双壳类生物具有高度多样性，在各种水生环境中广泛分布，包括海水、半咸水和淡水。双壳类富含多糖，并在功能食品、药物和工业研究中具有广泛应用。尽管有许多相关报告可供参考，但信息组织不足。因此，在本研究中，我们进行了对双壳类多糖潜在生物活性的综合科学评述。总体而言，双壳类多糖具有多种生物活性，包括抗癌、抗氧化、抗凝血和免疫调节活性。这些生物分子的生物活性高度依赖于双壳类物种、提取方法、纯化方法、剂量等因素。本研究的信息可以提供双壳类多糖的生物活性概述，对于鉴定不同双壳类物种来源多糖的健康益处具有很大帮助。版权所有 © 2023 Elsevier B.V. 发布。

Bivalves have high diversity, widely distributed in various aquatic environments, including saltwater, brackish water and freshwater. Bivalves are known to rich in polysaccharides and have wide applications in functional foods, pharmaceuticals, and industrial research. Despite many relevant reports are available, the information is poorly organized. Therefore, in this study, we conducted a comprehensive scientific review on the potential bioactivity of polysaccharides derived from bivalves. In general, the polysaccharides derived from bivalves possess various bioactive properties, including anticancer, antioxidant, anticoagulant and immunomodulatory activities. The bioactivity of these biomolecules highly depends on the bivalve species, extraction methods, purification methods, dosages, etc. The information in this study can provide an overview of the bioactivities of bivalve polysaccharides. This is very useful to be used as a guide for identifying the health benefits of polysaccharides derived from different bivalve species.Copyright © 2023. Published by Elsevier B.V.
