Abstract

Structure of fucoidan from sea cucumber Acaudina molpadioides (Am-FUC) was investigated in this study. Low molecular weight polysaccharide of Am-FUC (Am-LMW) was prepared by enzymatic degradation and assayed by nuclear magnetic resonance. According to the structure of Am-LMW, and referring to previously reported information of Am-FUC oligosaccharides, the structure of Am-FUC was elucidated as [→3-α-L-Fucp-1 →3-α-L-Fucp2,4(OSO -3)-1→3-α-L-Fucp-1→3-α-L- Fucp2(OSO-3 )-1→]n. Compared to other investigated fucoidans, which also consist of tetrafucose repeating units with 1?3-linkages, Am-FUC contains a novel repeating unit distinctive in sulphation pattern.
