WebN-Palmitoylsphingomyelin is a natural product found in Trypanosoma brucei with data available. N-hexadecanoylsphingosine -1-phosphocholine is a sphingomyelin 34:1 in which the N-acyl group and sphingoid base are specified as hexadecanoyl and sphingosine respectively. It has a role as a mouse metabolite. WebSphingolipid. Sphingolipids are a class of lipids containing a backbone of sphingoid bases, a set of aliphatic amino alcohols that includes sphingosine. They were discovered in brain extracts in the 1870s and were named after the mythological sphinx because of their enigmatic nature. [1]
