Abstract

We measured the binding-state-dependent power absorptions, refractive indices, and dielectric constants of triple-stranded helices (TSHs) and single-stranded helices (SSHs) Β -glucans in laminarin using terahertz time-domain spectroscopy (TDS). The SSH Β -glucan was obtained from a TSH Β -glucan laminarin by a chemical treatment with NaOH solution. The power absorption of TSH Β -glucan increased more rapidly than that of the SSH Β -glucan with the frequency increment. The refractive index and dielectric constants of TSH Β -glucan were also larger than those of the SSH Β -glucan. This result implies that terahertz-TDS is a very effective method in classifying the conformational state of Β -glucans.
