The mechanism(s) of action of antioxidants: From scavenging …
This review provides a summary on the role of the in vivo metabolic changes and the oxidized metabolites on the mechanisms behind the bioactivity of antioxidants. A special attention is given to metabolites described as products of biomimetic oxidative chemical reactions, which can be considered as models of free radical scavenging.
Antioxidant Compounds and Their Antioxidant Mechanism
2019年3月22日 · 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), …
The mechanism(s) of action of antioxidants: From scavenging …
Dietary antioxidants interfere with biological processes through several mechanisms of action, including free radical scavenging, modulation of redox signaling pathways and transcription factors, and the formation of sometimes very complex metabolite fingerprints. All these mechanisms are clearly interconnected at multiple levels.

Antioxidants: Classification, Natural Sources, Activity/Capacity ...
It should be remembered that antioxidants can act through various mechanisms, not only scavenging radicals, but also sequestering transition metal ions, decomposing hydrogen peroxide or hydroperoxides, quenching active pro-oxidants, and enhancing endogenous antioxidant defense but also by repairing the resulting cellular damage.
Mechanism of Antioxidant Activity | SpringerLink
2021年8月28日 · The mechanism of antioxidants activity is based on the redox process, i.e., where oxidation and reduction process occurs simultaneously. Redox reactions are very common and important chemical reactions occurring in our day-to-day life.
Understanding the chemistry behind the antioxidant activities …
2015年8月28日 · Antioxidants are the main defence mechanism of the body acting as free radical scavengers [8]. They are produced within the body and include dismutase, peroxidase, and catalase enzymes, as well as glutathione and cytochrome [9]. Other main sources of antioxidants are fruits and vegetables, (all containing phenolic compounds).
Understanding mechanisms of antioxidant action in health and
This Review describes the mechanisms of action of antioxidants synthesized in vivo, antioxidants derived from the human diet and synthetic antioxidants developed as therapeutic agents, with a focus on the gaps in our current knowledge and the approaches needed to close them.
Exploring the Antioxidant Mechanisms of Nanoceria in …
21 小时之前 · An excess of reactive oxygen species (ROS), leading to oxidative stress, is a major factor in aging. Antioxidant therapies are considered crucial for delaying aging. Nanoceria, a nanozyme with antioxidant activity, holds significant potential in protecting cells from oxidative stress-induced damage. This research examines the neuroprotective role of nanoceria on HT22 cells subjected to ...
