Abstract
Summary
Dihydrosphingosine-4,5-3H, injected intracranially into nursing rats, was converted to sphingosine-3H, utilized for the synthesis of sphingolipids and dihydrosphingolipids, and catabolized with the incorporation of isotope into cholesterol and fatty acids from phospholipids and sphingolipids. Pathways of long-chain base metabolism are discussed.
