I've moved this page from Betaine because Betaine as Trimethylglycine is far more common usage. This plural use is from the IUPAC [1], but if there's a better name, I won't object. Micha 08:40, 13 April 2006 (UTC)

And now we should move it back to betaine as trimethylglycine got it s own page... ChristianB 12:13, 25 September 2007 (UTC)

[edit] Pronunciation

According to Nickon, the correct pronunciation is "BEET-a ene", not BAY-tah ene or beh-TAYN. (Sorry, I don't know wiki-preferred orthographic symbols.) The term derives from the vegetable beets, not from the Greek letter beta (β). The trimethylglycine betaine was isolated from beets, hence the naming.

[edit] Usage

Cocamidopropyl betaine is the main ingrediant in Johnson's baby wash. This article should mention that. Mathiastck (talk) 20:47, 21 November 2007 (UTC)

[edit] Methyl Donor

The article states that it "is a methyl donor of increasing significance". Do we have references for this (not that I think we *need* references for this, just examples reactions where it can act as a methyl donor (is this original research? Probably not if the reactions themselves are referenced) I do know that in autism research, various methylation processes are a subject of great importance though. —Preceding unsigned comment added by 216.9.143.237 (talk) 16:28, 31 March 2008 (UTC)

[edit] Please add

How, and from what, are betaines usually made? I understand that they were formerly made from sugar beets, but now from petroleum. This should be made very clear in the article. Badagnani (talk) 01:16, 3 May 2008 (UTC)
