Mammalian Protein Metabolism, Volume IV is an 11-chapter text that describes the regulation of protein metabolism in mammals, both at the subcellular level and at the level of the intact organ and of the whole animal. The first two chapters deal with the fundamental control mechanisms in the synthesis and turnover of proteins, followed by chapters on the mode of action of hormones on protein metabolism and on the role of free amino acid pools in regulation. These topics are followed by discussions on the regulation of individual amino acid pathways and the diurnal rhythms in protein metabolism. The final chapters explore the regulation of protein metabolism in four major organs and tissues of the body, including the gastrointestinal tract, liver, kidney, and musculature. This book will be of great benefit to biologists, researchers, and biology students.
