Zur Kenntnis des Vitamins-A aus Fischtranen.Helvetica Chim. Acta, 14, 1036-1040, 1931.In 1930 Karrer established the correct formula for carotene (the chief precursor of vitamin A), the first demonstration of the chemical structure of a vitamin. Shortly thereafter, he was able to determine the formula of vitamin A, and in 1931, he showed that vitamin A is structurally related to the carotenoids.
