[This is an exerpt of a message from a read-only net.med participant.] Steve, I'm not sure you're involved or interested in this stuff, but I thought perhaps it added to the discussion over vitamin names and you might post it if you like. (I've tried to keep it very non-technical). With regards to vitamin naming history, 'vital amines', as these micronutrients were first thought to be got coined by Funk into the term vitamines. In the search for factors influencing reproduction, fat soluble substances were distinguished. Very nearly simultaneously factors were discovered that influenced bone integrity (vit D) and growth. The nomenclature started out with factor A, B (which was water soluble), C (present vitamin C), D, E, F and so on. Vitamin B turned out to be several things, hence Vitamin B1, B2, B3, etc. Many of the early factors however turned out to be the same as others or not vitamins at all. We are left with the fat soluble vitamins A,D,E and K and the water soluble vitamins C and B-complex. The B-complex vitamins have specific names but some (B1, B2, B6 and B12) still retain their 'number-names' for much of the general public. On another subject, you might clarify people's confusion over 'sugar', glucose vs fructose vs sucrose. Sucrose is a disaccharide composed of 2 monosaccharides, one molecule of glucose and one of fructose. Glucose could be thought of as 'blood sugar' and sucrose as 'table sugar'. -- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Dale M. Forsyth | Assoc.
