Role	Description
ferroptosis inhibitor	Any substance that inhibits the process of ferroptosis (a type of programmed cell death dependent on iron and characterized by the accumulation of lipid peroxides) in organisms.
catalyst	A substance that increases the rate of a reaction without modifying the overall standard Gibbs energy change in the reaction.
radical scavenger	A role played by a substance that can react readily with, and thereby eliminate, radicals.
