Vitamin B
« on: January 15, 2021, 11:16:41 AM »
Hello!

My question is, if the B vitamins are all Amino acids. B1 for example: Thiamine, the name ends with ine, so I assume it's an Amino acid? I'm not sure if that's correct.
Vitamins B3, its name end with -in and -ide, is it both an Amino acid and Amid?
B6: Pyridoxine and pyridoxol- is that an Amino acid and an alcohol?
I'm a bit confused  ???
Thank you!!

First, it is not true that thiamine is an amino acid. Second, the names of vitamins (with letters A, B, etc.) are common names and names are not the basis of systematic names. Nicotinamide is also a common name - the correct chemical name is pyridine-3-carboxamide. Some vitamins are derived from amino acids.

IIUC it was once thought that all of the vitamins were amines, and the term was originally "vitamins."  This may explain some of their common names.
