Ultracentrifugal analysis of approx. 0.1% w/v solutions of the sparingly soluble materials indicate that they have much larger sedimentation coefficients (S20,w) and molecular weights than have the water-soluble glycoproteins. The sparingly soluble substances have more total amino acids and proportionally more aspartic and glutamic acids and cystine and less serine and threonine than have the soluble glycoproteins. The sparingly soluble substances mostly dissolve in buffered (pH 6.8–7.0, 0.05 M) solutions of thioglycolate, sulphite or cysteine, reagents that bring about the scission of -S-S-bonds. The behaviour and properties of the sparingly soluble glycoproteins suggest that they arise through the building up of relatively small glycoproteins to larger macromolecules through the formation of -S-S- intermolecular associations. A number of ways whereby the formation of these sparingly soluble glycoproteins could occur are discussed.</div>","PeriodicalId":100163,"journal":{"name":"Biochimica et Biophysica Acta (BBA) - Mucoproteins and Mucopolysaccharides","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1965-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0926-6534(65)90009-6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"16407509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After single intraperitoneal injections, about 20% of administered radioactivity was excreted in urine within 6 h. Only 1% was found in expired CO2 at this time; 12% was found at 72 h. High levels of bound (non-dialyzable) radioactivity appeared first in liver and then in serum. Non-dialyzable radioactivity in serum was found associated with all electrophoretically separated fractions with the greatest concentration in the α-globulins. Hexosamines were separated by paper chromatography from serum protein hydrolysates; glucosamine had a 14C content over ten times that of galactosamine in a sample taken 6 h after injection. A progressive increase in non-dialyzable radioactivity with time was found in both connective tissue and the fluid from within stainless-steel wire mesh cylinders implanted subcutaneously 2 weeks prior to injection of [1-14C]galactosamine. Mucopolysaccharides, extracted from connective tissue, exhibited electrophoretic mobility and staining characteristic of chondroitin sulfate and hyaluronic acid. Although hyaluronic acid and chondroitin sulfate moieties were labeled to the same extent, their hydrolysates contained glucosamine with 4 times more radioactivity then galactosamine, possibly indicating the presence of a substance containing glucosamine in the chondroitin sulfate area. These results indicate that much of the galactosamine is converted to glucosamine. Radioactive galactosamine appears to be of value for metabolic studies of glycoproteins and mucopolysaccharides.</div>","PeriodicalId":100163,"journal":{"name":"Biochimica et Biophysica Acta (BBA) - Mucoproteins and Mucopolysaccharides","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1965-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0926-6534(65)90003-5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91632741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
