and its physicochemical properties. Nine chapters explain the intrinsic biochemistry of melanin, comparisons with conventional energy producing and respiratory biomolecules, the property of melanin to transform light energy into chemical energy through the dissociation of the water molecule, and the theories of melanin based energy production in the nervous system, the cell nucleus, muscles and the eye, and the role the role of melanin in the context of ageing. The authors also delve into the possibility of melanin being the key molecule needed to spark life since its water dissociating property through the absorption of light energy emulates the role of chlorophyll, but unlike the latter, it is not limited to the plant cell environment. Hence, melanin is referred to as the master molecule which can provide a missing link to the biochemical processes behind the origin of life. Melanin, the Master Molecule is an exciting reference for biochemists and laymen interested in the science of melanin and a new perspective on the origin of life as we know it.

This book is compiled of scientific research on melanin and copper as well as my personal experiences and understanding of them being one and the same. All pigment comes from copper and in that pigment we see the process of life in motion. Melanin is the name of the human pigment, but copper is the source.
