There is a common structure (core region) in the lipopolysaccharides of Rhodospirillum tenue. It is composed of a branched trisaccharide of L-glycero-D-mannoheptose (and of 2-keto-3-deoxyoctonate), as revealed by methylation analyses of degraded polysaccharides of four different R. tenue strains. The structure is similar or might even be identical to the inner core of enterobacterial O antigens. In addition, each of the four R. tenue lipopolysaccharides contains a strain-specific region that consists of heptose(s) (L-glycero-D-mannoheptose or D-glycero-D-mannoheptose or both) or hexoses. There is a partial substitution of the core region and the strain-specific region by phosphorus, showing microheterogeneity.
纤细红螺菌的脂多糖中存在一种共同结构（核心区域）。通过对四种不同纤细红螺菌菌株的降解多糖进行甲基化分析发现，它由L-甘油-D-甘露庚糖（以及2-酮-3-脱氧辛酸）的分支三糖组成。该结构与肠杆菌O抗原的内核相似，甚至可能相同。此外，四种纤细红螺菌脂多糖中的每一种都含有一个菌株特异性区域，该区域由庚糖（L-甘油-D-甘露庚糖或D-甘油-D-甘露庚糖或两者）或己糖组成。核心区域和菌株特异性区域存在部分磷取代，表现出微异质性。
