Can somebody please explain why is it so evidently that the need for this amino-acid is restricted to children ? Same for histidine. Thanks.

[edit] IUPAC Name

I have reverted back to the IUPAC name I added because I got the name from an IUPAC publication. I think these should be the correct names for all of the amino acids since they are from IUPAC. Borb 21:54, 10 August 2005 (UTC)

[edit] Sexual uses

I had to delete that i just can't stand pseudoscience. Boris 13:48, 19 December 2005 (UTC)

[edit] Other uses

Arginine is widely used in sports supplementation. Adding some information on this subject should be relevant. I have started to take l'arginine in hopes of increasing my sexual stamina and for ED. I will keep you posted of the results. i'm not convinced yet.

[edit] Other sources

etc.? Could someone add some non-meat sources or a link to where one can find such information --Mig77 13:14, 17 March 2006 (UTC)

[edit] Protonation state

The protonation state shown is impossible. Any conditions acidic enough to protonate the carboxyl would also protonate the amine and guanido... —The preceding unsigned comment was added by 134.121.43.59 (talk • contribs) .

Excellent point, but the same problem affects the images of all the amino acids, not just arginine. I'll bring it up at Wikipedia talk:WikiProject Chemistry. —Keenan Pepper 22:27, 12 August 2006 (UTC)
