Book Description
The Proteins: Composition, Structure, and Function, Second Edition, Volume II deals with fundamental properties of proteins, both in solution and in the solid state. This volume consists of five chapters that specifically cover the advances in understanding the structure and function of the protein molecule. The opening chapter presents interpretative procedures of experimental methods for determining protein conformation using X-ray crystallography, followed by an examination of the acid-base dissociations of proteins. The discussion then shifts to the investigation of interactions between protein molecules and other macromolecules, which is of significant importance in providing a chemical basis for many biological processes. A chapter considers first the synthesis, purification, and chemical properties of the polyamino acids. This chapter further describes their physicochemical properties in the solid state, in solution, and at interfaces, and lastly discusses their biological properties as high molecular weight substrates for proteolytic enzymes and as synthetic antigens, and their interaction with proteins and nucleic acids, with viruses, bacteria, blood components, and other biological systems. The use of polyamino acids in the study of the genetic code and the preparation and properties of polypeptidyl proteins are also covered. The concluding chapter focuses on X-ray analysis of protein structure. Organic chemists, biochemists, and researchers in protein-related fields will find this book invaluable

Book Description
Emulsifiers, also known as surfactants, are often added to processed foods to improve stability, texture, or shelf life. These additives are regulated by national agencies, such as the FDA, or multi-national authorities, such as the EEC or WHO. The amphiphilic molecules function by assisting the dispersion of mutually insoluble phases and stabilizing the resulting colloids, emulsions, and foams. Emulsifiers can interact with other food components such as carbohydrates, proteins, water, and ions to produce complexes and mesophases. These interactions may enhance or disrupt structures and affect functional properties of finished foods. In dairy processing, small molecule emulsifiers may displace dairy proteins from oil/water and air/water interfaces, which affects stability and properties of the foams and emulsions. In baked products, emulsifiers contribute to secondary functionalities, such as dough strengthening and anti-staling. Synthetic food emulsifiers suffer from the stigma of chemical names on a product’s ingredient statement. Modern consumers are seeking products that are “all natural.” Fortunately, there are a number of natural ingredients that are surface-active, such as lecithin, milk proteins, and some protein-containing hydrocolloids. Mayonnaise, for example, is stabilized by egg yolk. This book can serve as both a guide for professionals in the food industry to provide an understanding of emulsifier functionality, and a stimulus for further innovation. Students of food science will find this to be a valuable resource.

Book Description
Molecular Mechanisms of Protein Biosynthesis is a collection of papers dealing with cell-free systems at the molecular level, including transfer RNA; the initiation, elongation, and termination processes; ribosome structure and function; mRNA translation; and DNA-directed in vitro protein synthesis. A couple of papers review tRNA, aminoacyl-tRNA synthetases, and aspects of ribosome structure. One paper discusses affinity labeling in the study of binding and catalytic sites of large complex and heterogeneous systems such as the ribosome. The investigator should be aware of the chemically reactive or photoactivatible analogue reacting specifically with one or more ribosomal components. This reaction should be determined if it is dependent on the correct binding of the affinity label at the functional site. Another paper describes the series of reactions in protein synthesis as the process by which the ribosome moves relative to the messenger RNA. Other papers discuss messenger RNA and its translation, DNA-dependent cell-free protein synthesis, as well as the genetics of the translational apparatus. The collection will benefit microbiologists, biotechnologists, and academicians connected with the biological sciences.
