“

Serum and plasma vitamin C measurements do not correlate well with tissue levels while lymphocyte vitamin C levels provide the most accurate assessment of the true status of vitamin C stores and are not affected acutely by circadian rhythm or dietary changes.”

I don't see any real reason for having a seperate article on ascorbic acid, because vitamin C and ascborbic acid are one and the same, as pointed out in this article. Also, a bunch of chemical properties are already included, so I suggest removing sentences aluding to a non-existent ascorbic acid article. I'll leave that to the original authors though. I don't know how to wrap text around images, so the image I added is centered with nothing around it: a waste of space. Feel free to fix this. David E. Volk 16:37, 31 July 2007 (CDT)

Proposition: creation of the "Discovery of vitamin C"/"Discovery and history of vitamin C" page

The lengthy explanations on the history of vitamin c are interesting but could be displayed in a separate article. CZ has the article : "Discovery of pennicilin". I consider that "Discovery of vitamin C" would be an interesting page in its own right and could be the place to explore those problems surrounding vit. C's discovery and patenting and related issues (e.g. how scurvy was gradually accepted, how nascent globalisation of trade enabled the provision of never before seen amounts of vit. C in the northern latitudes, etc.). The page could also be more accurately called : "Discovery and history of vitamin C". A redirect from "Discovery of vitamin C" to "Discovery and history of vitamin C" or "History of vitamin C" could be used. Pierre-Alain Gouanvic 16:57, 13 November 2007 (CST)

The basic structure

The whole debate about recommended intakes is one thing, and of course Linus Pauling (and his 1971 paper) is at the center of the debate. Keeping an historical perspective is logical and useful. The fact that bowel tolerance varies in function of disease pertains to another logic, and to another section. Finally, the therapeutic uses are another section. No info will be suppressed in the process of structuring this article. Pierre-Alain Gouanvic 03:29, 19 November 2007 (CST)

...the 1974 paper. The reference has been included. Pierre-Alain Gouanvic 18:04, 19 November 2007 (CST)

The "Politics of Vitamin C" section

Was this a part of the original WP article? Because saying there is a conspiracy against Vitamin C seems awfully absurd (unless it actually is the case). Is it actually something that goes on? Also some things about the "Hypothesis" section seem equally dubious. --Robert W King 16:45, 19 November 2007 (CST)

It comes from WP. I agree. I'll work on that and will try to be constructive. Thanks for the input; I'll send you a notice when I it is done. Pierre-Alain Gouanvic 17:32, 19 November 2007 (CST)

A description of a nutrient includes its distribution in tissues and organs. This section will necessarily cover (part of) the debate on vitamin C requirements. Putting this in a separate "controversial" section would be biased.Pierre-Alain Gouanvic 21:08, 19 November 2007 (CST)

The "Vitamin C hypothesis" section

Many things in this section reflect a lack of understanding of who said what, etc. They will be moved in their respective sections on biosynthesis. Pierre-Alain Gouanvic 00:05, 20 November 2007 (CST)
