Application

Ascorbic acid is easily oxidized and so is used as a reductant in photographic developer solutions (among others) and as a preservative.

Exposure to oxygen, metals, light, and heat destroys ascorbic acid, so it must be stored in a dark, cold, and non-metallic container.

The L-enatiomer of ascorbic acid is also known as vitamin C. The name "ascorbic" comes from its property of preventing and curing scurvy primates, including humans, and a few other species in all divisions of the animal kingdom, notably the , have lost the ability to synthesize ascorbic acid, and must obtain it in their food.

Ascorbic acid and its sodium, potassium, and calcium salts are commonly used as antioxidant food aadditives. These compounds are water-soluble and thus cannot protect from oxidation: For this purpose, the fat-solublesesters of ascorbic acid with long-chain fatty acids (ascorbyl palmitate or ascorbyl stearate) can be used as food antioxidants. Eighty percent of the world''s supply of ascorbic acid is produced in China.
