L-(+)-Glutamic acid hydrochloride Chemical Properties, Uses, Production

Chemical Properties

white crystals or fine crystalline powder

Uses

Glutamic Acid Hydrochloride is a flavoring, salt substitute that is soluble in water and very slightly soluble in alcohol and ether. It is obtained by chemical synthesis.

Uses

L-Glutamic acid hydrochloride is used as a digestive aid. It is used in cell culture as a component of MEM non-essential amino acids solution. It has been used as a nitrogen source in the culture of Aspergillus fumigatus NRRL 2436 for fumagillin production.

General Description

L-glutamate is the major excitatory neurotransmitter in mammalian central nervous system (CNS). It interacts with membrane bound glutamate receptors.

Biochem/physiol Actions

L-glutamate plays key roles in development, learning, memory, plasticity and cognition. It plays crucial role in the pathogenesis of neuropathological diseases such as epilepsy, schizophrenia, stroke, ischemia, ALS (amyotrophic lateral sclerosis), Huntington′s disease and Parkinson′s disease. Glutamate is also responsible for the activation of long-term potentiation (LTP) and long-term depression (LTD). Induction of glutamate receptors plays a key role in the pathophysiology of migraine.
