The Protein Folding Problem

The Protein Folding Problem

Proteins in living systems carry out a great variety of specific functions each of which depends on the precise three-dimensional structure of a particular protein. Proteins are synthesized in the form of a flexible polypeptide chain that is capable of assuming a vast number of configurations; the transformation of this chain into a specific relatively rigid three-dimensional structure is called folding-a remarkable process of self-organization. It is known that the amino acid sequences of some proteins have sufficient information to determine their three-dimensional structures. There are other proteins whose folding requires additional information beyond that found in the sequence of the mature protein. This book introduces the central problem of folding mechanisms as well as a number of other closely related issues. This book is neither a textbook nor a treatise. Rather it is an attempt by several investigators to convey the excitement and challenges of those aspects of the folding problem in which they are actively engaged. The contributors give brief introductions to protein folding from the perspectives of molecular architecture stability and dynamics phage genetics DNA exons general physiology and natural selection. They point out emerging new directions including the suggestion of a class of diseases that result from protein folding defects. | The Protein Folding Problem

Protein Calories And Development Nutritional Variables In The Economics Of Developing Countries

Protein Calories And Development Nutritional Variables In The Economics Of Developing Countries

Production of world food supplies is related to more complicated socioeconomic variables than have previously been analyzed. Besides traditional inputs of land labor and fertilizer the technological capabilities and a variety of nutritional and other human capital components are significant independent variables in explaining agricultural production in the developing world. The integration of economic analyses with the concepts of nutritional science offers an expanded and effective means for analyzing the complex problems of agricultural production in nutritionally deficient countries. Bernard Schmitt traces the circular relationship between nutrition and human capital labor productivity food production and per capita consumption of calories and protein. He defines the basic nutritional terms that are most useful to economists in analyzing agricultural and foodrelated questions and provides examples that stress the importance of concentrating on nutritional quality as well as gross quantity. Transformations are used to convert quantities into basic nutritional components allowing more meaningful quantitative analyses in an econometric framework. Dr. Schmitt presents a flexible methodology for forecasting commodity production using it to make projections for the developing countries for each major commodity group and to test various policy alternatives such as extensive trade expanded food assistance programs substantial resource or input expansion further expansion of Green Revolution technology and development of alternatives to agriculture. Although he is certain that gains can be accomplished through population control and agricultural advances supplemented by alternative nutritional sources he concludes that conditions in nutritionally deficient countries are unlikely to improve on average through the mid-1980s. | Protein Calories And Development Nutritional Variables In The Economics Of Developing Countries

Abnormal Hemoglobins in Human Populations

Abnormal Hemoglobins in Human Populations

Research on abnormal human hemoglobins (protein in blood that carries oxygen) has taught us about the inheritance biochemistry and distribution of these traits. This knowledge coupled with mathematical research using computer models of population genetics has enabled researchers to marry biological fact and genetic theory. This volume places medical understanding in an evolutionary framework. Using published data on the frequencies of abnormal hemoglobins in the world's populations Livingston analyzes and interprets these frequencies in the light of world distribution of different forms of diseases such as malaria. He further develops the genetic theory of the evolutionary homeostasis. Livingston discusses the relation of abnormal hemoglobins to endemic malaria and shows how natural selection pressures explain the known distribution of these traits. Where non-coinciding distributions arise the book presents other genetic anthropological evolutionary and epidemiological evidence to explain these discrepancies. This classic work remains a useful sourcebook for professors and graduate students of anthropology genetics epidemiology and hematology. | Abnormal Hemoglobins in Human Populations

Foundations of Naturopathic Nutrition A comprehensive guide to essential nutrients and nutritional bioactives

Foundations of Naturopathic Nutrition A comprehensive guide to essential nutrients and nutritional bioactives

Nutrition is a vital part of the complementary approach to health. This uniquely comprehensive and evidence-based text provides a detailed and systematic guide to the principles of clinical nutrition from a naturopathic perspective. The text begins with an overview of basic physiological principles and the body's protective systems such as the antioxidant detoxification and immune systems. The focus then moves to an in-depth examination of food components including essential nutrients such as protein lipids carbohydrates vitamins minerals and trace elements as well as nutritional bioactives such as coenzyme Q10 alpha-lipoic acid phytochemicals digestive enzymes and probiotics. There is detailed information on how each food component is digested and metabolised in the body and guidance on its impact on health including an explanation of the effects of inadequate and excessive intake. The types of supplements available together with dietary sources are also explored. Discussions of important nutritional topics are featured - for example water as therapy obesity anorexia nervosa high-protein diets hypoglycaemia diabetes phytosterols gamma-tocopherol vitamin E and mortality vitamin C and cancer infantile scurvy acid-forming and alkaline-forming diets hair analysis sodium and blood pressure and coenzyme Q10 and cancer. Summary boxes case studies and quizzes will help readers consolidate their knowledge. Foundations of Naturopathic Nutrition is an essential reference for everyone studying nutrition from a complementary health perspective. 'I thoroughly recommend this book as a learning aid for students and as an excellent reference guide for experienced practitioners. ' - Jackie Day President Naturopathic Nutrition Association (UK)'A fabulous resource not only for practitioners but also all those with an interest in nutrition. ' - Professor Alan Bensoussan Director National Institute of Complementary Medicine University of Western Sydney'The foundation nutrition text we've all been waiting for. Fay Paxton has drawn from her many years of clinical nutrition experience combining it with relevant research-based evidence to produce an exhaustive body of work that is unique in its specific relevance to naturopathic and complementary medicine students and practitioners.

Limnology Climatology and Paleoclimatology of the East African Lakes

Limnology Climatology and Paleoclimatology of the East African Lakes

The large lakes of the East African Rift Valley are among the oldest on Earth and are vital resources for the people of their basins. They are unique among the large lakes of the world in terms of their sensitivity to climatic change rich and diverse populations of endemic species circulation dynamics and water-column chemistry and long continuous records of past climatic change. A comprehensive study of the large African lakes is long overdue. The scientific justification for such an effort is noted in the previous paragraph and is illustrated in great detail in this volume. Societal need for the sustainable utilization of these lakes offers an even more compelling reason for examination of biological food webs water quality and past climate variability in East Africa. The lakes provide the most important source of protein for the people of the African Rift Valley and fish populations are shifting dramatically in response to fishing pressure introduction of exotic species land use impact on water quality and perhaps climatic change. Current estimates of primary productivity the underpinning of the food resource are extremely crude and based on only a few spot measurements. | Limnology Climatology and Paleoclimatology of the East African Lakes
