Fructose protects baker's yeast against peroxide stress: potential role of catalase and superoxide dismutase

Abstract: The negative effects of fructose due to its chronic consumption are well documented, while short‐term application of fructose is found to protect different types of cells against oxidative stress. Reactive oxygen species (ROS) are suggested to mediate both the cytotoxic and defensive effects. Here, we compare the influence of glucose and fructose on yeast under H2O2‐induced stress. Under control conditions, fructose‐grown comparing with glucose‐grown yeast demonstrated higher metabolic activity and ROS level. … Show more

“…However, they can be altered by ROS addition in a concentrationdependent manner. Although at first glance may seem paradoxical, an increase in concentration of the inducer enhances cell survival and activity of antioxidant enzymes (zone II) [5,54]. These effects are primarily related to the activation of many cellular processes, particularly directed to increase cell resistance to oxidative or general stresses.…”

“…Decreased activities of the enzymes are usually discussed from the point of view of enzyme inactivation by ROS. Indeed, many antioxidant and associated enzymes have been shown to be inactivated by ROS [7,22,25,36,54,55,72]. Specific mechanisms may differ substantially, but a decrease in the activity is a common event.…”
