This book starts with a general introduction to phytochemistry, followed by chapters on plant constituents, their origins and chemistry, but also discussing animal-, microorganism- and mineral-based drugs. Further chapters cover vitamins, food additives and excipients as well as xenobiotics and poisons. The book also explores the herbal approach to disease management and molecular pharmacognosy and introduces methods of qualitative and quantitative analysis of plant constituents. Phytochemicals are classified as primary (e.g. carbohydrates, lipids, amino acid derivations, etc.) or secondary (e.g. alkaloids, terpenes and terpenoids, phenolic compounds, glycosides, etc.) metabolites according to their metabolic route of origin, chemical structure and function. A wide variety of primary and secondary phytochemicals are present in medicinal plants, some of which are active phytomedicines and some of which are pharmaceutical excipients.

For many years, the chemistry of vitamin B12 and its derivatives has been investigated for their inherent eco-friendly and nontoxic nature. This vitamin, also known as cobalamin, is an organic complex that contains a cobalt ion in its structure. Its derivatives are vital bio-inorganic cofactors and possess complex and rich photolytic properties, facilitated by their excited states. This book compiles and details cutting-edge research in the application of vitamin B12 as an environmentally benign catalyst for several organic reactions. It discusses the recent advances and current understanding of the photolytic properties of vitamin B12 derivatives from the perspective of the density functional theory (DFT). The book is of interest for anyone involved in nanotechnology, macromolecular science, cancer, and drug-delivery research.

This practical reference provides the most recent information available on every type of nutrient, including carbohydrates, fats, proteins, lipids, water and electrolytes, minerals and trace elements, and fat and water soluble vitamins. Entries examine the foods themselves, as well nutritional contents, chemical and biochemical structures, and metabolic pathways. A visually impressive volume, the text is enhanced with tables, formulae, diagrams, and illustrations. An extensive system of cross references illustrates the relationships of additives, natural toxins, and food processing to health and disease. The entries present detailed caloric and nutrient information on individual foods, including grains, pulses, nuts, seeds, vegetables, meats, fish, eggs, dairy product, oils and fats, herbs, spice, and beverages. This handy reference places nutrition in a broader health context by examining the composition and structure of the body absorption and metabolism of foods and nutrition related disorders such as rickets, osteoporosis, scurvy, gout, diabetes, malnutrition, and obesity. Readers can explore both naturally occurring and human made food toxins as well as food additives listings feature easy-to-follow nutrients from ingestion to incorporation and elimination, in addition to accessible tables of chemical, biochemical, and nutritional information that allow immediate comparisons of related items. The Nutrition and Health Dictionary is an invaluable reference of nutritionists, nurses, food scientists, allied health professionals, and other heath care providers. It is also an outstanding resource for students and researchers in nutrition and food science.
