Scientists at the University of Erlangen — Nuremberg (Germany) found that hydrochinone contained in chocolate, tea, wine and coffee, in combination with zinc to prevent oxidative stress and slow the aging process. About it reported in a press release on Phys.org.
The researchers showed that zinc activates the polyphenols contained in hydrogenosome group of compounds consisting of aromatic ring and two hydroxyl groups. As a result, the molecule begins to neutralize superoxide, which is an oxygen ion with an unpaired electron, and belongs to the radicals. Superoxides provoke the attack in the cell oxidative stress, when damaged proteins, lipids and DNA.
Zinc and polyphenols are combined, forming ORGANOMETALLIC compound which is able to function in the same way as the enzyme superoxide dismutase, which promotes dismutation of superoxide into oxygen and hydrogen peroxide.
According to one theory, it is accumulating because of free radicals cellular damage leads to aging. However, except for superoxide, an important role in this process is played also other radicals, including peroxides and peroxynitrite.
