Abstract

Background: Myristate is a novel potential substrate for sphingoid base synthesis. Results: Myocardial sphingoid base synthesis utilizes myristate; these sphingolipids are functionally non-redundant with canonical sphingoid bases. Conclusion: d16:0 and d16:1 sphingolipids constitute an appreciable proportion of cardiac dihydrosphingosine and dihydroceramide, with distinct biological roles. Significance: This pool of sphingolipids may play a heretofore unsuspected role in myocardial pathology or protection.
