1-deoxysphingosine (m18:1)

1-Deoxysphingosine (m18:1(4E)) is an atypical sphingolipid that contains a double bond at the 4E native position and is formed when serine palmitoyltransferase condenses palmitoyl-CoA with alanine instead of serine during sphingolipid synthesis.1,2 Plasma levels of 1-deoxysphingosine (m18:1(4E)) are increased in patients with chronic idiopathic axonal neuropathy (CIAP) and diabetic distal symmetrical polyneuropathy (DSPN).3 |1.

1-Deoxysphingosine (m18:1(14Z)) is an unconventional sphingolipid featuring a (14Z) double bond at the n-4 position, synthesized when serine palmitoyltransferase combines palmitoyl-CoA with alanine, not serine, during sphingolipid production. Unlike typical sphingolipids, it lacks the essential C1-hydroxyl group for standard degradation but undergoes metabolism by cytochrome P450 (CYP) subfamilies CYP4A and CYP4F in MEF cells.
