软体动物是一种富含糖醛酸多糖（UACP）的生物资源。本研究系统地分析了5种食用贝类（Neverita didyma、Natica janthostomoides、Saxidomus purpurata、Cyclina sinensis和Chlamys farreri）不同组织的UACP组成。共观察到10种UACP，包括硫酸软骨素、肝素、一种已鉴定的甘露糖醛酸、3种未知的具有己糖醛酸-己糖胺重复单元的糖胺聚糖（GAG，U1、U3和U6）和4种未知的具有己糖醛酸-己糖重复单元的非GAG（U2、U4、U 5和U 7）。U4-7具有组织特异性和种特异性，而其他UACP普遍存在于这些贝类组织中。来自相同贝类的组织中的UACP组成相似。purpurata和C. farreri，新几内亚牛肝菌N. didymaandN.拟刺口鱼研究还表明，不同贝类之间UACPs组成的相似性与亲缘关系有关。
Mollusks are a rich source of uronic acid-containing polysaccharides (UACPs) possessing biological and pharmacological activities. In the present study, UACP compositions of different tissues from 5 species of edible shellfishes, namelyNeverita didyma,Natica janthostomoides,Saxidomus purpurata,Cyclina sinensis, andChlamys farreriwere systemically analyzed. Totally 10 UACPs were observed, including chondroitin sulfate, heparin, an identified mannoglucuronan, 3 unknown glycosaminoglycans (GAGs, U1, U3 and U6) with hexuronic acid-hexosamine repeating units, and 4 unknown non-GAGs (U2, U4, U5 and U7) with hexuronic acid-hexose repeating units. U4-7 showed tissue- and species-specificity while the other UACPs prevalently existed in these shellfish tissues. UACP compositions in tissues from the same shellfish species were similar forS. purpurataandC.sinensisbut different forC. farreri,N. didymaandN. janthostomoides. And this investigation also indicates that the similarity of UACPs composition between different shellfishes is related to the genetic relationship.
