The Search for Anticarcinogenic Organoselenium Compounds from Natural Sources

open access: yes, 1998
Consumption of Se-enriched plants or yeast-based nutritional supplements is reported to reduce the risk of cancer. Separation and identification of natural organoselenium compounds in these plants is essential to understand the basis for their biological
