MS percent total ion abundances of all oligosaccharide chains present in all juvenile bovine and adult human cartilage samples. Oligosaccharide compositions are given as (HexA, GalNAc, SO3) (X,Y,Z), with Δ indicating 4,5-unsaturation of the non-reducing terminal HexA residue. Tetrasaccharide linker compositions are given as (Xyl, Gal, HexA, SO3) (V,W,X,Z). Hexasaccharide linker compositions are given as (Xyl, Gal, HexA, GalNAc, SO3) (V,W,X,Y,Z).
