Structure of arabinogalactan-protein from Acacia gum: From porous ellipsoids to supramolecular architectures

► AGPs from Acacia gum are made of macromolecules with compact and elongated conformations. ► AGPs are either single either aggregated flat particles. ► Aggregated particles are made of AG units or fused AGPs dimers, trimers, multimers. ► AGPs have an inner more or less porous network of interspersed chains.
