Title: amino acid
Post by: vtbui on May 24, 2006, 04:05:55 AM
How to synthesize an amino acid (alanine) with just water, H2, CH4, NH3, and light? Can you give me any suggestion on how to start the reaction/mechanism?  Thank you

Search internet on prebiotic synthesis

I check this website, but it does not explain how the mechanism works?  I have also check alot of website with Miller experiments on google. Do you have any idea how to begin a reaction?  Thank You

Most of reaction have a radical mechanism. It is very difficult to predict such a mechanism. In my links you can find a sketched mechanism to obtain glycine and photo of apparatus for a prebiotic synthesis. More data are in Miller papers.
Alanine is hypothetically synthesized through the glycine.
