从儿童前牙列唇侧采集的牙菌斑中含有奈瑟氏菌，该菌可从蔗糖中合成细胞外嗜碘多糖（EIP）。完全乙酰化的EIP衍生物的气相色谱图表明，葡萄糖（97%）和半乳糖（3%）是唯一的单糖成分存在。EIP的部分甲基化的糖醇乙酸酯（PMAA）衍生物的表征表明，它主要是线性1，4葡聚糖（75.5%），与一些1，6葡聚糖（8.4%）。与直链淀粉和糖原相比，EIP的相对线性（96.6%）通过分光光度法吸收研究得到证实。
Dental plaque collected from the labial aspect of the anterior dentition of children harbored Neisseria that synthesized an extracellular iodophilic polysaccharide (EIP) from sucrose. Gas chromatograms of fully-acetylated EIP derivatives indicated that glucose (97%) and galactose (3%) were the only monosaccharide constituents present. The characterization of the partially-methylated alditol acetate (PMAA) derivatives of EIP indicated that it was primarily a linear 1,4 glucan (75.5%), with some 1,6 glucan (8.4%). The relative linearity of EIP (96.6%) as compared to that of amylose and glycogen was confirmed by spectrophotometric absorption studies.
