2.4 Aspartate
Aspartate is the most abundant excitatory neurotransmitter in the CNS. Like glycine, aspartate is primarily localized to the ventral spinal cord. Aspartate is a highly selective agonist for NMDAR-type glutamate receptors and does not activate AMPA-type glutamate receptors.
Herein, what is the role of aspartate?
Aspartate is believed to help your body promote a robust metabolism. From time to time it is used to treat depression and fatigue. This amino acid plays a key role in the citric acid cycle (also known as Krebs cycle), within which a number of other amino acids and biochemicals are formed.
Secondly, is aspartate positive or negative? The charged amino acids are easy to assign, they include two basic residues, lysine (Lys) and arginine (Arg) both having positive charge at neutral pH values, and two acidic, aspartate (Asp) and glutamate (Glu) both carrying negative charge at neutral pH. These residues are often found close to the surface of proteins.
Keeping this in view, what is glutamate and aspartate?
Glutamate and aspartate are nonessential amino acids that do not cross the blood—brain barrier and, therefore, are synthesized from glucose and a variety of other precursors. A large fraction of the glutamate released from nerve terminals probably is taken up into glial cells, where it is converted into glutamine.
What is the difference between aspartate and aspartic acid?
The main difference between aspartate and aspartic acid is that the aspartate is the ionic form of aspartic acid, which is an α-amino acid used in protein synthesis. Aspartate and aspartic acid are two forms of an amino acid which mainly serve as a building block for the synthesis of proteins.

Where is aspartate produced?
However, aspartic acid is found in: Animal sources: oysters, luncheon meats, sausage meat, wild game. Vegetable sources: sprouting seeds, oat flakes, avocado, asparagus, young sugarcane, and molasses from sugar beets. Dietary supplements, either as aspartic acid itself or salts (such as magnesium aspartate)
What is aspartate good for?
Uses. This medication is a mineral supplement used to prevent and treat low amounts of magnesium in the blood. Some brands are also used to treat symptoms of too much stomach acid such as stomach upset, heartburn, and acid indigestion.
Is aspartate the same as aspartame?
Is Zinc Aspartate different than Aspartame? Yes, Zinc Aspartate is a common, naturally occurring amino acid. Aspartame is an artificial sweetener found in products such as Equal. DripDrop ORS does not contain aspartame.
Is aspartate an amino acid?
Abstract. Aspartic acid (or aspartate) is a non-essential amino acid, meaning that it is readily and naturally synthesized by mammals. It is one of the 20 building-block amino acids of proteins, 3-letter code is ASP, one letter code is D. The DNA codons encoding aspartic acid are GAC and GAU.
Is aspartate an essential amino acid?
Essential amino acid. Six amino acids are non-essential (dispensable) in humans, meaning they can be synthesized in sufficient quantities in the body. These six are alanine, aspartic acid, asparagine, glutamic acid, serine, and selenocysteine (considered the 21st amino acid).
Is aspartate an excitatory neurotransmitter?
Significance statement: It has been proposed that the amino acid aspartate serves as a neurotransmitter. Although aspartate is a selective agonist for NMDA receptors, we find that glutamate alone fully accounts for neurotransmission at excitatory synapses in the hippocampus, excluding a role for aspartate.
Is aspartate negatively charged?
Substitutions: Aspartate (or Aspartic acid) is a negatively charged, polar amino acid.
What is the charge of aspartate?
Among the 20 common amino acids, five have a side chain which can be charged. At pH=7, two are negative charged: aspartic acid (Asp, D) and glutamic acid (Glu, E) (acidic side chains), and three are positive charged: lysine (Lys, K), arginine (Arg, R) and histidine (His, H) (basic side chains).
What are symptoms of high glutamate?
Excess brain glutamate is believed to cause numerous symptoms, including: hyperalgesia (pain amplification, a key feature of FMS) anxiety. restlessness. ADHD-like symptoms, such as inability to focus.
What is glutamate used for?
Glutamate is a powerful excitatory neurotransmitter that is released by nerve cells in the brain. It is responsible for sending signals between nerve cells, and under normal conditions it plays an important role in learning and memory.
Is aspartate polar or nonpolar?
The polar amino acids include: arginine, asparagine, aspartic acid (or aspartate), glutamine, glutamic acid (or glutamate), histidine, lysine, serine, and threonine. Polar side chains contain groups that are either charged at physiological pH or groups that are able to participate in hydrogen bonding.
Is magnesium aspartate safe?
Based on these margins of safety, the Panel concludes that the use of zinc and copper aspartate, as sources of zinc and copper at the proposed use levels, are not of safety concern but that the use of calcium, magnesium and potassium aspartate could be of safety concern because the margins of safety are considered too
Is aspartate inhibitory or excitatory?
Aspartate is a highly selective agonist for NMDAR-type glutamate receptors and does not activate AMPA-type glutamate receptors. Aspartate and glycine form an excitatory/inhibitory pair in the ventral spinal cord comparable to the excitatory/inhibitory pair formed by glutamate and GABA in the brain.
Is glutamate an essential amino acid?
Glutamate and glutamine: Nonessential or essential amino acid. Glutamine and glutamate are not considered essential amino acids but they play important roles in maintaining growth and health in both neonates and adults.
What are the neurotransmitters in the brain?
Neurotransmitters all serve a different purpose in the brain and body. Although there are several different minor and major neurotransmitters, we will focus on these major six: acetylcholine, dopamine, norepinephrine, serotonin, gamma-aminobutyric acid (more commonly referred to as GABA), and glutamate.
Is Glutamate the same as glutamic acid?
When glutamic acid, which is acidic, loses a hydrogen from its side chain, it becomes glutamate, with a side chain composed of CH2CH2COO. In the human body, glutamic acid almost always exists as glutamate, because conditions in the body favor the loss of the hydrogen atom from glutamic acid, explain Drs.
What is aspartate used for?
As a dietary supplement, aspartate is combined with minerals and is available as copper aspartate, iron aspartate, magnesium aspartate, manganese aspartate, potassium aspartate, and zinc aspartate. Aspartates are used to increase absorption of the minerals they are combined with and to enhance athletic performance.
Do amino acids contain phosphorus?
Amino acids are composed of an amino group, a carboxyl group, a lone hydrogen atom, and a side chain that varies between amino acids. Of the 20 major amino acids, none of them have a side chain that contains phosphorus. Only cysteine and methionine contain sulfur.
How is histidine positively charged?
Histidine, an essential amino acid, has as a positively charged imidazole functional group. The imidazole makes it a common participant in enzyme catalyzed reactions. The unprotonated imidazole is nucleophilic and can serve as a general base, while the protonated form can serve as a general acid.
