Abstract
Three oligosaccharide alditols, a di (44–63%), tetra (32–46%), and a pentasacchariditol (5–10%) have been isolated from desialylated caseinomacropeptide obtained from ϰ-casein of ewe colostrum. The disacchariditol is 2-acetam-do-2-deoxy-3-O-(β-D-galactopyranosyl)galactitol; in the tetrasaccharide this unit is substituted in position 6 of the galactosaminitol moiety by 2-acetamido-2-deoxy-4-O-(β-D-galactopyranosyl)-β-D-glucopyranose, while the pentasacchariditol is derived from the tetrasaccharide by addition of a D-galactopyranosyl unit to position 3 of the galactopyranose unit substituting the glucosamine unit.This publication has 35 references indexed in Scilit:
