Biochemistry of Antioxidants: Mechanisms and Pharmaceutical

Natural antioxidants from fruits and vegetables, meats, eggs and fish protect cells from the damage caused by free radicals. They are widely used to reduce food loss and waste, minimizing lipid oxidation, as well as for their effects on health through pharmaceutical preparations.

Antioxidative properties of phenolic compounds and their

Two potential protective mechanisms of phenolic action have been proposed: non-specific interactions and specific . The non-specific actions are based on free radical scavenging capacity and metal chelation, owing to the presence of phenolic groups and the presence of 2¨C3 double bond and a 4-keto group in ring C (direct effects).

Other mode such as radical quenching via electron donation and singlet oxygen quenching are also known for the antioxidant activity of phenolic acids. Furthermore, phenolic acids are found ubiquitously and well documented for other health protective effects like antimicrobial, anticancer, anti-inflammatory, anti-mutagenic etc.

Phenolic Antioxidant

3.2.3.4 Antioxidants. Bisphenol (BPA) is a commonly used synthetic phenolic antioxidant that can slow the oxidative degradation of plastic products. The presence of BPA leached out from microplastics has been reported in both remote and urban beach microplastic samples, ranging from 1 to 729.9 ng/g [182].

Phenolic Compounds: Structure, Classification,

Abstract. Phenolic compounds are the most abundant antioxidants in the human diet. They have a considerable structural diversity, characterized by the hydroxyl groups on aromatic rings. According to the number of phenol rings and the structural elements that bind rings to one another, such compounds are grouped and classified as simple phenols

1. Introduction Recently, much research has been devoted to free radical chemistry. There are undeniable pieces of evidence that free radicals are responsible for the oxidative damage of biomolecules such as proteins, lipids, or nucleic acids in the structures of cell nuclei and molecular membranes.

Free radicals, natural antioxidants, and their reaction

The antioxidant enzymes convert dangerous oxidative products to hydrogen peroxide (H 2 O 2) and then to water, in a multi-step process in presence of cofactors such as copper, zinc, manganese, and iron. Non-enzymatic antioxidants work by interrupting free radical chain reactions.

Antioxidants and antioxidant methods: an updated overview

Antioxidants had a growing interest owing to their protective roles in food and pharmaceutical products against oxidative deterioration and in the body and against oxidative stress-mediated pathological processes. Screening of antioxidant properties of plants and plant-derived compounds requires appropriate methods, which address the mechanism of antioxidant activity and focus on the kinetics
