This review is concerned with the progress in the methods of structura
l analysis of sulfated galactans isolated from the red seaweeds, inclu
ding determination of monosaccharide constituents and partial depolyme
rization by reductive hydrolysis, identification of disaccharide repea
ting units by NMR spectroscopy, and sequence analysis by enzymatic deg
radation. Examples of elucidation of primary structures for several co
mplex sulfated galactans and xylogalactans are given. (C) 1998 Publish
