General description
L-Glutamic acid is an amino acid mainly used as a flavor enhancer in the food industry. It occurs naturally in kelp. L-Glutamic acid is said to impart umami-like taste in ready-to-drink (RTD) green tea.
Biochem/physiol Actions
An excitatory amino acid neurotransmitter that is an agonist at all subtypes of glutamate receptors (metabotropic, kainate, NMDA, and AMPA).

The molecular basis for the known intramembrane receptor/receptor interactions among G protein-coupled receptors was postulated to be heteromerization based on receptor subtype-specific interactions between different types of receptor homomers.

Locomotion is controlled by spinal networks that generate rhythm and coordinate left-right and flexor-extensor patterning.
