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] Vegetarian vs Vegetable sources and Chocolate?
It seems to me that milk and chocolate are vegetarian. Now if we are trying to say vegetable sources, then milk is definitely not one, but what about chocolate? Chocolate does not necessarily include milk. In fact, I have in my hands right now a Trader Joe's organic dark chocolate 73% super dark bar which does not include any animal product. I can find no actual measurements of chocolate's arginine or lysine content. So does anyone have a source to back up chocolate being on this page? Renduy 17:38, 15 November 2007 (UTC)
[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)
fair enough but the article does state it may release prolactin. and that it is a precursor to NO. consider what viagra does wrt NO, and the role played by NO. also there has been newsreports of people who drank an energy drink (boost?) with ~1g arginine having a severe erection, and even resorting to surgery to aleviate the ahem, erection. 220.101.168.96 01:12, 18 June 2007 (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.
Hey,try taking some Citrulline in combination with the Arginine.The two aminos will work together great.
About the Prolactin issue,it should also state that SOME (some being the keyword here) bodybuilders stay away from free-form Arginine supplementation,on the other hand an entire supplement category exists around free-form Arginine.This category is called N.O supplementation.It usually consists of a pre-workout powder such as BSN N.O Xplode which was the product that started the entire trend of Nitric Oxide supplements.These powders usually contain some advanced form of Arginine (Arginine AKG),a few other aminos that work in syergy with Arginine such as Orthinine & Citrulline and some type of stimulant,usually Caffeine.
These supplements are very popular in the bodybuilding world due to the muscle volumizing effects they have when taken before a workout.Now regarding the Prolactin issue,I think many either don't know or just don't care as they use the supplements strictly for the cosmetic "pump" it gives them.
P.S I am very new to this Wikipedia thing,if I did not enter what I wrote in the right place I apologize.
[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)
Why does it occur only in Canadian bacon - are pigs everywhere else arginine-free? —The preceding unsigned comment was added by 210.18.195.2 (talk) 07:19, August 23, 2007 (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)
- Just to let you know, the chemical strucutre you have listed for this molecule is wrong and you are not showing the charges that are located on two of the nitrogens. The group double bonded to the last carbon should be NH2 with a + charge (you have only NH) and also the amino group (-NH3) on the alpha carbon (the carbon next the carboxyl group) should have a + charge on it. —Preceding unsigned comment added by 68.226.5.181 (talk) 20:36, August 28, 2007 (UTC)
I believe it would be better to show arginine with the side chain charged. Truckhence 19:39, 2 November 2007 (UTC)
[edit] Argenine for energy and stomach
I'm taking L-arginine and it's a miracle supplement. I've sufferered from severe bloating and stomach pain for years and this helps that alot and gives me a lot of energy. Maybe it helps b/c it helps improve blood flow to my stomach and liver. It's worked miracles for me and I will keep taking it. —Preceding unsigned comment added by Interestedperson (talk • contribs) 17:42, 24 February 2008 (UTC)
