Importance Of Selenium In The Environment And Human Health

Importance of Selenium in the Environment and Human Health

Analytical Methods in the Determination of Bioactive Compounds and Elements in Food

Most bioactive compounds have antioxidant activity, particularly tocochromanols, phenolics (flavonoids and phenolic acids), methylxantines and capsaicinoids. Some of these compounds have also other properties important for human health. For example, vitamin E protects against oxidative stress, but it is also known for its “non-antioxidant” functions, including cell signalling and antiproliferation. Selenium compounds and indoleamins are the components of the antioxidant enzymes. Selenium makes vitamin E acquisition easier and controls its physiological functions. In taking part in enzymatic reactions and protecting the cell against free radicals, selenium shows immunomodulative, antiphlogistic, and antiviral activity. Capsaicinoids possess not only antioxidant, but also antibacterial, analgesic, weight-reducing and thermoregulation properties. Studies have also demonstrated their gastroprotective and anticancer properties. Analytical Methods in the Determination of Bioactive Compounds and Elements in Food explores both the influence of particular compounds on human health and the methods used for their determination. Chapters describe various aspects of food and plant analysis, including chromatographic and non‐chromatographic approaches as well as hyphenated techniques. Readers of this book will gain a comprehensive understanding of the important groups of bioactive compounds relevant to human health.

Measurement, Analysis and Remediation of Environmental Pollutants

This book discusses contamination of water, air, and soil media. The book covers health effects of such contamination and discusses remedial measures to improve the situation. Contributions by experts provide a comprehensive discussion on the latest developments in the detection and analysis of contaminants, enabling researchers to understand the evolution of these pollutants in real time and develop more accurate source apportionment of these pollutants. The contents of this book will be of interest to researchers, professionals, and policy makers alike.
