Structural elucidation of a novel heteropolysaccharide from Arca inflata Reeve and its immunomodulatory and antioxidant activities
A novel acidic homogeneous polysaccharide (AIPW50-1) with a molecular weight of 214.5 kDa was isolated by hot water extraction and several column chromatographic purification methods from Arca inflata Reeve.The repeating structural units of AIPW50-1 were elucidated by the combined chemical and instrumental analyses.AIPW50-1 is composed of glucose,
