摘要
A procedure is described for the quantitative determination of galactosaminitol, glucosaminitol, and their parent hexosamines by use of the automatic amino acid analyzer using cation-exchange chromatography with a borate-citrate buffer system. The method was used to study the conversion of hexosamines to hexosaminitols in several glycoproteins by alkaline borohydride under different conditions. The amount of galactosamine involved in the O-glycosidic linkage to serine and threonine in different mucins was found to be variable. In bovine, canine, and porcine submaxillary mucin 90-96% of the galactosamine lost during alkaline borohydride treatment was recovered as galactosaminitol. © 1969.
