Description

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.
