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]
Galactan is found in the side chains of rhamnogalacturonan I (RG-I) and is needed for gel formation in the cell walls of organisms. [7] It was observed there was less of the gelling characteristic (as well as the polymeric chains being more likely to degrade) when fewer galactans were present in the polymeric side chains. [7] [8]
