This substance is the target of transporters coded for by the SLC1A family of genes, known as EAATs. Though not kainic acid, this endogenous chemical binds to KARs, and its buildup in extracellular space causes internal calcium 2+ buildup and cell death. Its binding to another protein channel causes EPSP depolarization and induces long-term potentiation. Its N-acetyl form regulates carbamoyl phosphate synthase and, indirectly, the urea cycle, while that aforementioned channel, antagonized by the drug PCP, is the NMDA receptor. A precursor of it precedes succinyl CoA in the Krebs cycle; that precursor is an alpha keto acid. Its replacement by valine at position 6 on the beta-globin chain causes sickle cell anemia. For 10 points, name this excitatory neurotransmitter and amino acid whose ionic form is a flavor enhancer.
