Eschew Beaucoup Q

Katharine Miller;2002/1/nf1

Abstract: Everything that once used oxygen to produce energy contains a multipurpose lipid called ubiquinone or coenzyme Q, but Q-loaded meals might be more curse than blessing: Adult roundworms live longer without dietary Q, according to new research. Because coenzyme Q can foster the production of reactive oxygen species (ROS), molecular mischief-makers that damage a wide range of cellular molecules, the results might support the view that ROS promote an animal's demise. The work, published in the 4 January issue of Science (p. 120), also contributes to the notion that aging results from the activity of genes that benefit an animal early in life--so that it reaches reproductive maturity--but harm it later.
