This entity has been manually annotated by the ChEBI Team.
The structure shown is an example of a repeating unit. Each monosaccharide may be unsulfated, sulfated once, or sulfated twice. Most commonly the hydroxy groups of the 4- and 6-positions of the N-acetyl-galactosamine are sulfated, with some chains also having sulfation at the 2-position of the iduronic acid.
