As a free amino acid form, it maintains its unbound state, differing from its HCl or FAA counterparts in solubility and absorption properties. This compound primarily interacts with GABA_B receptors, influencing neurotransmitter signaling pathways. It undergoes hepatic metabolism via deamination and conjugation, with primary excretion through renal clearance.
