It was undertaken to ascertain whether sialic acid found in cartilage was a component of proteinpolysaccharide (PP) or of cartilage residue which mainly consisted of collagen.
The remains of cartilage left after the extraction of PP were fractionated into three frac tions. These and PP were analyzed for their sugar components and collagen. The sialic acid content was high with increase in the uronic acid content, while low with increase in the collagen content. Since the uronic acid and collagen were indices of PP and cartilage residue respectively, it was concluded that the sialic acid was a component of PP.
