How about Organic chemistry Fatty acid chemistry

Not all esters are organic--Wikipedia gives the example of a phosphoric acid ester. Not every ester can be derived from a fatty acid. Peter Lyall Easthope 23:24, 24 November 2008 (UTC)

What is a half-ester?

David E. Volk 14:40, 25 November 2008 (UTC)

David, that is precisely the question which turned up here and prompted me to insert the term in the Related Articles. As far as I can tell it is an ester according to my definition where R2 is as small as possible without being H; ie. R2=C00H. Reference [[1]].

It would seem to be a shorthand colloquism for a half esterified dicarboxylic acid from the reference listed above. I am not sure that it is a "real" chemical term widely used. David E. Volk 00:42, 28 November 2008 (UTC)
