[A carbohydrate component of alpha1-acid glycoprotein from normal and abortive blood].
alpha 1-Acid glycoprotein (AGP) samples, viz., normal AGP (nAGP) and embryonic AGP (eAGP), were isolated from plasma of normal donor blood and abortive human blood, respectively. The materials possess similar amino acid composition and immunochemical properties. However, structural patterns of their sugar moieties differ substantially. nAGP contains only N-glycosidically bound sugar chains, whereas on eAGP some sugar chains are linked through O-glycosidic bonds. Disaccharide GlcNAc beta 1----3Gal was identified in considerable amounts in HF-solvolysate of eAGP but only as traces in nAGP.
