  "notes": "front faces -Y; teaching ribbon model of a small alpha/beta protein: a twisted antiparallel beta sheet of four yellow arrow ribbons (arrow heads point towards the C terminus) joined by tight hairpin turns, two red right handed alpha helices as ribbons (three turns each, true pitch and radius at 6 mm per angstrom), all loops and both chain ends as round mint tubes. A steel rod with a small ball clamp holds the loop between the fourth strand and the first helix on a lilac domed stand. One solid mesh, no movable parts.",
