The nitrogen-containing polysaccharide obtained from human placenta was submitted to periodate oxidation and methylation. From the result of molar number of periodic acid consumed, molar number of formic acid formed, and from the estimation and determination of the methylated monosaccharides obtained, a structure represented in Fig. 1 was proposed for the polysaccharide.
