Vitamin A is a fat-soluble vitamin which is important for normal vision, the immune system, and reproduction. Most vitamins have official scientific names, but letters and numbers began to be used in the early 20th for classification purposes. Scientists then knew of only two factors that needed to be present in a diet for an animal to survive in a lab; these were deemed fat-soluble A and water-soluble B. As more vitamins were discovered, they were classified by a letter - either alphabetically in order of discovery, or by a letter suggesting its role in nutrition.
