Supplementary Fig. 1

Addition of cholesterol metabolites (2/3) and (4) is toxic to SHSY5Y cells, whereas cholesterol is not toxic.

Supplementary Fig. 2

Electron microscopy (EM) images for control alphaS aggregation reactions.

Supplementary Fig. 3

alphaS catalyzes the conversion of oxidative metabolite (2) into (3) as measured by thin layer chromatography (TLC).

Supplementary Fig. 4

The hastening of alphaS fibrilization by (4) is not affected by addition of the competitive Schiff-base inhibitor aminoguanidine.
