Impact

(A) Molecular modeling of gellan (left) and diutan (right). (B) Solid-state 13C CP/MAS spectra of gellan (left) and diutan (right). (C) 1H Liquid-state Nuclear Magnetic Resonance (NMR) spectra of gellan (left) and diutan (right). The partly suppressed water resonance (4.15–4.45 ppm) was removed from the 1H Liquid-state NMR spectra.

Enzymatic modifications of alginate. Alginate is synthesized as polymannuronan (top molecule). The mannuronic acid residues (M) may then be epimerized to guluronic acid residues (G) by mannuronan C-5 epimerases (E), O2 or O3 acetylated by mannuronan acetylases (A), or degraded by alginate lyases (L) resulting in an unsaturated 4-deoxy-L-erythro-hex-4- enepyranosyluronate residue (Δ). Acetyl groups may be removed by deacetylases (D).
