From bovine nasal cartilage two products were isolated, each consisting mainly of chondroitin sulfate and protein (1). These were called proteinpolysaccharides (PP), and the two kinds were distinguished as PP-H and PP-L. Human costal cartilage also yielded two products which, in the extraction and fractionation procedures, behaved rather like the two products from bovine nasal cartilage and were also called PP-H and PP-L (2), although they differed from the corresponding products from bovine cartilage in yield and composition. Isolation and fractionation of the products from human cartilage was far more difficult and gave results more variable than with bovine cartilage. The PP of bovine and human cartilages contain components other than chondroitin sulfate and protein. Partridge and his co-workers (3, 4) found glucosamine and galactose among degradation products of PP from cartilage. Gregory and Roden found keratan sulfate after digestion of bovine nasal PP-L with hyaluronidase and papain (5). Alkaline degradation of bovine nasal PP-L also gave keratan sulfate in an amount 5% of the weight of the PP-L (6). Meyer and his co-workers (7, 8) reported obtaining keratan sulfate from whole human costal cartilage and found this component to increase with age. Anderson (9, 10)
