From: β-elimination of hyaluronate by red king crab hyaluronidase

\(^1\)H-NMR spectra of the reaction mixtures containing HA after treatment by:
S. hyalurolyticus lyase,
HPC homogenate,
leech head homogenate. (a)—The signal of protons of N-acetyl-D-glucosamine acetyl group of HA chains, (b)—The \(^1\)H signal of protons at double bond in \(\Delta ^{4,5}\)-unsaturated glucuronic acid residue.
