Task: Please create a description for a molecule.
Molecule SMILES: CCCCCCCCCCCCC/C=C/[C@H](O)[C@H]([NH3+])CO
Constraint: Answer the question with complete sentences.
Result: The molecule is a cationic sphingoid resulting from the protonation of the amino group of L-erythro-sphingosine; major species at pH 7.3. It is a conjugate acid of a L-erythro-sphingosine. It is an enantiomer of a sphingosine(1+).
