  "id": "MLC-T-CHM-010585",
  "term": "s-cis, s-trans",
  "field": "Chemistry",
  "definition": "Conformational isomers that arise from rotation around a single bond connecting two sp2-hybridized atoms, where the single bond has partial double bond character. The 's' denotes single bond, distinguishing these from cis-trans isomerism around a double bond. In an s-cis conformation, two reference groups on adjacent atoms are on the same side of the single bond, while in s-trans they are on opposite sides.",
