it looks for us that this SMILES is not rendered properly in SMILES drawer (at https://doc.gdb.tools/smilesDrawer/sd/example/index_light.html)
CCCCCCCCCCCCCCCCCC(=O)SCCNC(=O)CCNC(=O)[C@H](O)C(C)(C)COP([O-])(=O)OC[C@H](N[*])C([*])=O
Closer look with: CC([*])=O
For us the double bond between C and O should be visible.
