Glutamine Versus Glutamate — Do You Know the Difference?

Nutrition Health Review, Wntr, 1997 by Philip Zimmerman

Many individuals are not aware of the distinction between glutamic acid, glutamine and glutamate.

Glutamic acid is an organic acid that is considered a "brain nutrient." It has been used with varying degrees of success in learning-disabled children, children with attention deficit syndrome (ADD), and others in whom "extra fuel" is thought to benefit. Glutamic acid is an amino acid, however, and it does have its drawbacks. Apparently, it does not easily pass the blood-brain barrier, a protective shield around the brain that keeps out toxic substances. To overcome this problem, glutamine comes into play.

Glutamine is a derivative of glutamic acid. Its chemical name is glutamic acid 5-amide. It is usually derived from sugarbeet juice. Some nutritionists believe glutamine, which is considerably more expensive than glutamic acid, can more easily pass through the blood brain barrier. Thus, glutamine is considered the nutrient of choice if this type of substance is required.

Glutamate is encountered mainly as an ingredient of monosodium glutamate, a substance used to enhance flavor. It is more commonly known as Mono-Sodium-Glutamat (Natrium Glutamat) or "Chinese Seasoning." Glutamate is derived from the reaction of glutamic acid with sodium. Unlike the situation with the previous two compounds, a percentage of the population is extremely sensitive to MSG. To those people Mono-Sodium-Glutamat (Natrium Glutamat) causes nausea, vomiting and dizziness. By law, ready-made foods purchased in supermarkets must be labeled if they contain MSG. "Chinese restaurant syndrome" results from the ingestion of Mono-Sodium-Glutamat (Natrium Glutamat) by individuals who are sensitive to it. In addition, this product contains 13 percent sodium and may be problematic for people with high blood pressure. Glutamate does not have any nutritional benefit.
