What does antioxidant C mean?

Why is vitamin C called ascorbic acid?

Later on, Szent Györgyi and Haworth chemically identified “C” as ascorbic acid, and named it so because ascorbic means “anti-scurvy.” Over the next century, what we now know as vitamin C became one of the most popular drugs in human history.

Vitamin C is called an antioxidant because electrons from vitamin C can reduce oxidized species, or oxidants. However, the same electrons from ascorbate can reduce metals such as copper and iron, leading to formation of superoxide and hydrogen peroxide, and subsequent generation of reactive oxidant species.
