Fructation In Vivo: Detrimental and Protective Effects of Fructose

Abstract EN

There is compelling evidence that long-term intake of excessive fructose can have deleterious side effects in different experimental models.

However, the role of fructose in vivo remains controversial, since acute temporary application of fructose is found to protect yeast as well as animal tissues against exogenous oxidative stress.

This review suggests the involvement of reactive carbonyl and oxygen species in both the cytotoxic and defensive effects of fructose.

Potential mechanisms of the generation of reactive species by fructose in the nonenzymatic reactions, their implication in the detrimental and protective effects of fructose are discussed.
