General description
L-aspartic acid is a non-essential amino acid.
Application
L-Aspartic acid potassium salt has been used:
- to prepare perforated patch-clamp intracellular solution
- in serum glutamate–oxaloacetate transaminase (SGOT) assay
- as a component in an internal solution (IS) for mitoflash assay to detect mitochondrial flashes in permeabilized cells
Biochem/physiol Actions
L-Aspartic acid is an endogenous N-methyl-D-aspartate (NMDA) receptor agonist.
Potassium aspartate is capable of preventing ventricular arrhythmia in ischemic rabbit heart by decreasing transmural repolarization dispersion (TDR).
Principal neurotransmitter for fast synaptic excitation.
