General description
肉豆蔻酰基-L-肉碱属于酰基-L-肉碱类化合物，其是源自氨基酸和脂肪酸分解的L-肉碱的乙酰化形式。据报道，这些化合物可用作肉毒碱缺乏诊断中的生物标志物。
Application
肉豆蔻酰基-L-肉碱可用作分析标准品，通过使用与三重四极杆-LC MS/MS偶联的高效液相色谱法测定玉米植物中分析物的含量。肉碱的外源应用刺激了脂肪酸向线粒体的运输，并研究了在正常和冷冻条件下生长的玉米叶片中肉碱对细胞质、线粒体基质和线粒体呼吸之间脂质运输的可能效应作用。
可以用作以下过程中的分析标准品：
可以用作以下过程中的分析标准品：
- 使用高效液相色谱串联质谱法（HPLC-MS/MS）分离和鉴别人血浆样品中未衍生化的肉豆蔻酰基-L-肉碱。
- 使用高效液相色谱（HPLC）结合电喷雾电离-串联质谱法（ESI-MS/MS）测定干血样中的分析物。

Electrospray ionization-tandem mass spectrometry (ESI-MS/MS) is increasingly used in newborn screening programs. Acylcarnitine profiles from dried blood spots (DBS) are used to detect fatty acid oxidation disorders, carnitine cycle disorders, and organic acidurias. Stored dried blood is also a valuable
