Molecular weight distribution and structural characterization of Gelidiopsis variabilis variabilis polysaccharide fractions.

Description

This dataset contains the raw analytical data supporting the structural characterization of six polysaccharide fractions extracted from Gelidiopsis variabilis (GV-1A, GV-1B, GV-2A, GV-2B, GV-3A, and GV-3B). The dataset includes high-performance size-exclusion chromatography (HPSEC) chromatograms for molecular weight distribution analysis, Fourier-transform infrared (FTIR) spectra (400–4000 cm⁻¹) for functional group identification, and full-range proton nuclear magnetic resonance (¹H NMR) spectra for detailed structural characterization. These raw data provide supporting evidence for the molecular features, chemical composition, and structural differences among the GV polysaccharide fractions reported in the associated research article.
