Prooxidant Actions of Carotenoids in Biologic Systems

Palozza, Paola·2009·Nutrition Reviews

Abstract

The potential for carotenoids to modulate chronic disease risk is currently under investigation, and renewed interest has been placed on achieving a better understanding of the mechanisms of action of carotenoids in biologic systems. Available data currently show that the antioxidant activity of these compounds may shift into prooxidant activity, depending on the redox potential of the carotenoid molecules as well as on the biologic environment in which they act. The prooxidant potency of these compounds is determined by several factors, including oxygen tension, carotenoid concentration, and interactions with other antioxidants. Prooxidant activity can induce either beneficial or harmful results in biologic systems and influence the development of human chronic diseases.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Depending on the redox potential of lycopene and the surrounding environment, its antioxidant activity may shift to prooxidant activity.

    “However, depending on the redox potential of lycopene and the surrounding environment, its antioxidant activity may shift to prooxidant activity [56, 57].”
  • EDTA used for HaCaT trypsinization can induce Fenton-chemistry mediated radical damage.

    “The chelating agent used for HaCaT trypsinization was ethylenediaminetetraacetic acid (EDTA) which can induce Fenton-chemistry mediated radical damage.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
