The molecule is a sphingomyelin 33:1 obtained by formal condensation of the carboxy group of hexadecanoic acid with the amino group of 15-methylhexadecasphingosine-1-phosphocholine. It is a metabolite of the nematode Caenorhabditis elegans. It has a role as a Caenorhabditis elegans metabolite. It derives from a 15-methylhexadecasphing-4-enine and a hexadecanoic acid.
