Abstract
The occurrence of an unusual fatty acid, iso 24:0 (22-methyltricosanoi c acid), has been shown to be present in the sphingomyelin from rat li ver by gas liquid chromatography-mass spectrometry. The fatty acid is also present in the sphingomyelin of rat tissues tested, except for br ain and fetal serum. Supplementation of diets with L-valine elevated t he content of iso 24:0 in rat liver, heart, and kidney sphingomyelin. The fatty acid appears to be present in sphingomyelin of the sera of m ice, dogs, and cats, but not humans. (C) 1998 Elsevier Science Inc.
