Aqueous extraction of the red alga C. rubrum gave a galactan sulphate and, possibly, a separate glucan and xylan. The galactan sulphate has an alternating structure of the agar-type with D-galactose or 6-O-methyl-D-galactose as one alternating unit, and L-galactose, 3,6-anhydro-L-galactose, and their respective 2-methyl ethers as the other unit. Sulphate hemi-ester groups are present on position 6 of both D- and L-galactose residues, with smaller amounts on positions 2 and 4 of, probably, D-galactose residues. The polysaccharide differs from others previously examined in that most of the L-galactose residues are non-sulphated.
对红藻红海束毛藻进行水提取得到了一种硫酸半乳聚糖，可能还得到了一种单独的葡聚糖和木聚糖。硫酸半乳聚糖具有琼脂型的交替结构，其中D-半乳糖或6-O-甲基-D-半乳糖作为一个交替单元，L-半乳糖、3,6-脱水-L-半乳糖及其各自的2-甲基醚作为另一个单元。硫酸半酯基团存在于D-和L-半乳糖残基的6位，可能在D-半乳糖残基的2位和4位有少量存在。该多糖与之前检测的其他多糖不同，在于大多数L-半乳糖残基是非硫酸化的。
