Galactoarabinan(Arabinogalactan) is a biopolymer consisting of arabinose and galactose monosaccharides. Two classes of arabinogalactans are found in nature: plant arabinogalactan and microbial arabinogalactan. It is often found attached to proteins, and the resulting arabinogalactan protein (AGP) functions as both an intercellular signalling molecule and a glue to seal plant wounds. The microbial arabinogalactan is a major structural component of the mycobacterial cell wall.

The mycobacterial arabinogalactan is recognized by a putative immune lectin intelectin present in chordates.

The non-reducing end of arabinogalactan is covalently attached to the mycolic acids of the outer membrane.


Currently, Galactoarabinan(Arabinogalactan) is used in many ways. As an additive in food, animal feed, cosmetic, pharmacy, construction, pulp production, oil production, plant growth, etc. Arabinogalactan can be used as an additive in the way it is or in combination. Arabinogalactan main use is as a replacement for gum arabic, guar gum, and starch in food, cosmetic and pharmaceutical products. Using Arabinogalactan leads to more efficient land distribution, leaving more land for agricultural purposes. It plays an essential role in environmental preservation, as manufacturers use non-polluting biorefinery processes.
