Biological Ultrastructure [PDF ebook] 

Biological Ultrastructure focuses on the ultrastructure of biological systems, including microscopy and the roles of amino acids, lipoproteins, and carbohydrates. The manuscript first offers information on the methods in ultrastructural research and the principles of molecular structure. Topics include application of electron microscopy and x-ray diffraction, electronic theory of valency, spatial arrangement, and aggregation of molecules and interaction with water. The book then examines the role of proteins and lipids, including amino acids, polypeptide chains, natural lipoproteins, and structure and properties of isolated lipid molecules. The publication underscores the role of carbohydrates and nucleic acids, as well as monosaccharides, disaccharides, polysaccharides, structure of nucleic acids, viruses, and cell nucleus chromosomes and genes. The text also takes a look at the role of ultrastructure in biology and medicine and the role of mineral salts. The manuscript is a valuable source of data for readers interested in biological ultrastructure.
