L-Palmitoylcarnitine 是一种长链酰基肉碱和脂肪酸代谢产物，在缺血期间积聚于肌膜并扰乱膜脂环境。L-Palmitoylcarnitine 通过与 Kir6.2 的相互作用抑制 KATP 通道活性，而不影响单通道电导。

Human Endogenous Metabolite
|
L-Palmitoylcarnitine (1 µM) inhibits K
ATP
channel activity, without affecting the single channel conductance, through interaction with Kir6.2. L-Palmitoylcarnitine simultaneously enhances the ATP sensitivity of the channel (IC
50
fell from 62 to 30 µM).
Modulation of the membrane lipid environment caused by L-Palmitoylcarnitine alters the K
ATP
channel function mainly through the interaction with endogenous PI cascade, especially PIP2.
