A protocol to identify uronic acid-containing polysaccharides (UACPs) was presented.
Oligosaccharides from acid hydrolysis were characterized for UACP identification.
UACPs in 5 mollusks were identified using a combination of two mass spectrometers.
A non-glycosaminoglycan, →4)-β-GlcA(1 → 2)-α-Man(1→ was found in 3 mollusks.
Chondrotin sulfate was also observed in 4 of the 5 mollusks.
