The polysaccharide antigen produced by Eubacterium saburreum, strain L 49, is composed of D-glycero-D-galacto-heptose and a new sugar, tentatively identified as 6-deoxy-D-altro-heptose. It contains chains of alternating (1 leads to 3)- and (1 leads to 6)- linked beta-D-glycero-D-galacto-heptopyranosyl residues, the latter being substituted with 6-deoxy-alpha-heptofuranosyl groups at O-3. The polysaccharide further contains 0-acetyl groups, linked to O-7 of part of the heptosyl residues and to O-2 of part of the 6-deoxyheptosyl groups.
由迟缓真杆菌L 49菌株产生的多糖抗原由D-甘油-D-半乳庚糖和一种新糖（暂鉴定为6-脱氧-D-阿卓庚糖）组成。它含有交替连接的（1→3）-和（1→6）-连接的β-D-甘油-D-半乳庚吡喃糖基残基链，后者在O-3位被6-脱氧-α-庚呋喃糖基取代。该多糖还含有O-乙酰基，连接到部分庚糖基残基的O-7位和部分6-脱氧庚糖基的O-2位。
