Hydrogen‐bonded conformation of hyaluronate oligosaccharide fragments in aqueous solution

Abstract
The hydrogen bonding in hyaluronate oligosaccharide fragments was studied in aqueous solution using hydrogen‐tritium exchange techniques. The data reveal an acetamido hydrogen exchange rate that is 5–6‐fold slower than that seen in model compounds. The magnitude of the slowing is interpreted as reflecting the participation of an acetamido hydrogen in a relatively labile intramolecular hydrogen bond.
