Description_x000D_ General description_x000D_ N-Methyl-D-aspartic acid (NMDA) is an endogenously generated molecule in rat nervous system and endocrine glands. NMDA is present at low level (nmol/g) in the adenohypophysis, hypothalamus, brain, and testis. NMDA is derived from D-Asp by an S-adenosylmethionine-dependent enzyme also referred to as NMDA synthase._x000D_ Application_x000D_ N-Methyl-D-aspartic acid has been used to induce N-methyl-d-aspartic acid (NMDA) toxicity, cultures of retinal cells were supplemented with NMDA._x000D_ Packaging_x000D_ 1, 5 g in poly bottle_x000D_ 25, 100, 250 mg in poly bottle_x000D_ Biochem/physiol Actions_x000D_ Excitotoxic amino acid. Prototypic agonist at the NMDA-type glutamate receptor that regulates ion channels; important in long-term potentiation, ischemia, and epilepsy._x000D_ N-Methyl-D-aspartic acid (NMDA) plays a crucial role in release of luteinizing hormone and PRL (prolactin) in the pituitary gland and GnRH (gonadotropin releasing hormone) in the hypothalamus. It acts as a specific agonist for NMDA type glutamate receptors._x000D_ Features and Benefits_x000D_ This compound is also offered as part of Sigma′s Library of Pharmacologically Active Compounds (LOPAC®1280), a biologically annotated collection of high-quality, ready-to-screen compounds.
