L-Theanine – Powder, 100 grams

L-theanine (γ-glutamylethylamide) is structurally related to glutamate, but its ethylamide substitution alters its interactions with glutamate receptor systems and transport mechanisms. Experimental investigations have demonstrated activity at NMDA receptor-associated signaling pathways, where L-theanine functions differently from glutamate despite structural similarity.

Studies have also reported modulation of AMPA receptor-associated processes and interactions with excitatory amino acid transporters (EAATs), making L-theanine a useful research tool for examining receptor-ligand specificity, glutamatergic signaling regulation, and amino acid structure-activity relationships.

L-theanine has been extensively investigated in studies examining electrophysiological activity patterns and neurotransmitter-associated signaling networks. Experimental research has reported effects on oscillatory neural activity, glutamatergic signaling, GABA-associated pathways, and monoaminergic neurotransmitter systems.

These characteristics have made L-theanine a valuable tool for investigations of electrophysiological regulation, neurotransmitter network dynamics, receptor-transporter interactions, and signal integration across multiple neurotransmitter systems.

L-theanine is highly water-soluble and is typically prepared in aqueous buffers, phosphate-buffered saline (PBS), or assay-specific media for biochemical and cell-based experiments.

Its favorable aqueous solubility facilitates preparation of defined-concentration stock solutions for receptor pharmacology studies, transporter investigations, concentration-response experiments, and other in vitro applications. The compound's stability and solubility characteristics make it particularly suitable for high-throughput experimental workflows and analytical research programs.
