Lycopene: A Biologically Important Carotenoid for Humans?

Stahl, Wilhelm, Sies, Helmut·1996·Archives of Biochemistry and Biophysics

Abstract

Lycopene is a carotenoid present in human blood (approximately 0.5 micromol/liter plasma), and the tissue levels vary from 1 nmol/g wet wt in adipose tissue to up to 20 nmol/g wet wt in adrenals and testes. Its biological activities include antioxidant activity (singlet oxygen quenching and peroxyl radical scavenging), induction of cell-cell communication, and growth control, but no provitamin A activity. Epidemiological studies suggest protective effects of lycopene on some types of cancer, e.g., prostate cancer. In vitro and in vivo studies on growth of tumor cells support this conclusion. The major sources of lycopene for the human are tomatoes and tomato products, and bioavailability from different food items varies considerably. Lycopene oxidation products have recently been identified in human serum. Suggested health effects of lycopene require further investigation.

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.
