This will constitute the bulk of the discussion and will be followed by the presentation of the results of the analyses of two brains of patients with Tay-Sachs' disease.Strandin1 was reported originally as a complex lipide which had been isolated from gray matter by three different methods. Its name was chosen because, when recovered from water solutions by drying, strandin was obtained as a residue of long, glistening, birefringent strands. It was readily soluble in water as an undialyzable solute which was homogeneous in the electrophoretic field over a wide pH range. By ultracentrifugation it showed a major component which accounted for 80% of
