WebSphingosine 1-phosphate is dephosphorylated or cleaved to ethanolamine phosphate and trans-2-hexadecenal (from sphingosine) (Fig. 12) or palmitaldehyde (from sphin-ganine) by a pyridoxal 5′-phosphate-dependent lyase [9]. The aldehyde intermediate is oxidized to fatty acids, or reduced to the alcohol and incorporated into alkyl ether lipids.
