Comparative Biochemistry: A Comprehensive Treatise, Volume III: Constituents of Life — Part A focuses on the processes, methodologies, and mechanisms involved in the biological transformations of matter. Composed of contributions of authors, the book first gives emphasis to the comparative features of fatty acid occurrence and distribution. The formation of fatty acids and lipids in living organisms; naturally occurring fatty acids and lipids; relationship between types and distribution of fatty acids and their biological origin are considered. The text also looks at the structure and distribution of sterols, steroid metabolism of lipids, and the distribution and metabolism of phospholipids. The book focuses as well on the structure and occurrence of natural monosaccharides and oligosaccharides. The occurrence of commoner monosaccharides and oligosaccharides; the compositions, reactions, and characteristics of nucleosides, nucleotides, and nucleic acids; and chromatographic examinations of biological materials for free sugars are considered. The text also looks at the structure, metabolism, and distribution of terpenoids and quinones. The book is a vital source of information for readers wanting to study the processes, methodologies, and mechanisms involved in the biological transformation of matter.
