Abstract

Collagen-like structures were formed in solutions of α-elastin after heating to 57°C and after treatment with absolute ethanol. A complex between acetyl-α-elastin and cetyltrimethylammonium bromide showed a similar structure. Thick fibrils (diameter approximately 100 nm), resembling those described by Volpin, et al.¹² revealed transversal banding with periodicity of 39 to 62 nm. A possible mechanism for the formation of these fibers is suggested based on hydrophobic interactions.
