• Application: Quinolinic acid is a pyridinedicarboxylic acid, presenting itself as either a white or light yellow powder. As an endogenous metabolite of tryptophan, it acts as a potent agonist at N-methyl-D-aspartate (NMDA) receptors, making it a significant excitotoxic compound within the central nervous system. Its interaction with amino acid receptors highlights its importance in understanding human neurodegenerative disorders, potentially linking the functions of kynurenic acid (KYNA) and quinolinic acid (QUIN) in the brain. Additionally, quinolinic acid's properties are utilized in the flotation process of hematite, where it facilitates the selective adsorption of amines onto the hematite surface, demonstrating its versatility beyond biological systems.
