Application

L-Theanine USP reference standard suitable for use in specified USP compendial quality tests and assays.

Biochem/physiol Actions

Theanine is able to bind to AMPA, kainite, and NMDA glycine receptors in rat cortical neurons but with less affinity than glutamic acid. It has been studied as a glutamate transport inhibitor, preventing glutamate uptake by M5076 ovarian sarcoma-bearing mouse cells and increasing the effect of doxorubicin on tumor growth in M5076 mice.

Other Notes

Theanine is an amino acid analog of glutamine, found in green tea.
Sales restrictions may apply.
