Conformational issue.

Here the G-monomer (Guluronic Acid) is represented in the unstable 4C1 conformation. The image should be re-drawn with the G-monomer in it's favored and more stable 1C4 conformation. This is actually not a trivial mistake as many of the properties of alginate are derived from this structural change. (viz. gelation by addition of divalent cations such as Ca2+.)
