Chemical and molecular mechanisms of antioxidants
Intracellular antioxidant enzymes and intake of dietary antioxidants may help to maintain an adequate antioxidant status in the body. In the past decades, new molecular techniques, cell cultures and animal models have been established to study the effects and mechanisms of antioxidants on ROS.

Antioxidants: Mechanisms of Action and Effectiveness
Brunswick Labs knows antioxidants. Here’s some knowledge sharing on the science, history, types, and function of antioxidants. Antioxidants: Mechanisms of Action and Effectiveness The first connection between the protective role of antioxidants against age and disease-induced damage to cells and biological molecules, DNAs, lipids and proteins, was made in the late 1980s and early 1990s.…

Hormetic and Mitochondria-Related Mechanisms
According to our view, the need of “so-called” antioxidants begins upon aging (i.e., when innate antioxidant mechanisms start to have some dysfunctions and alter well-being). Then, the search for interventions to keep healthiness is of vital importance and, in this sense, “antioxidants” have a huge potential.

Send InquiryAntioxidant Compounds and Their Antioxidant Mechanism
An antioxidant is a substance that at low concentrations delays or prevents oxidation of a substrate. Antioxidant compounds act through several chemical mechanisms: hydrogen atom transfer (HAT), single electron transfer (SET), and the ability to chelate transition metals. The importance of antioxidant mechanisms is to understand the biological meaning of antioxidants, their possible uses ...

Antioxidant Property of Coffee Components: Assessment
and the mechanism of the reaction is determined by the antioxidant’s structure and solubility, the partition coefficient and solvent polarity. Examples of HAT-based assays include ABTS and ORAC. Examples of SET-based assays include DPPH and FRAP [7].

Free radicals, natural antioxidants, and their reaction
The reaction mechanisms of the antioxidant assays are briefly discussed (165 references). The scope of this article is limited to the natural antioxidants and the in vitro assays for evaluation of their antioxidant properties. Conflicts of interest The author declares no conflict of interest.

This results predominantly in adduct formation but a range of further oxidation products are formed by oxidation of the quinone- methide (III); 2. at [BHBM]/[tBuOOH] < 1 radical reactions are suppressed due to the formation of sulphur oxides and acids which trap radicals and remove hydro- peroxides in a non-radical process.
