Abstract

A full assignment of the 60°C ^13^C NMR spectrum for the reduced form of a repeat unit β‐linked tetrasaccharide derived by keratanase digestion from keratan sulphate, GlcNAc(6SO~4~)β^1–3^Gal(6SO~4~)β^1–4^GlcNAc(6SO~4~)β^1–3^‐Gal‐ol, was achieved via two‐dimensional C/H correlation and ^1^H COSY experiments, and a complete first‐order analysis of the 600 MHz proton spectrum. Partial ^13^C assignments for two fucosylated keratan sulphate pentasc‐charides derived using hydrazinolysis and nitrous acid treatment are discussed.
