Book excerpt: Marine Antioxidants: Preparations, Syntheses, and Applications provides the most updated and comprehensive knowledge on utilizing marine-derived substances for cosmeceutical, pharmaceutical and nutraceutical developments. The book delivers the isolation procedures and biological activity of marine-derived antioxidant substances as discussed by international experts on antioxidant material from actinobacteria, crustaceans, diatoms, fish, microalgae, microbes, and mangrove-associated marine organisms and seagrasses. In addition, the book details marine-derived bioactive antioxidants substances in the form of proteins, peptides, polysaccharides and lipids. Finally, the book provides the latest information on the mechanistic pathways of antioxidant substances with various diseases and nutritional perspectives. This is an essential resource for marine biotechnologists and marine biologists who want to better understand isolation procedures and antioxidant applications. Researchers interested in pharmaceutical nutrients, polymer science, and cosmeceuticals industries scientists, as well as students and academics, will also benefit from this book. Explores under-utilized marine products for commercial applications Offers isolated information and biological applications of each identified marine antioxidant Discusses the latest approaches to treatments of diseases, such as diabetes, arthritis, and cancer using marine resources
