Acid sphingomyelinase (Asm) and acid ceramidase (Ac) are parts of the sphingolipid metabolism. Asm hydrolyzes sphingomyelin to ceramide. which is further metabolized to sphingosine by Ac. Ceramide generates ceramide-enriched platforms that are involved in receptor clustering within cellular membranes. https://www.alarecre.com/NHL-Dallas-Stars-Black-Background-iPhone-13-Pro-Max-MagSafe-Case-p96318/
