CPT1A and inherited fatty acid metabolism disorder: Carnitine palmitoyltransferase 1 A (CPT1A) is in the outer mitochondrial membrane by which long‐chain fatty acyl‐CoA converts to L‐palmitoylcarnitine, as a key step in the uptake of long‐chain fatty acids into mitochondria for β‐oxidative metabolism.[45] We induced CPT1A dysfunction as a model of fatty acid metabolism disorder in which the palmitoylated modifier PA should be increased in astrocytes.
