Application


  • Metabolomics Analysis Identifies Differential Metabolites as Biomarkers for Acute Myocardial Infarction.: Research identifies key metabolites, including L-Aspartic acid, involved in the metabolic pathways affected during acute myocardial infarction. This study enhances the understanding of biochemical changes during heart attacks, potentially leading to better diagnostic markers (Zhou et al., 2024).

Biochem/physiol Actions

L-Aspartic acid is a natural proteinogenic amino acid that may be used in the formulation of cell culture media and in protein and polypeptide synthesis systems and procedures. L-Aspartic acid, an NMDA receptor agonist and non-specific glutamate receptor agonist, is used to differentiate and study the mechanisms of NMDA receptors.
Principal neurotransmitter for fast synaptic excitation.
