Question

There are Vitamins A through K. But why do they leave out naming any of them with the letters, F,G,H,I, and J? Just A through E, then K.

Answer 1

The Naming of Vitamins

Orignally it was not imagined that there would be so many different vitamins. Back in 1913, the scientists came up with a naming system that was based on two groupings; those that would dissolve in fat, called "Fat soluble A" vitamins, and those that would dissolve in water, referred to as
the "Water Soluble B" vitamins.

The vitamin compounds were named in order of discovery, and when it was determined that there were many, they moved on to C, D, E and so forth. Many times a substance thought to be a vitamim was found to not be essential. When this happened, the letter was passed by and the next one used.

In some cases, the first letter for the function of the compound was used in its name. For example vitamin K comes from the German "koagulation" (coagulation), which is a term that stands for the clotting of blood, a process in which the substance called vitamin K was found to play a role.

The "B" vitamins were thought to be only one compound. But when it was found that there were many involved, they were named vitamin B1, B2 and so forth. Again, when a compound thougt to be a vitamin proved to not have any essential quality, the number was abandoned.
