Structure of a fucoidan from the brown seaweed Fucus evanescens C.Ag.
A fucoidan consisting of L-fucose, sulfate and acetate in a molar proportion of 1:1.23:0.36 was isolated from the Pacific brown seaweed Fucus evanescens. The structures of its desulfated andExpand
A highly regular fraction of a fucoidan from the brown seaweed Fucus distichus L.
A fucoidan fraction consisting of L-fucose, sulfate, and acetate in a molar proportion of 1:1.21:0.08 was isolated from the brown seaweed Fucus distichus collected from the Barents Sea. The 13C NMRExpand
13C‐nmr spectroscopy of red algal galactans
13C‐nmr spectra of red seaweed galactans, belonging to the agar and carrageenan groups or having the “intermediate” type of structure, were interpreted on the basis of 13C‐nmr spectra of modelExpand
A study of fucoidan from the brown seaweed Chorda filum.
TLDR
Other fucoidan fractions from C. filum have more complex carbohydrate composition and give rather complex methylation patterns, which correspond to a quasiregular polysaccharide structure with a branched hexasaccharide repeating unit. Expand
Further studies on the composition and structure of a fucoidan preparation from the brown alga Saccharina latissima.
TLDR
The polysaccharide composition of a fucoidan preparation isolated from the brown alga Saccharina latissima was reinvestigated and it was shown that even a single algal species may contain, at least in minor amounts, several sulfatedpolysaccharides differing in molecular structure. Expand
Structure of a fucoidan from the brown seaweed Fucus serratus L.
TLDR
The fucoidan structure was investigated by 1D and 2D 1H and 13C NMR spectroscopy of its desulfated and de-O-acetylated derivatives as well as by methylation analysis of the native and Desulfated polysaccharides. Expand
Polysaccharides of Algae XXXIII: Isolation and 13C-NMR Spectral Study of Some New Gel-forming Polysaccharides from Japan Sea Red Seaweeds
Fractional extraction of eight red seaweed species from Japan Sea was carried out and the yields and monosaccharide composition of polysaccharide fractions were determined. Six species were showa toExpand
Structure of a highly pyruvylated galactan sulfate from the Pacific green alga Codium yezoense (Bryopsidales, Chlorophyta).
A polysaccharide fraction consisting of d-galactose, sulfate, and pyruvate in a molar proportion of 4:2:1 was isolated from the green seaweed Codium yezoense by water extraction followed byExpand
Structural and genetic characterization of enterohemorrhagic Escherichia coli O145 O antigen and development of an O145 serogroup-specific PCR assay.
TLDR
The structure of the E. coli O145 O antigen and the sequence of its gene cluster are presented and putative genes for the synthesis of the O-antigen constituents, for sugar transferase, and for O-Antigen processing were annotated based on sequence similarities and the presence of conserved regions. Expand
Structure of a sulfated xylogalactan from the calcareous red alga Corallina pilulifera P. et R. (Rhodophyta, Corallinaceae).
The structure of a sulfated polysaccharide isolated from the calcareous red alga Corallina pilulifera was studied by methylation analysis before and after desulfation or Smith degradation, as well asExpand
