Astaxanthin:Chemical Structure,Biological Functions and Usage

This article reviews the research progress of astaxanthin in the last 10 years.Astaxanthin exists in various forms and has chemical features to protect from oxidative damage by quenching singlet oxygen and dissipating the energy as heat,and scavenging radicals to prevent or terminate chain reactions.Many human diseases and degenerative processes have been linked in a way to the action of free radicals,which may enhance the progression of diseases and may inhibit the body's own defense and repair processes.Astaxanthin is now primarily used as a colorant added to feeds for fish and poultry to benefit their reproduction and health.
