Hyaluronic acid double helix.

Arnott S, et al. J Mol Biol. 1983.

Abstract

The hyaluronic acid double helix, contrary to an earlier visualization, probably incorporates extensively hydrogen-bonded chains and is pinned together by carboxyl-carboxylate hydrogen bonds and water bridges. Transient interactions between stiffened chain segments provided by the formation of double-helical loops could give rise to the characteristic viscoelastic properties of hyaluronic acid solutions.
