In metabolism

Glutamate is a key molecule in cellular metabolism. In humans, dietary proteins are broken down by digestion into amino acids, which serves as metabolic fuel for other functional roles in the body. A key process in amino acid degradation is transamination, in which the amino group of an amino acid is transferred to an α-ketoacid, typically catalysed by a transaminase.

R1-amino acid + R2-α-ketoacid R1-α-ketoacid + R2-amino acid

A very common α-ketoacid is α-ketoglutarate, an intermediate in the citric acid cycle. When α-ketoglutarate undergoes transamination, it always results in glutamate being formed as the corresponding amino acid product. The resulting α-ketoacid product is often a useful one as well, which can contribute as fuel or as a substrate for further metabolism processes. Examples are as follows: Overview of the citric acid cycle The citric acid cycle (also known as the tricarboxylic acid cycle, the TCA cycle, or the Krebs cycle, after Hans Adolf Krebs who identified the cycle) is a series of chemical reactions of central importance in all living cells that use oxygen as part...

Ammonia (as ammonium) is then excreted predominantly as urea, synthesised in the liver. Transamination can thus be linked to deamination, effectively allowing nitrogen from the amine groups of amino acids to be removed, via glutamate as an intermediate, and finally excreted from the body in the form of urea.

As a neurotransmitter

Glutamate is the most abundant fast excitatory neurotransmitter in the mammalian nervous system. At chemical synapses, glutamate is stored in vesicles. Nerve impulses trigger release of glutamate from the pre-synaptic cell. In the opposing post-synaptic cell, glutamate receptors, such as the NMDA receptor, bind glutamate and are activated. Because of its role in synaptic plasticity, it is believed that glutamic acid is involved in cognitive functions like learning and memory in the brain.

Glutamate transporters[3] are found in neuronal and glial membranes. They rapidly remove glutamate from the extracellular space. In brain injury or disease, they can work in reverse and excess glutamate can accumulate outside cells. This process causes calcium ions to enter cells via NMDA receptor channels, leading to neuronal damage and eventual cell death, and is called excitotoxicity. The mechanisms of cell death include: Glutamate transporters exist in the membranes of neurons and glial cells to remove excess amounts of the amino acid neurotransmitters glutamate and aspartate from the synapse. ...

Glutamic acid has been implicated in epileptic seizures. Microinjection of glutamic acid into neurons produces spontaneous depolarisations around one second apart, and this firing pattern is similar to what is known as paroxysmal depolarizing shift in epileptic attacks. This change in the resting membrane potential at seizure foci could cause spontaneous opening of voltage activated calcium channels, leading to glutamic acid release and further depolarization. This article is about the medical term, epileptic seizure, as distinct from a non-epileptic seizure. ... In neuroscience, depolarization refers to the event a neuron undergoes when its membrane potential grows more positive with respect to the extracellular solution. ...

Experimental techniques to detect glutamate in intact cells include using a genetically-engineered nanosensor[2]. The sensor is a fusion of a glutamate-binding protein and two fluorescent proteins. When glutamate binds, the fluorescence of the sensor under ultraviolet light changes by resonance between the two fluorophores. Introduction of the nanosensor into cells enables optical detection of the glutamate concentration. Synthetic analogs of glutamic acid that can be activated by ultraviolet light have also been described[6]. This method of rapidly uncaging by photostimulation is useful for mapping the connections between neurons, and understanding synapse function. Nanosensors are a technology that may exist in the future. ... “UV” redirects here. ...

In brain nonsynaptic glutamatergic signaling circuits

Extracellular glutamate in Drosophila brains has been found to regulate postsynaptic glutamate receptor clustering, via a process involving receptor desensitization[7]. A gene expressed in glial cells actively transports glutamate into the extracellular space[7], while in the nucleus accumbens stimulating group II metabotropic glutamate receptors was found to reduce extracellular glutamate levels[8]. This raises the possibility that this extracellular glutamate plays an "endocrine-like" role as part of a larger homeostatic system. This article or section does not cite its references or sources. ... In cell biology, molecular biology and related fields, the word extracellular (or sometimes extracellular space) means outside the cell. This space is usually taken to be outside the plasma membranes, and occupied by fluid. ...

Glu also serves as the precursor for the synthesis of the inhibitory GABA in GABA-ergic neurons.

Sources and absorption

Glutamic acid is present in a wide variety of foods and is responsible for one of the five basic tastes of the human sense of taste (umami), especially in its physiological form, the sodium salt of glutamate in a neutral pH. Ninety-five percent of the dietary glutamate is metabolized by intestinal cells in a first pass [5]. The basic tastes are the commonly recognized types of taste sensed by humans. ...

Human taste sensory organs, called taste buds or gustatory calyculi, and concentrated on the upper surface of the tongue, appear to be receptive to relatively few chemical species as tastes. ...

Overall, glutamic acid is the single largest contributor to intestinal energy. As a source for umami, the sodium salt of glutamic acid, monosodium glutamate (MSG) is used as a food additive to enhance the flavor of foods, although an identical effect can be achieved by mixing and cooking together different ingredients rich in this amino acid and other umami substances as well.

China-based Fufeng Group Limited is the largest producer of Glutamic Acid in the world, with capacity increasing to 300,000 tons at the end of 2006 from 180,000 tons during 2006, putting them at 25 - 30% of the chinese market. Meihua is the second largest Chinese producer. Together, the top five producers have roughly 50% share in China. Chinese demand is roughly 1.1 million tons per year, while global demand, including China, is 1.7 million tons per year.


The drug phencyclidine (more commonly known as PCP) antagonizes glutamic acid non-competitively at the NMDA receptor. For the same reasons, sub-anaesthetic doses of Ketamine have strong dissociative and hallucinogenic effects. Glutamate does not easily pass the blood brain barrier, but: "glutamate flux from plasma into brain is mediated by a high affinity transport system at the Blood-Brain Barrier" [1]. It can also be converted into glutamine. Phencyclidine (a contraction of the chemical name phenylcyclohexylpiperidine), abbreviated PCP, is a dissociative drug formerly used as an anesthetic agent, exhibiting hallucinogenic and neurotoxic effects. ...

Glutamate transport and supply are obvious targets for the treatment of epilepsy, therefore. In particular Glutamate Restriction Diets are now claiming success anecdotally, by limiting or eliminating intake of wheat, peanut, soy and bean.

High glutamate diets, that is, with brewer's yeast, have also been successful in treating schizophrenia. There is, however, no published data to this effect.
