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.

The aim of this study was to determine if the potassium aspartate and magnesium (PAM) prevent reperfusion-induced ventricular arrhythmias (RIVA) in ischemia-reperfusion (IR) rabbit heart. Thirty rabbits were randomly divided into control, ischemia and PAM groups. Arterially-perfused rabbit left ventricular
