Page moved

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)[reply]

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

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.

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) Alkyl betaines are, being amphoteric surfactants, often used in shower creams. —Preceding unsigned comment added by Bubicicica (talkcontribs) 21:59, 22 June 2008 (UTC)[reply]

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)[reply]

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)[reply]
