Neuroprotective Effect of Antioxidants in the Brain
International Journal of Molecular Sciences, 2020 The brain is vulnerable to excessive oxidative insults because of its abundant lipid content, high energy requirements, and weak antioxidant capacity. Reactive oxygen species (ROS) increase susceptibility to neuronal damage and functional deficits, via ...

Plant polyphenols as dietary antioxidants in human health and disease
Oxidative Medicine and Cellular Longevity, 2009 Polyphenols are secondary metabolites of plants and are generally involved in defense against ultraviolet radiation or aggression by pathogens. In the last decade, there has been much interest in the potential health benefits of dietary plant polyphenols

Antioxidant Peptidomics Reveals Novel Skin Antioxidant System
Molecular & Cellular Proteomics, 2009 It is generally agreed that reactive oxygen species (ROS) contribute to skin aging, skin disorders, and skin diseases. Skin possesses an extremely efficient antioxidant system. This antioxidant activity is conferred by two systems: antioxidant enzymes and small molecules that can scavenge ROS by donating electrons.
