L-carnitine 是一种人内源性分子，在人体内以蛋氨酸和赖氨酸为底物进行生物合成，并参与脂肪酸代谢。L-Carnitine 将长链脂肪酰辅酶A转运到线粒体。L-Carnitine 能够改善许多先天性代谢错误的代谢失衡。

L(-)-Carnitine is an amino acid derivative. L(-)-Carnitine facilitates long-chain fatty acid entry into mitochondria, delivering substrate for oxidation and subsequent energy production. Fatty acids are utilized as an energy substrate in all tissues except the brain.
