HNK-1 carbohydrate
hnk-1 carbohydrate
HNK-1 (human natural killer-1) carbohydrate (a glycoheptaosylceramide), is characteristically expressed on a series of cell adhesion molecules in the nervous system. The HNK-1 carbohydrate has a unique structural feature, i.e. a sulfated glucuronic acid is attached to the non-reducing terminal of an N-acetyllactosamine residue (HSO3-3GlcA-β-(1→3)-Gal-β-(1→4)-GlcNAc-).
