    Fructose-Induced Carbonyl/Oxidative Stress in S. cerevisiae: Involvement of TOR by Bohdana V. Valishkevych, Ruslana A. Vasylkovska, Liudmyla M. Lozinska, Halyna M. Semchyshyn

    Published 2016-01-01
    “…Fructose is a more potent glycoxidation agent capable of producing greater amounts of reactive carbonyl (RCS) and oxygen species (ROS) than glucose. The increased RCS/ROS production, as a result of glycoxidation in vivo, is supposed to be involved in carbonyl/oxidative stress, metabolic disorders, and lifespan shortening of eukaryotes. …”
