Local conformation

  "id": "MLC-T-CHM-006731",
  "term": "Local conformation",
  "field": "Chemistry",
  "definition": "The spatial arrangement of atoms in a small, contiguous part of a macromolecule, such as a constitutional unit or a short sequence of units. This arrangement is described by the set of torsion angles (dihedral angles) along the polymer backbone within that specific segment. The local conformation determines short-range interactions, while the collection of all local conformations defines the overall shape of the polymer chain.",
