Quantum Chemical Analyses of Carotenoids Antioxidant Potential

Research Paper from the year 2016 in the subject Chemistry - Other, , language: English, abstract: A different quantum analyses summary that have been used to assess the carotenoids free radical scavenging activity are arranged in this study and the most significant views are considered.

Carotenoids are capable to interact with reactive species of oxygen through transfer of electron, radical adduct constitution, abstraction of hydrogen atom and scavenging of singlet oxygen. Most investigations focus functional theory of density to compare the various carotenoids antiradical capacity with the ones that are most probed theoretically, such as beta-carotene and lycopene. An important number of these applications have been employed to comprehend the mechanism of electron transfer, and a helpful tool called the full-electron donor-acceptor map (FEDAM) was expanded to better appraise this mechanism.

Significant aspects that may influence the carotenoids radical scavenging activity, such as solubility and synergistic effects, are occasionally overlooked, and a higher number of such components should be probed.
