Vitamin I[edit]

I doubt the hikers' standing-joke slang term "Vitamin I" for Ibuprofen needs any mention in the article, tho i am turning that redir into a Dab. --Jerzy·t 2005 July 5 18:00 (UTC)

Actually, I'll take care of Vitamin I in Vitamin.

A few things[edit]

1.Pangamic acid is better known as dimethylglycine: http://www.pdrhealth.com/drug_info/nmdrugprofiles/nutsupdrugs/dim_0097.shtml Note: Pangamic acid is not DMG as many sorces claim - please see 'Merck Index - Susan Budavavi' or 'Chemical Abstracts' for proper structure.

2.Also,what is the reference for B-10 being Pteroylmonoglutamic acid and "other vitamins"? Pteroylmonoglutamic acid is synonymous with Pteroylmonoglutamate and Folic Acid ( http://www.google.com/search?q=cache:ymlKMg7d2wwJ:www.nap.edu/nap-cgi/morehits.cgi%3Fdisplay%3Dtext%26isbn%3D0309069890%26term%3Dfolic%2Bacid%26file%3D113-149.htm+pteroylmonoglutamate&hl=en&gl=us&ct=clnk&cd=11)so I made the Pteroylmonoglutamic acid page redirect to the folic acid page but maybe they should just change the name to folic acid.

3.One reference(though not a good one) says B-10 is PABA: http://www.althealth.co.uk/services/info/supplements/vitamin_b10_1.php So does the Vitamin wikipedia page: http://en.wikipedia.org/wiki/Vitamin another is http://newstaff.com/nutrientscatalog/designations.html but again there are no references!

4. Vitamin H is listed as inositol but most searches list both vitamin H and B-7 as synonyms for biotin: http://www.vitamins-supplements.org/biotin.php

^.Briggs who anounced B10(chick feathering) & B11(chick Growth) in 1943 belived them to be forms of Folic acid but not Pteryl-mono-glutamic acid as thay had a different line on chromotography than Pteryl-mono-glutamic acid or B12, also Pteryl-mono-glutamic acid dose not pass his isolation process or solubilities for B10 & B11 (PABA & 'Pteryl-hepta-glutamic acid' do). I have seen over 20 rerfrences of diffrent authors in Europe (French, Spanish & Italian; mostly french including Medical Dictionaries; non French ones refer to French Merck Index for B10 as PABA) claiming B10 is PABA. Very few in English. The refrence that says B11 is 'Pteryl-hepta-glutamic acid' is "Groot Woorden Boek der Geneeskunde(Encyclopedia Medica)" by H. De Haan & W. Dekker 1957 Bertei

Friend of mine later saw a journal 'General Vitamin Review - 1947' of 'The University of Maryland' (Hard to get) that 'George M Briggs' using Gel Chromotography found Vitamin B11 to be 'Pteryl-hepta-glutamic acid' Bertei — Preceding unsigned comment added by 114.76.76.26 (talk) 10:29, 28 October 2013 (UTC)

Someone may also want to add some info about the relationship between PABA and folic acid ( http://www.drlera.com/vitamins/vitamin_bx.htm).

Although this has been suspected in the past, Vitamin B10 and B11 can not posibly be Vitamin R and Vitamin S. B10 and B11 are soluble in ethanol. vitamin R and Vitamin S are NOT soluble in ethanol. (some folates are not soluble in alcohol like folinic acid and PGA; some folates are soluble in alcohol like PHGA)Bertei

This page is a mess! --Renwick

list of Vitamins[edit]

Is there any real purpose to the list of B-vitamins as it is subsequently listed in uses.? Alexllew

Choline[edit]

The section on Choline has a completely unsourced claim that it is only necessary for the survival of some mutants. This contrary to wikipedia's own entry on choline. Until someone provides a source I am removing it for the purpose of internal consistency. 173.160.220.249 (talk) 15:23, 7 August 2013 (UTC)

Primary production?[edit]

I've been reading that plankton are limited (and prevented) from growing by a lack of B-vitamin in ocean waters. Where does this B-vitamin come from? I see a vague reference to plant production in sources, but surely plankton existed prior to plants being washed into the ocean...

Shouldn't Vitamin B9 be called Folate?[edit]

Vitamin B9 is listed as folic acid but folic acid is the inert, cheap, commercially available form. It needs to be converted to folate in order to be biologically active. Folate is also available commercially but its more expensive.Teknozilla (talk) 10:06, 15 May 2014 (UTC)Teknozilla
