Vitamin A is a vitamin that is needed by the retina of the eye in the form of a specific metabolite, the light-absorbing molecule retinal. This molecule is absolutely necessary for both scotopic and color vision. Vitamin A also functions in a very different role, as an irreversibly oxidized form retinoic acid, which is an important hormone-like growth factor for epithelial and other cells.

Vitamin A and derivatives in medical use:

Retinyl palmitate has been used in skin cremes, where it is broken down to retinoic acid, which has potent biological activity, as described above.

The retinoids, (for example, 13-cis-retinoic acid) constitute a class of chemical compounds that are related chemically to retinoic acid, and used in medicine to modulate gene functions in place of this compound. In general, like retinoic acid itself, these compounds do not have full vitamin A activity.

Ascorbic acid is a sugar acid with antioxidant properties. Its appearance is white to light-yellow crystals or powder, and it is water-soluble. One form of ascorbic acid is commonly known as vitamin C.

Uses

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, or heat destroys ascorbic acid, so it must be stored in a dark, cold, and non-metallic container.

The L-enantiomer of ascorbic acid is also known as vitamin C. The name "ascorbic" comes from its property of preventing and curing scurvy.

Ascorbic acid and its sodium, potassium, and calcium salts are commonly used as antioxidant food additives. These compounds are water-soluble and thus cannot protect fats from oxidation: For this purpose, the fat-soluble esters of ascorbic acid with long-chain fatty acids (ascorbyl palmitate or ascorbyl stearate) can be used as food antioxidants.
