In easier occasions, a chemist found a substance important to human well being that the physique couldn’t produce and known as it a “vitamine,” a portmanteau of “vital” and “amine” (because of a mistaken perception that this substance was an amino acid). Things received barely extra sophisticated when one other such substance was discovered, however the scientists dealt with it with aplomb: they proclaimed the first “vitamin A” and the second — do you see the place that is going? — “vitamin B.” Then got here C, and D, adopted by E, after which Ok, as a number of compounds in a row (F, G, H, I, and J, presumably), didn’t move vitamin muster.
But then issues began getting messy. When researchers started to appreciate that vitamin B was really a complete household of gear, related in type and performance, however distinctive in the roles they play in human well being. Instead of including extra letters (there weren’t that many left, and who knew the place this proliferation of Bs was going to finish), the namers turned to numbers: B1, B2, B3, B5, and so forth.
A number of issues right here. First, there’s no B-Four, which you could possibly charitably chalk as much as not eager to be liable for the following hypothetical dialog:
Parent: “Did you take your B-4?”
Child: “Did I take my what earlier than?”
Thank you, science.
Second, whereas there are eight B nutritional vitamins, there aren’t any B batteries, which feels suspicious to me.
And third, the Bs aren’t even named in chronological order. If you peruse the 1,098-page traditional, Handbook of Biochemistry and Molecular Biology, Fourth Edition, by Lundblad and McDonald, you’ll study that B12 was first recognized in 1926, whereas B3 wasn’t found till 1936.
