Daptomycin.svg
Hi, I noticed you changed the image on the Daptomycin page, citing the reason that it was incorrect. Would you mind telling me where the mistake is, as I can then change the SVG accordingly, as the GIF there now is very low-resolution. I've had a look at this site, this site and this image, and I can't immediately see the difference, except some of them show COOH groups explicitly and some just label them "COOH".

Hello,

There were a few problems with the structure, actually. As I no longer have the old image in front of me, I can only tell you that there were 3 carbonyl groups completely missing, as well as a nitrogen in an amide bond. (The fatty acid tail was attached via a C-C bond, and should have been through an amide linkage.) If you can compare the structure I have posted with the last one, you will clearly see the differences. I hope this helps. If you need additional clarification, please let me know!

Cheers!


 * Would you mind haveing a quick check of image:Daptomycin.svg? I used pubChem's inchi string and then edited in Inkscape (such as making everything nice paths and making COOH groups, as I think that is clearer than having the actual structure there). Thanks for being so on-the-ball! Not many people would notice that mistake! Inductiveload (talk) 00:51, 17 June 2008 (UTC)
