N methyl D-aspartic acid (NMDA) is an amino acid derivative acting as a specific agonist at the NMDA receptor, and therefore mimics the action of the neurotransmitter glutamate on that receptor. In contrast to glutamate, NMDA binds to and regulates the NMDA receptor only, with no effect on other glutamate receptors.
N Methyl D-Aspartic acid is a little known receptor found in neurons and hormone regulating organs of the body. It has been deemed responsible for the incredible increase of hormonal output experienced during puberty, which results in rapid muscular and sexual development. This hormonal state is most desirable for building muscle mass and even useful in enhancing every aspect of sexual performance. This newly found receptor, when powerfully activated by amino acid based ingredient called NMDA, elicits profound elevations of circulating anabolic hormones.
1,NMDA can participate in hypothalmo-neurohypophysial system neuroendocrine regulatiion. NMDA with suitable concentration can obviously improve secretion of hypothalamus nerve cell SS and expression ofmRNA,improve Ca2+ level in cell and lower cAMP concentration.
2,NMDAplays an important roleintheneuroendocrine regulation.NMDAwith suitable concentrationcan affecttheorganismendocrine system, especiallypromotethe hormone significantly(GH)secretion of animalorganism toincreasebloodGHlevel.
3,NMDAcanaffectcell proliferation activity by inhibitingDNA synthesisofPC12 cells. So it can be used forthesynthesisofanticancer drugs.
4,NMDA withsuitable concentrationcan significantlypromotereleasing growth hormone in animaladenohypophysis,yellowpituitaryerythropoietin,gonadotropinand secretionofprolactin. It can be used asa newfeed additives with efficient growth promotion.
5,NMDAcan be used asa newfunctional food additives.
