A-Glycolyl groups

There is some evidence for the occurrence of a glycolyl group at 0-4 of Neu5Ac in serum and submandibular-gland glycoproteins from the horse, based on biosynthetic studies with radioactive precursors,33 and chemical and t.l.c. analysis of the sialic acid ester groups.74... [Pg.146]

The A-glycolyl group can be an acceptor site of 0-acetylation and O-methylation, yielding Neu5GcAc and NeuSGcMe (Table 1) in rat thrombocytes and starfish, respectively [43,44]... [Pg.321]

Sialic acids are important constituents of glycoconjugates, often located peripherally on glycoproteins. This family of natural CAAs consists of N- and O-acyl derivatives of neuraminic acid 2 the main substituents on nitrogen are the iV-acetyl and A-glycolyl groups [14],... [Pg.566]

Fig. 4—A comparison of the H-D antigenic component and the receptor for influenza virus hemagglutinin, which are a-NeuGc-(2 — 3)-/ -Gal and a-NeuAc-(2 — 3)-/ -Gal, respectively, on the backbones / -D-Gal-( 1 — 4)-jS-d-G1cNAc-( 1 -> 3)-jS-D-Gal-(l - 4)-d-G1cNAc (sialyl i), yS-D-Gal-(l — 4)-yJ-D-GlcNAc-(l - 6)-D-Gal (sialyl I). The CH3 of the acetamido group of Ar-acetylneuraminic acid, which is a CH2OH group in iV-glycolyl-neuraminic acid, is shown.
