Book excerpt: Biochemistry of Vision provides information pertinent to vision biochemistry. This book discusses the biochemical information derived primarily from studies on nonocular tissues and describes the biochemical reactions related to the function of the retina and pigmented epithelium. Organized into 16 chapters, this book begins with an overview of the visual system and the structure of the vertebrate eye. The text then proceeds with a discussion of photoreceptor, which has a highly membranous structure. Other chapters cover a brief discussion of several topics, including biomembranes, photochemistry, spectral properties of retinal isomers, and the photochemical properties of the chromophore of rhodopsin. This book discusses as well the properties and intramembrane disposition of rhodopsin. The final chapter deals with the biochemistry of photoreceptor disorders and summarizes the basic knowledge on neurotransmitters and electrophysiology in the retina. This book is intended for ophthalmologists and medical students who are interested in the molecular aspects of photoreceptor diseases.

Available in PDF, EPUB and Kindle. Book excerpt: My first introduction to the eye came more than three decades ago when my close friend and mentor, the late Professor Isaac C. Michaelson, convinced me that studying the biochemistry of ocular tissues would be a rewarding pursuit. I hastened to explain that I knew nothing about the subject, since relatively few basic biochemical studies on ocular tissues had appeared in the world literature. Professor Michaelson assured me, however, that two books on eye biochemistry had already been written. One of them, a beautiful monograph by Arlington Krause ( 1934) of Johns Hopkins Hospital, is we II worth reading even today for its historical perspective. The other, published 22 years later, was written by Antoinette Pirie and Ruth van Heyningen ( 1956), whose pioneering achievements in eye biochemistry at the Nuffield Laboratory of Ophthalmology in Oxford, England are known throughout the eye research community and beyond. To their credit are classical investigations on retinal, corneal, and lens biochemistry, beginning in the 1940s and continuing for many decades thereafter. Their important book written in 1956 on the Biochemistry of the Eye is a volume that stood out as a landmark in this field for many years. In recent years, however, a spectacular amount of new information has been gener ated in ocular biochemistry. Moreover, there is increasing specialization among investiga tors in either a specific field of biochemistry or a particular ocular tissue.

The diversity of visual systems in various animals is studied in zoology and comparative biochemistry.
Download or read book Photoreceptors written by Alan Fein and published by CUP Archive. This book was released on 1982-08-31 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mechanism by which photoreceptor cells in the eyes of higher animals absorb light, giving rise to receptor potentials that initiate the visual process, is a subject of active research in biophysics today. The pace of this research and its multidisciplinary nature have made it difficult for the nonexpert to keep abreast of new discoveries. This book aims to provide a more coherent, compact summary of our knowledge about the field that has been available, serving as an up-to-date introduction to the role of photoreceptors in vision. The book is a self-contained, concise handbook for the reader who has at least a college level knowledge if cell biology, biochemistry, physical chemistry, neurobiology and physics. The authors describe the physical parameters of light and proceed to describe the mechanisms by which photoreceptors extract information about each parameter. The discussion of mechanisms is organized by discipline, following the general sequence of cellular morphology, visual pigment chemistery, and receptor physiology. Photoreceptors: their role in vision is an integrated sourcebook which will serve the novice as a 'stepping stone' to the vast and exciting scientific literature of the field.
Download or read book Molecular Mechanisms in Visual Transduction written by D.G. Stavenga and published by Elsevier. This book was released on 2000-11-30 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular mechanisms in visual transduction is presently one of the most intensely studied areas in the field of signal transduction research in biological cells. Because the sense of vision plays a primary role in animal biology, and thus has been subject to long evolutionary development, the molecular and cellular mechanisms underlying vision have a high degree of sensitivity and versatility. The aims of visual transduction research are firstto determine which molecules participate, and then to understand how they act in concert to produce the exquisite electrical responses of the photoreceptor cells.Since the 1940s [1] we have known that rod vision begins with the capture of a quantum of energy, a photon, by a visual pigment molecule, rhodopsin. As the function of photon absorption is to convert the visual pigment molecule into a G-protein activating state, the structural details of the visual pigments must beexplained from the perspective of their role in activating their specific G-proteins. Thus, Chapters 1-3 of this Handbook extensively cover the physico-chemical molecular characteristics of the vertebrate rhodopsins. Following photoconversion and G-protein activation, the phototransduction cascade leads to modifications of the population of closed and open ion channels in the photoreceptor plasma membrane, and thereby to the electrical response. The nature of the channels of vertebrate photoreceptors is examined in Chapter 4, and Chapter 5 integrates the present body of knowledge of the activation steps in the cascade into a quantitative framework. Once the phototransduction cascade is activated, it must be subsequently silenced. The various molecular mechanisms participating in inactivation aretreated in Chapters 1-4 and especially Chapter 5. Molecular biology is now an indispensable tool in signal transduction studies. Numerous vertebrate (Chapter 6) and invertebrate (Chapter 7) visual pigments have been characterized and cloned. The genetics and evolutionary aspects of this great subfamily of G-protein activating receptors are intriguing as they present a natural probe for the intimate relationship between structure and function of the visual pigments. Understanding the spectral characteristics from the molecular composition can be expected to
Download or read book Biochemistry and Physiology of Visual Pigments written by Helmut Langer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a report of a four-day Symposium on the Biochemistry and Physiology of Visual Pigments, which took place immediately after the VIth International Congress on Photobiology, held in Bochum, Federal Republic of Germany, in August 1972. This meeting, which brought together about 50 investigators of various aspects of the visual process, was devoted to the visual cells of both vertebrates and invertebrates. Whereas the International Symposium on the Biochemistry of the Retina, held at Nij megen, The Netherlands, in 1968, had concentrated on vertebrate photoreceptors, this Symposium dealt with invertebrate photoreceptors as well, so that workers in each field could become acquainted with recent progress in the other area. The papers presented at the Symposium were divided into six main topics, to each of which a half-day session was devoted. The six parts of this book, following the intro ductory lecture, essentially correspond to these sessions. In addition to the invited con tributions, the volume contains a number of short communications by other partici pants and two contributions by invited participants, who were unable to attend. The volume closes, as did the Symposium, with a General Discussion, prepared and moderated by S. L. BONTING, in which an attempt was made to integrate various new findings, and to reconcile certain points of disagreement.

Download or read book Evolution of Visual and Non visual Pigments written by David M. Hunt and published by Springer. This book was released on 2014-10-04 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photopigments are molecules that react to light and mediate a number of processes and behaviours in animals. Visual pigments housed within the photoreceptors of the eye, such as the rods and cones in vertebrates are the best known, however, visual pigments are increasingly being found in other tissues, including other retinal cells, the skin and the brain. Other closely related molecules from the G protein family, such as melanopsin mediate light driven processes including circadian rhythmicity and pupil constriction. This Volume examines the enormous diversity of visual pigments and traces the evolution of these G protein coupled receptors in both invertebrates and vertebrates in the context of the visual and non-visual demands dictated by a species’ ecological niche.
