Task: Please create a description for a molecule based on its representation.
SMILES: CCCCCCCCCCCCCCCCCCCCCCCCCC(=S)N[C@@H](CO[C@H]1O[C@H](CO)[C@H](O)[C@H](O)[C@H]1O)[C@H](O)[C@H](O)CCCCCCCCCCCCCC
Constraint: Answer the question with complete sentences.
Result: The molecule is a glycosphingolipid identical with alpha-galactosylceramide (alpha-GalCer) with the exception of the replacement of the C-2 carbonyl oxygen on the acyl chain with a sulfur atom. It has a role as an antigen. It is a thiocarboxamide and a glycosphingolipid. It derives from a 1-O-(alpha-D-galactosyl)-N-hexacosanoylphytosphingosine.
