| Abstract: | The trypsin inhibitor from bovine colostrum has been separated into several forms by CM-Sephadex and DEAE-cellulose chromatography. These forms differ in the amount and composition of the carbohydrate they contain, which has been quantitated for four components by gas-liquid chromatography and standrad colorimetric procedures. The monosaccharides fucose, mannose, galactose, galactosamine, glucosamine and sialic acids have been determined. A microheterogeneity was establish ed in the carbohydrate moiety, which amounts to about 40% of the total molecular weight (Mr 11 000 - 14 000) of bovine colostrum inhibitor. |
