Hi Martin,
I know this is not your main point, but just as a point of accuracy, gum
arabic is not a long structure, but is more globular in shape, a series
of spheres rather than a long branched chain. It is very compact while
at the same time highly branched. To complicate matters further, it
actually has three components, of different molecular weight and
different compositions, but all three components have a similar
structure. I have a complete description of gum arabic on my page on the
chemistry of gum printing, but that page is waiting to be uploaded
pending the results of some chemical analyses.
