NAA is the second-most-concentrated molecule in the brain after the amino acid glutamate. It is detected in the adult brain in neurons oligodendrocytes and myelin and is synthesized in the mitochondria from the amino acid aspartic acid and acetyl-coenzyme A. Magnetic resonance spectroscopy (MRS) provides useful information regarding metabolic composition in the tissues, and advanced spectroscopic methods are used to quantify markers of tumor membrane turnover and proliferation (e.g., choline (Cho)), energy homoeostasis (e.g., creatine (Cr)), intact glioneuronal structures (e.g., N-acetylaspartate (NAA)), and necrosis Author: B C Hamsini, Bhavana Nagabhushana Reddy, Sankar Neelakantan, Sunitha Palasamudram Kumaran.

N-acetylaspartate, or NAA, is the acetylated form of the amino acid aspartate, and it is present exclusively in the nervous system. Indeed, NAA is one of the most highly concentrated chemicals N-Acetylaspartate book in the brain of humans and animals, and yet the functions served by this brain-specific metabolite remain elusive, and controversial.
N-Acetylaspartic Acid. N-acetylaspartate (NAA) is an amino acid derivative, formed by the acetylation of l-aspartic acid, present in very high concentrations (up to 10mM) in mammalian brain and localized predominantly in neurons (Tallan et.
N-Acetylaspartate, or NAA, is one of the most concentrated chemicals in the human brain, but its functions are still controversial. Because of its high concentration, NAA produces a very strong signal in magnetic resonance spectrograms of the brain.5/5(2).
N-acetylaspartate, or NAA, is the acetylated form of the amino N-Acetylaspartate book aspartate, and it is present exclusively in the nervous system. Indeed, NAA is one of the most highly concentrated chemicals found in the brain of humans and animals, and yet the functions served by this brain-specific metabolite remain elusive, and controversial.
Despite the uncertainties. N-Acetylaspartate (NAA, Figure 1) is an enigmatic molecule present at exceptionally high concentrations in the brain (Tallan et al., ; Tallan, ). The levels found in various areas of the brain can reach 10mM or greater (Bluml, ; Miyake et al., ; Pan and Takahashi, ), making it one of the most concentrated molecules in the Cited by: N-acetylaspartate in the vertebrate brain: metabolism and function.

[email protected] N-Acetyl-L-aspartate (NAA) is an amino acid that is present in the vertebrate by: N-Acetylaspartate, or NAA, is one of the most concentrated chemicals in the human brain, but its functions are still controversial.
Because of its high concentration, NAA produces a very strong signal in magnetic resonance spectrograms of the brain. This signal is reduced in many different brain disorders and diseases, making NAA a valuable 5/5(2).

N-acetylaspartate (NAA) is one of the more important compounds assessed on MR spectroscopy, and resonates at ppm chemical shift (its concentration in healthy adults is mM) The synthesis of NAA, adenosine diphosphate-dependent, occurs in the neuronal mitochondria NAA is the acetylated form of the amino acid, aspartate, which is found in high concentrations.
Proton magnetic resonance spectroscopy ([sup.1]H MRS) is a useful tool that detects brain metabolites such as NAA (N-acetylaspartate), a marker for neuronal integrity or neuronal-glial homeostasis; Glx (GABA, glutamine, and glutamate); Cho (choline containing compounds), a measure of cellular density; Cr (creatine plus phosphocreatine), a marker of cellular energy.
N-acetylaspartate, or NAA, is the acetylated form of the amino acid aspartate, and it is present exclusively in the nervous system. Indeed, NAA is one of. To evaluate the contribution of cellular dysfunction and neuronal loss to brain N‐acetylaspartate (NAA) depletion, NAA was measured in brain tissue.

NAA is used in nonsurgical analyses of nerve cell dysfunction, and it is implicated in a disorder known as Canavan's disease.
N-acetylaspartate (NAA) is a small amino acid synthesized by neuronal mitochondria, which can be released in the extracellular space after reperfusion in animal models of brain ischemia. BACKGROUND AND PURPOSE: The most abundant metabolite visible by proton magnetic resonance spectroscopy (MRS) in human brain is N-acetylaspartate (NAA), which is often used as a marker of viable neurons.
NAA is anecdotally reported to be elevated in children with sickle cell disease (SCD), even though patients can have brain injury or atrophy. We Cited by: N-Acetylaspartate is the second most abundant amino acid in the central nervous system and is reliably measured by proton magnetic resonance spectroscopy (1H-MRS).
N-Acetylaspartate is formed in mitochondria from acetyl co-enzyme A and aspartate by the membrane-bound enzyme L-aspartate N-acetyltransferase, an enzyme selectively found in brain (12).
