ChEBI: N-hexacosanoylsphingosine-1-phosphocholine is a sphingomyelin d18:1 in which the ceramide N-acyl group is specified as hexacosanoyl. It has a role as a mouse metabolite. It is a sphingomyelin 44:1 and a sphingomyelin d18:1. It is functionally related to a hexacosanoic acid.

C26 Sphingomyelin is a sphingolipid that has been found in serum and cell or brain extracts.1,2,3 C26 sphingomyelin levels are increased in the serum of patients with hemophagocytic lymphohistiocytosis, an inflammatory condition characterized by excessive immune activation.3 C26 sphingomyelin has been used a component of monolayers to study the influence of sphingomyelin acyl chain length on sphingomyelin-sterol interactions.4 [Matreya, LLC.]
