How does Aspartate (redirected to Aspartic acid by Wikipedia) compare to Aspartame, the artificial sweetener? The reason I ask is, I found a protein drink that said it contained Aspartate. It had a warning on it for Phenolketonurics that it contains Phenolalynine. I have always associated that notice with Aspartame. Are Aspartate and Aspartame the same thing?

Hi, the answer should be pretty simple if you read the pages on aspartame, phenylalanine, and phenylketonuria. Aspartame is composed of aspartic acid and phenylalanine. I don't think the discussion page is meant for question-and-answer sessions though. However, if the pages I mentioned previously aren't enough to answer your question on their own, then perhaps they need to be updated. Eddietoran 20:25, 14 November 2007 (UTC)
I think this page should explain why our bodies use L-aspartic acid for proteinogenesis and D-aspartic acid as a neurotransmitter, and how it converts one to the other. Eddietoran 20:25, 14 November 2007 (UTC)
http://www.ncbi.nlm.nih.gov/sites/entrez?db=pubmed&list_uids=11093665&cmd=Retrieve&indexed=google states that "D-Aspartic acid can be enzymatically biotransformed with D-amino acid oxidase and aminotransferase to L-aspartic acid." Eddietoran 20:32, 14 November 2007 (UTC)
Should be aspartate
Aspartate (the deprotonated form) is the physiological form in vivo. Aspartic acid is not a physiological amino acid
Amino acid name
According to the 61st addition of the CRC (page C-112) handbook of Chemistry, Aspartic acid is also referred to as Aminosuccinic acid. This name should probably be added to the IUPAC name as well. I would add it myself, but it would probably be removed if no reason were given. I'm fairly confident that anyone in medicinal chemistry would agree that Aminosuccinic acid and Aspartic acid are two terms describing the same chemical.

- I would agree, and believe that one more name should be added - asparaginic acid with references to Medline Plus Encyclopedia. J.D. (talk) 20:21, 4 February 2010 (UTC)
IUPAC NAme and Structure
Relationship to Asparagus
Responding to the call for citation needed, need a biochem expert to weigh in. This may be a confusion due to similar name... Asparagusic acid is in asparagus along with other sulfur compounds, but Aspartic acid has no sulfur. "These compounds originate in the asparagus as asparagusic acid and its derivatives, as these are the only sulfur-containing compounds unique to asparagus." - from the Asparagus wiki-entry Hamilton Hall (talk) 16:36, 19 May 2011 (UTC)
- Asparagine was isolated from asparagus, and aspartic acid was derived from asparagine. I've modified the text and can embellish if you feel it is needed. I'll also take a look at the Asparagus article and see what might be needed.Novangelis (talk) 04:55, 26 July 2011 (UTC)
Why would aspartic acid be sold as a dietary supplement?
This is a request for information that I think should be included in the article. I know other amino acids, e.g., lysine, tryptophane, are sold for specific purposes. What claims are made for aspartic acid and do they have any validity? I'm skeptical about the utility of a non-essential amino acid related to asparagine. Hopefully this request will not be seen as general discussion but petition for article expansion. Thank you all for all that you do. Acarolinensis (talk) 06:33, 8 October 2013 (UTC)
After 3 clinical studies it's not called skepticism any more :D
I don't know how this went unnoticed, but aren't the diagrams wrong? Amine group should be closer to the carboxyl group. See https://en.wikipedia.org/wiki/File:Amino_Acids.svg for comparison. Aqua3993 (talk) 22:54, 12 February 2015 (UTC)
- Well, there is no stereochemistry noted so I am not sure if it is a possible notation or not. Just to be sure I've checked the Merck index and picked proper image of L-aspartic acid from commons. But then there is mine question: is the ball-and-stick model correct? --Faskal (talk) 09:37, 2 May 2015 (UTC)

Hi fellow wiki editors, I’m a 3rd year Physiological sciences major at UCLA and I’m going to be editing and adding to this page. I’m new to Wiki editing so if I make a mistake or you as fellow editors see an area that needs additional information and/ or correction, feel free to let me know! -Darien A.
Introduction: • Edit and clean up information • Make the introduction flow better and present background in a clear and concise way • Diferentiate between aspartate and aspartic acid o Which form is used in the body o Its biological relevance • Mention that our bodies use the D-aspartate confirmation
Discovery: • Elaborate and verify current posted information o How it was discovered o What experiments were used in its discovery Structure: • Create or locate a useable image demonstrating proper stereochemistry
Metabolism: • Identify other sources of production • Fact check currently listed sources • Write out proper equation (current one does not even include a yield sign)
Other biochemical roles: • Fact check current information (lacks citations) • Expand section • Elaborate • Write equations of reactions its involved in
Neurotransmitter: • Elaborate and expand • Possibly combine this section with another appropriate section
Application and market: • D-aspartic acid is currently sold by supplement companies as a “testosterone booster” so I’d like to mention that after further research
