| define pigment in biology: Encyclopedia of Astrobiology Ricardo Amils, Muriel Gargaud, José Cernicharo Quintanilla, Henderson James Cleaves, William M. Irvine, Daniele Pinti, Michel Viso, 2021-01-14 The interdisciplinary field of Astrobiology constitutes a joint arena where provocative discoveries are coalescing concerning, e.g. the prevalence of exoplanets, the diversity and hardiness of life, and its increasingly likely chances for its emergence. Biologists, astrophysicists, biochemists, geoscientists and space scientists share this exciting mission of revealing the origin and commonality of life in the Universe. The members of the different disciplines are used to their own terminology and technical language. In the interdisciplinary environment many terms either have redundant meanings or are completely unfamiliar to members of other disciplines. The Encyclopedia of Astrobiology serves as the key to a common understanding. Each new or experienced researcher and graduate student in adjacent fields of astrobiology will appreciate this reference work in the quest to understand the big picture. The carefully selected group of active researchers contributing to this work and the expert field editors intend for their contributions, from an internationally comprehensive perspective, to accelerate the interdisciplinary advance of astrobiology. |
| define pigment in biology: Plant Pigments Trevor Walworth Goodwin, 1988 The biochemistry of plant pigments attracts continuing interest and research from a wide range of pure and applied biochemists and plant scientists. In many areas the first two editions of Professor Goodwin's Chemistry and Biochemistry of Plant Pigments have been overtaken by research and the need for a new, up-to-date summary has become pressing. This new book was conceived in response to this need. The burgeoning literature mitigates against a comprehensive treatment. Instead Professor Goodwin has identified seven topics which represent growing points in plant pigment research and has invited experts to prepare critical reviews of recent developments in them. The resulting book is an essential companion to the earlier volumes and will ensure that workers in this field are absolutely up to date with the latest thinking. |

| define pigment in biology: The Human Photosynthesis Arturo Herrera, 2017-07-09 The concept of Photosynthesis (building-up something using the Energy of light) is presently applied only to the plants kingdom. However the unraveling of the intrinsic property of melanin to split and re-form the water molecule breaks the paradigm. During a study about the three main causes of blindness initiated in 1990 in Aguascalientes, Mexico; Dr. Solis Herrera found the previously unknown capacity of melanin molecule to absorb photonic energy, dissipating it in a unique manner: splitting the water molecule. The very first step of life in plants and humans is practically the same: the dissociation of the water molecule. |

| define pigment in biology: Dyes and Pigments Ahmet Gürses, Metin Açıkyıldız, Kübra Güneş, M. Sadi Gürses, 2016-05-04 In this book the authors go back to basics to describe the structural differences between dyes and pigments, their mechanisms of action, properties and applications. They set the scene by explaining the reasons behind these differences and show how dyes are predominately organic compounds that dissolve or react with substrates, whereas pigments are (predominantly) finely ground inorganic substances that are insoluble and therefore have a different mode of coloring. They also describe the role of functional groups and their effect on dyeing ability, contrasting this with the way in which pigments cause surface reflection (or light absorption) depending on their chemical and crystalline structure and relative particle size. The book explores the environmental impact of dyes in a section that covers the physical, chemical, toxicological, and ecological properties of dyes and how these are used to assess their effect on the environment and to estimate whether a given product presents a potential hazard. Lastly, it assesses how, in addition to their traditional uses in the textile, leather, paper, paint and varnish industries, dyes and pigments are indispensable in other fields such as microelectronics, medical diagnostics, and in information recording techniques. |

| define pigment in biology: Cell Organelles Reinhold G. Herrmann, 2012-12-06 The compartmentation of genetic information is a fundamental feature of the eukaryotic cell. The metabolic capacity of a eukaryotic (plant) cell and the steps leading to it are overwhelmingly an endeavour of a joint genetic cooperation between nucleus/cytosol, plastids, and mitochondria. Alter ation of the genetic material in anyone of these compartments or exchange of organelles between species can seriously affect harmoniously balanced growth of an organism. Although the biological significance of this genetic design has been vividly evident since the discovery of non-Mendelian inheritance by Baur and Correns at the beginning of this century, and became indisputable in principle after Renner's work on interspecific nuclear/plastid hybrids (summarized in his classical article in 1934), studies on the genetics of organelles have long suffered from the lack of respectabil ity. Non-Mendelian inheritance was considered a research sideline~ifnot a freak~by most geneticists, which becomes evident when one consults common textbooks. For instance, these have usually impeccable accounts of photosynthetic and respiratory energy conversion in chloroplasts and mitochondria, of metabolism and global circulation of the biological key elements C, N, and S, as well as of the organization, maintenance, and function of nuclear genetic information. In contrast, the heredity and molecular biology of organelles are generally treated as an adjunct, and neither goes as far as to describe the impact of the integrated genetic system. |
