Greg Cote

I cannot tell you conclusively, but your spectrum appears to be a homopolysaccharide of a single hexose unit, with only one linkage type. My initial suspicion is that you might have dextran. Is this from a bacterial source, or perhaps sugar refinery syrups?

Arun Kumar Patchaiyappan

Dear Greg,

yes me to suppose single linkage type 1-3 linkage

whether it can be confirmed through hsqc,cosey spectrums

but this is from a plant source
