Antioxidant 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

Antioxidants are a class of chemical substances naturally found in our food which can prevent or reduce the oxidative stress of the physiological system. glutathione has antioxidant properties
The relative importance of the antioxidant and pro-oxidant activities of antioxidants is an area of current research, but vitamin C, which exerts its effects as a vitamin by oxidizing polypeptides, appears to have a mostly antioxidant action in the human body.
Antioxidant and antiviral activities of lipophilic
In addition to hydrogen atom donation, antioxidants may also inhibit oxidation through single electron transfer. The antioxidant can deactivate a free radical or reduce an oxidant by donating an electron and forming an antioxidant radical cation, followed by rapid and reversible deprotonation (Wright et al., 2001). The antioxidant radical

The impact of antioxidants on biodiesel oxidation stability
At antioxidant concentrations of 1000 mg/kg, an improvement in oxidation stability could be achieved with all antioxidants tested. Especially the antioxidants DTBHQ, IONOX 220, Vulkanox ZKF, Vulkanox BKF, and Baynox were able to significantly improve the oxidation stability, leading to stabilization factors between 1.89 and 13.07.

Antioxidant capacity was evaluated using four in vitro assays, namely ferric reducing antioxidant power, cupric reducing antioxidant capacity, Trolox equivalent antioxidant capacity and 2,2
Antioxidant Activity of Carnosic Acid and Methyl Carnosate
This study was aimed at evaluating the antioxidant activities of carnosic acid and its methyl ester, methyl carnosate, in inhibiting the formation and decomposition of hydroperoxides in bulk and emulsified corn oil triglycerides at 60 °C.
Endogenous and Dietary Indoles: A Class of Antioxidants
The highest antioxidant values were determined for melatonin, 5-hydroxytryptophan, trp-trp and 5-methoxytryptamine. Active indole compounds were consumed during the reaction with ABTS • + and some tetrahydropyrido indoles (e.g. harmaline and 1-methyl-1,2,3,4-tetrahydro-β-carboline-3-carboxylic acid ethyl ester) afforded the corresponding
