Both polyglycosylceramides and polyglycosylpeptides are unbranched in i erythrocytes

Polyglycosylceramides, Poly-N-acetyllactosamine-Containing Glycosphingolipids: Methods of Analysis, Structure, and Presumable Biological Functions

“…The poly-N-acetyllactosamine chains in the PGC molecules are typically branched. Only in humans of the rare i phenotype, 58 in infants, 23 and in individuals with some rare glycosylation defects 59 are the chains mostly linear. According to permethylation-degradation analyses of PGCs (adult individuals), the branching Gal (1,3,6-linked Gal) constitutes ca.…”
