L-谷氨酸是哺乳动物中枢神经系统（CNS）中主要的兴奋性神经递质。它能与膜结合型谷氨酸受体发生相互作用。 L-谷氨酸盐酸盐已被用作一种营养添加剂，用于研究增加溶解无机氮（DIN）对限制氮源的源头森林溪流中溶解有机氮（DON）和溶解有机碳（DOC）吸收的影响 L-glutamate is the major excitatory neurotransmitter in mammalian central nervous system (CNS). It interacts with membrane bound glutamate receptors L-Glutamic acid hydrochloride has been used as a nutrient additive to study the effect of increased dissolved inorganic nitrogen (DIN) on the uptake of dissolved organic nitrogen (DON) and dissolved organic carbon (DOC), in a nitrogen-limited headwater forest stream
