I'm not sure what the controversy is here (appearantly 'processed' vs. 'natural glutamic acid ?), but this paper is chock full of chemical and biochemical errors: I landed on this site looking for biochem data.
The first sentence of objects that ALWAYS contain MSG : sorry but there is NO SODIUM in glutamine/glutamic acid. Glutamine is an amino acid necessary for your body to make proteins. It is a neccesity for survival, and is even supplemented by most atheletes. It has nothing to do with the element sodium.
There is NEVER a difference in the structure or function of a biochemical regardless of how it is "made" - that is its identity - just like your name is Julie regardless of who calls you by that name. There MAY be a difference in impurities, but now we are talking about 0.02% from a synthetic product, and there are many more impurities ( % weight )in "natural" products.
L-forms of amino acids (or any chemical) cannot "make" D-forms of that amino acid, nor can they be converted to it. ANY L-molecule must be completely dismanteled and then "put back together" in D-form. IT is ALWAYS easier to make the desired form (D or L)from scratch. This means that usually (not always) the D-form is passed from the body, as there is no receptor for it. You alude to this in your last few sentences. You also state that ALL D/L forms are manufactured (and used in food?)in a 50-50 ratio. Fact: Stereo Isomers almost never form anywhere close to 50-50. One form (D or L), is always preferable(easier to form) based on the process used. The only amino acid that I know that has a roughly equall D analougue, is phenylalanine. but it has a purpose. It retards adult onset diabetes, and controls blood sugar levels. I didnt read the whole article, and again I'm guessing at what the issue is. I assume its "natural" vs. "processed" food. If thats the case, it ALWAYS depends on the sources. For example, 'natural' whole rice is better than 'processed' white. Unless of coarse, the 'natural product was grown in a rice paddy that doubled as a sewer. In that case, pass the white. Hope you study a little more, before you stop eating all together.
