The presence of N-acetylmuramic acid in glycoconjugates in various mollusc tissues was investigated by histochemical and immunocytochemical techniques. The tissues studied included foot, mantle, digestive gland, ganglia and haemocytes of Helix aspersa, Planorbarius corneus, Murex brandaris and Trunculariposis trunculus. Sialic acid residues were found to be absent. The possibility that N-acetylmuramic acid replaces sialic acid in acid glycoconjugates of gastropods with similar properties is discussed.
通过组织化学和免疫细胞化学技术研究了各种软体动物组织中糖缀合物中N - 乙酰胞壁酸的存在情况。所研究的组织包括盖罩大蜗牛、角扁卷螺、红螺和截尾海兔的足部、外套膜、消化腺、神经节和血细胞。发现不存在唾液酸残基。讨论了N - 乙酰胞壁酸在具有相似性质的腹足纲动物酸性糖缀合物中取代唾液酸的可能性。
