Sirtuins are members of a class of enzyme, deacetylases which remove acetyl groups from proteins. Sirtuin activators increase yeast life span by 70%.
It is possible but not absolute that a compound resveratrol may activate sirtuins. A possible mechanism for the putative activity of resveratrol is similar to caloric restriction.
It is rumoured that resveratrol is the component of red wine that has health benefits.
