Molecular and Cellular Biology of the Vitamins is a key resource describing how vitamins function as physiologically active molecules at the cellular level. The contents of the book are divided into four sections including a thorough introduction; biological perspectives; fat-soluble vitamins; and water-soluble vitamins. Vitamin chapters cover information on chemical structures; intestinal absorption; plasma transport and metabolism; biochemical and physiological actions; regulations of gene expression; immunological properties; deficiency-related diseases. The 'perspectives' chapters facilitate the understanding of vitamin biology; including the theory of biochemistry, physiology, endocrinology, molecular genetics, and immunology.Features· Facilitates learning and understanding through a logical flow of information.· Discusses vitamin 'behavior' across a wide range of biological disciplines.· Discusses immunological and deficiency-related diseases including coronary artery disease, diabetes and cancer; and potential toxicity.Molecular and Cellular Biology of the Vitamins appeals to those involved in vitamin research or teaching, postgraduate students studying nutrition or health-related topics, health practitioners, and scientists.

To achieve and maintain optimal health, it is essential that the vitamins in foods are present in sufficient quantity and are in a form that the body can assimilate. Vitamins inFoods: Analysis, Bioavailability, and Stability presents the latest information about vitamins and their analysis, bioavailability, and stability in foods.The contents of the book is divided into two parts to facilitate accessibility and understanding. Part I, Properties of Vitamins, discusses the effects of food processing on vitamin retention, the physiology of vitamin absorption, and the physiochemical properties of individual vitamins. Factors affecting vitamin bioavailability are also discussed in detail. The second part, Analysis of Vitamins, describes the principles of analytical methods and provides detailed methods for depicting individual vitamins in foods. Analytical topics of particular interest include the identification of problems associated with quantitatively extracting vitamins from the food matrix; assay techniques, including immunoassays, protein binding, microbiological, and biosensor assays; the presentation of high-performance liquid chromatography (HPLC) methodology illustrated in tables accompanied by step-by-step details of sample preparation; the explanation of representative separations (chromatograms) taken from original research papers are reproduced together with ultraviolet and florescence spectra of vitamins; the appraisal of various analytical approaches that are currently employed. Comprehensive andcomplete, Vitamins in Foods: Analysis, Bioavailability, and Stability is a must have resource for those who need the latest information on analytical methodology and factors affecting vitamin bioavailability and retention in foods.
