Quizplus · Accepted Answer

The information provided suggests that the substance isolated from charcoal-grilled meat is an oxidant, as it causes the breakdown of cells' plasma membranes. Additionally, the fact that the reaction can be prevented by adding an antioxidant (vitamin C) further supports this conclusion. This experiment was conducted in vitro, meaning it was done in a controlled laboratory setting with cells outside of the body. There is no evidence to suggest that this substance has potential as a cancer treatment or that vitamin C has pro-oxidant activity in vivo experiments.
