  "summary": "Two low-molecular-weight alginic acid fractions, G-block-rich SKP-G1 and M-block-rich SKP-G2, were sequentially isolated from a hot-water extract of sugar kelp (Saccharina latissima) alcohol-insoluble residue by acetic acid-induced and subsequent freeze-thaw-induced gelation. High-field (700 MHz) 2D 1H-1H COSY and TOCSY spectroscopy enabled comprehensive cross-peak assignments for selected…",
