Phenolic compounds can be considered as the most important bioactive compounds in Mediterranean diet. However, many of the complex connections between phenols antioxidant reactivity and their molecular structure remain unsolved. To shine light on these issues, the antioxidant reactivity of 15 relevant phenolic compounds was studied. Two different analytical approaches were combined: (a) the

Biochemistry of Antioxidants: Mechanisms and Pharmaceutical

The reaction of antioxidants, ArOH, with peroxyl, ROO ?, radicals might take place through different mechanisms depending on structure of the antioxidant and the solvent: one-step hydrogen atom transfer (HAT), electron transfer-proton transfer (ET-PT), proton-coupled electron transfer (PCET) or sequential proton-loss electron transfer (SPLET), Figure 4.

Recent Developments in Effective Antioxidants: The Structure and

Antioxidants are molecules capable of counteracting and slowing down the oxidation reactions of substances that can form free radicals. They neutralize or divert ROS such as CAT, SOD, and GPx, interrupt free radical reactions, and destroy ROS such as vitamin E, C, flavonoids, glutathione, uric acid, and also bind/inactivate of metal ions (catechins, ferritin, and ceruloplasmin).

Vitreous Antioxidants, Degeneration, and Vitreo-Retinopathy: Exploring

Abstract. The transparent vitreous body, which occupies about 80% of the eye¡¯s volume, is laden with numerous enzymatic and non-enzymatic antioxidants that could protect the eye from oxidative stress and disease. Aging is associated with degeneration of vitreous structure as well as a reduction in its antioxidant capacity.

Revealing and predicting the relationship between the molecular

Molecular planarity is a crucial characteristic of molecules that influences the conjugation ability of the ¦Ð electrons in ¦Ð-conjugated systems (Sobereva, 2021). This is closely related to properties such as photophysical (Nijegorodov et al., 2006) and molecular aromaticity antioxidant (Todorova et al., 2013; Xiao et al., 2021) behaviors
