Ascorbic acid is a water-soluble vitamin found in fruits and vegetables such as citrus fruits and green peppers. It occurs as a white or slightly yellow crystal or powder with a slight acidic taste. It is an antiscorbutic product. On exposure to air and light it gradually darkens. In the dry state it is reasonably stable in air, but in solution it rapidly oxidizes. Ascorbic acid is a free radical, an antioxidant scavenger, and plays a major role in oxidation-reduction reactions.

Ascorbic acid is a cofactor for enzymes involved in the biosynthesis of collagen (essential for tissue maintenance and repair), carnitine, and neurotransmitters. Humans cannot synthesize ascorbic acid endogenously and a lack of dietary intake can lead to scurvy. Vitamin C is most frequently used as a nutritional supplement.
