Galactan (galactosan) is a polysaccharide consisting of polymerized galactose.[1] In general, galactans in natural sources contain a core of galactose units connected by α(1→3) or α(1→6), with structures containing other monosaccharides as side-chains.[2]

Galactan derived from Anogeissus latifolia is primarily α(1→6), but galactan from acacia trees is primarily α(1→3).[3]
Halymenia durvillei is a red seaweed (algae) that produces a sulfated galactan.[4] Several other algae species also contain galactans.[5] Including Carpopeltis F.Schmitz, 1895.[6]
