Viscoelasticity of hyaluronic acid with different molecular weights
Abstract
Storage and loss moduli of hyaluronic acid solutions with different molecular weights were observed as a function of frequency in the presence of sugars and salts. The hyaluronic acid solutions of higher molecular weight (Mw > 17 x 10(6)) fractions showed entanglement, whereas lower molecular weight fractions did not. For inducing the entanglement of molecular chains of hyaluronic acid, increasing the molecular weight of hyaluronic acid was more effective than increasing the concentration of the lower molecular weight fractions (Mw = 7. 8 x 10(5). Glucose, fructose, galactose, and sucrose increased both storage and loss moduli, while NaCl, KCl and CaCl2 decreased both moduli. It is suggested that sugars create hydrogen bonds and strengthen the transient network. Cations shield the electrostatic repulsion of hyaluronic acid molecules, and the polymer chains are shrunk into compact coils from expanded stiffened coils.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
