N-Heptadecanoyl-D-erythro-sphingosine

Sphingosine derivative from red algae of the Ceramiales. Sphingolipids, such as ceramides and cerebrosides, are important molecules in the formation and maintenance of the epidermal barrier to water vapor diffusion.

ChEBI: N-heptadecanoylsphingosine is a N-acylsphingosine in which the ceramide N-acyl group is specified as heptadecanoyl. It is functionally related to a heptadecanoic acid.
