The circular dichroic spectra of the acid and sodium salt forms of several sialic acid-containing homo- and hetero-polysaccharides have been measured. The spectra are shown to be influenced by the state of ionization of the carboxyl groups contained in the sialic acid, the location within the individual sialic acid residues of the inter-saccharide linkages, and changes in the configuration of hydroxyl groups remote to the carboxyl group of the sialic acid.
已对几种含唾液酸的同聚多糖和杂聚多糖的酸形式及钠盐形式的圆二色光谱进行了测量。结果表明，光谱受唾液酸中所含羧基的电离状态、糖间键在各个唾液酸残基内的位置以及远离唾液酸羧基的羟基构型变化的影响。
