Stearoyl-L-carnitine chloride is an endogenous long-chain acylcarnitine. Stearoyl-L-carnitine chloride is a less potent inhibitor of GlyT2. Stearoyl-L-carnitine chloride inhibits glycine responses by 16.8% at concentrations up 3 μM[1][2].

In Vitro	Stearoyl-L-carnitine (0.01-10 μM) inhibits glycine (30 μM) transports by 16.8% at concentrations up 3 μM in Xenopus laevis oocytes[2]. Stearoyl-L-carnitine (500 μM; 30 min) inhibits Na+-dependent [3H]carnitine (20 nM) uptake by ~50% in HPCT cells[3].
In Vivo	Stearoyl-L-carnitine is significantly decreased in Alzheimer's disease (AD), mild cognitive impairment (MCI) and subjective memory complaint (SMC)[1].
