Seaweeds from the genus Gymnogongrus are known to be carrageenophytes; nevertheless, fractionation techniques used previously for the separation of gel-forming and 'soluble' carrageenans, applied to the galactans of Gymnogongrus torulosus together with enantiomeric analysis of the sugar components and (when possible) of the structural units, suggested that the system of galactans biosynthesized by the seaweed was formed by DL-galactan hybrids having major amounts of carrageenan-type or agaran-type chains, with minor quantities of agarans with unusual structural details.
裸藻属的海藻被认为是卡拉胶藻；然而，先前用于分离凝胶形成型和“可溶性”卡拉胶的分级技术，应用于圆紫菜的半乳聚糖，并对糖成分以及（可能的话）结构单元进行对映体分析，结果表明，该海藻生物合成的半乳聚糖系统是由具有大量卡拉胶型或琼脂糖型链的DL-半乳聚糖杂化物形成的，还有少量具有异常结构细节的琼脂糖。
