Β-Cryptoxanthin subject has role provitamin
Biology and medicine
In the human body, β-cryptoxanthin is converted to vitamin A (retinol) and is, therefore, considered a provitamin A.  As with other carotenoids, β-cryptoxanthin is an antioxidant and may help prevent free radical damage to cells and DNA, as well as stimulate the repair of oxidative damage to DNA.Recent findings of an inverse association between β-cryptoxanthin and lung cancer risk in several observational epidemiological studies suggest that β-cryptoxanthin could potentially act as a chemopreventive agent against lung cancer.  On the other hand, in the Grade IV histology group of adult patients diagnosed with malignant glioma, moderate to high intake of β-cryptoxanthin (for second tertile and for highest tertile compared to lowest tertile, in all cases) was associated with poorer survival.
