The amylose–dimethyl sulfoxide complex has been investigated with the aid of x‐ray diagrams of oriented fibers. The amylose occurs in a six‐residue helix with alternate “up” and “down” chains packed in a square array, that is, pseudo‐tetragonal. A unit cell is proposed with a = b = 19.21 A. and c = 8.12 A.
