polyalcohol oxidase and dehydrogenase activities were assayed in the digestive gland of 26 species of gastropods, representing the clades Patellogastropoda, Neritimorpha, Vetigastropoda, Caenogastropoda and Heterobranchia. Marine, freshwater and terrestrial species, including herbivores and carnivores were analyzed. Ultrastructural observations were undertake in species possessing mannitol oxidase
甘露醇氧化酶和多元醇脱氢酶是将多元醇转化为糖的酶。以前曾在陆地蜗牛和中研究过甘露醇氧化酶,但在一些水生腹足动物中也存在过。但是,该酶在腹足纲动物中的总体分布是未知的。在腹足动物和其他软体动物中对多元醇脱氢酶的研究也很少。在这项研究中,对26种腹足纲动物的消化腺中的多元醇氧化酶和脱氢酶活性进行了测定,代表了Patellogastropoda,Neritimorpha,Vetigastropoda,Caenogastropoda和杂种支原体进化枝。分析了海洋,淡水和陆生物种,包括草食动物和食肉动物。对具有甘露醇氧化酶的物种进行了超微结构观察,为了研究这种酶与已知与其相关的管状结构之间的相关性。在Caenogastropoda和Heterobranchia进化枝的食草动物的消化腺中检测到甘露醇氧化酶活性,但在任何食肉动物或Patellogastropoda,Neritimorpha和Vetiga
