FT-IR spectra of alginic acid block fractions in three species of brown seaweeds
D Leal, B Matsuhiro, M Rossi, F Caruso - Carbohydrate research, 2008 - Elsevier
Sodium alginates obtained by alkaline extraction of Lessonia flavicans, Desmarestia ligulata
and Desmarestia distans (Phaeophyta) from southern Chile were partially hydrolyzed with
HCl. Each alginate gave three fractions that were characterized using FT-IR spectroscopy.
The fractions soluble in 0.3 M HCl presented in the fingerprint region four vibrations at
around 960, 911, 890 and 815cm− 1 that were assigned to heteropolymeric blocks. The
fractions soluble at pH 2.85 showed bands at around 948, 888 and 820cm− 1 attributed to …
