Ageing and a low life expectancy are caused, at least partly, by oxidative stress. A team of researchers led by Prof. Dr. Ivana Ivanović-Burmazović from the Chair of Bioinorganic Chemistry at FAU, together with researchers from the USA, have discovered that zinc can activate an organic molecule, helping to protect against oxidative stress. The results have now been published in Nature Chemistry*.
Zinc is a trace mineral we need in order to remain healthy. FAU researchers working together with Prof. Dr. Christian Goldsmith from Auburn University, Alabama, USA, have discovered that zinc can protect against the superoxide responsible for oxidative stress when taken together with a component found in foodstuffs such as wine, coffee, tea and chocolate. This component is a hydroquinone group found in polyphenols, in other words the plant substances responsible for smell and taste. Zinc activates the hydroquinone groups, producing natural protection against superoxide, a by-product of human cell respiration which damages the body’s own biomolecules, for example proteins or lipids, as well as the human genome. Superoxide is thought to have a role to play in the ageing process and a number of illnesses such as inflammation, cancer or neurodegenerative diseases.
