Download or read book Phenolic Antioxidants and Health Benefits written by U.D. Chavan and published by Scientific Publishers. This book was released on 2018-02-01 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is mainly based on the latest research results and applications of phenolic and polyphenolic compounds. Phenolic compounds, ubiquitous in plants, are an essential part of the human diet and are of considerable interest due to their antioxidant properties and potential beneficial health effects. These compounds range structurally from a simple phenolic molecule to complex high-molecular-weight polymers. There is increasing evidence that consumption of a variety of phenolic compounds present in foods may lower the risk of health disorders because of their antioxidant activity. When added to foods, antioxidants control rancidity development, retard the formation of toxic oxidation products, maintain nutritional quality and extend the shelf-life of products. Due to safety concerns and limitation on the use of synthetic antioxidants, natural antioxidants obtained from edible materials, edible by-products and residual sources have been of increasing interest. This contribution summarizes both the synthetic and natural phenolic antioxidants, emphasizing their mode of action, health effects, degradation products and toxicology. In addition, sources of phenolic antioxidants are discussed in detail.

Download or read book Health Benefits of Phenolic Antioxidants written by Aman B. Upaganlawar and published by . This book was released on 2022-09-26 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Free radicals are continuously produced in cells as a part of normal cellular function. However, excess generation of free radicals plays a critical role in the pathophysiology of many disease conditions, especially cancer, atherosclerosis, Alzheimer's disease, etc. Oxidation is a major chemical process that produces free radicals and initiates chain reactions that cause cellular damage. Compounds that inhibit oxidation are called antioxidants; phenols are known to possess excellent antioxidant properties. Phenolic compounds are abundant in plants in a wide variety of chemical structures. Natural phenolic compounds include phenolic acids and ester derivatives, flavonoids and benzopyran derivatives, quinones, tannins, lignins, lignans, stilbenes, essential oils, chalcones, etc. Nutraceuticals, in the name of dietary supplements and functional foods, are being consumed as prophylactics for the prevention of many diseases throughout the world. Most of these products are polyphenols; hence, this book provides an insight on therapeutic potentials of natural and synthetic polyphenols, emphasizing their pharmacology.

Download or read book Effect of Phenolic Compounds on Human Health written by Elena González-Burgos and published by Mdpi AG. This book was released on 2022-01-21 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phenolic compounds are non-essential dietary compounds that are found in many vegetables (i.e. onion, cabbage, broccoli and parsley), fruits (i.e. cherries, grapes, berries and pears), cereals and beverages (i.e. red wine, tea and chocolate). These heterogeneous compounds are produced as secondary metabolites. Structurally, these compounds are characterized by comprising an aromatic ring with one or more hydroxyl groups that can be classified into two groups: flavonoids and non-flavonoids. Phenolic compounds have received considerable attention for its health-promoting properties in many chronic disorders including diabetes, cardiovascular diseases, cancer and neurodegenerative diseases, among others. These health benefits are mainly attributed to its antioxidant properties. Phenolic compounds act as antioxidant by scavenging free radicals, metal chelation and endogenous antioxidant system upregulation (enzymatic antioxidants such as catalase, superoxide dismutase and glutathione peroxidase and non-enzymatic antioxidants such as glutathione). The consumption of exogenous medicinal plants and food rich in phenolic compounds represent a promising therapeutically to prevent many chronic diseases and improve health. This Special Issue entitled "Effect of Phenolic Compounds on Human Health" include research articles and review articles on phenolic compounds and its role in health (i.e. flavonoids and diabetes, polyphenols and liver diseases, polyphenols and obesity, polyphenols and cardiovascular diseases and polyphenols and neuroprotection).

Download or read book Lipid Oxidation written by Edwin N. Frankel and published by Elsevier. This book was released on 2014-01-23 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this second edition, Edwin Frankel has updated and extended his now well-known book Lipid oxidation which has come to be regarded as the standard work on the subject since the publication of the first edition seven years previously. His main objective is to develop the background necessary for a better understanding of what factors should be considered, and what methods and lipid systems should be employed, to achieve suitable evaluation and control of lipid oxidation in complex foods and biological systems. The oxidation of unsaturated fatty acids is one of the most fundamental reactions in lipid chemistry. When unsaturated lipids are exposed to air, the complex, volatile oxidation compounds that are formed cause rancidity. This decreases the quality of foods that contain natural lipid components as well as foods in which oils are used as ingredients. Furthermore, products of lipid oxidation have been implicated in many vital biological reactions, and evidence has accumulated to show that free radicals and reactive oxygen species participate in tissue injuries and in degenerative disease. Although there have been many significant advances in this challenging field, many important problems remain unsolved. This second edition of Lipid oxidation follows the example of the first edition in offering a summary of the many unsolved problems that need further research. The need to understand lipid oxidation is greater than ever with the increased interest in long-chain polyunsaturated fatty acids, the reformulation of oils to avoid hydrogenation and trans fatty acids, and the enormous attention given to natural phenolic antioxidants, including flavonoids and other phytochemicals.
