Fig. 4: Glycan content of snail mucus.
From: Comparative mucomic analysis of three functionally distinct Cornu aspersum Secretions

Structures and relative abundance of a O-glycans and b N-glycans found in each isolated mucus secretion by glycomic mass spectrometry. Glycans shown comprised >5% of glycomic abundance. Trace O- and N-glycans (<5% abundance) are listed in Supplementary Tables 9 and 10, respectively. Inset in ‘b’ lists monosaccharide structures as defined by the symbolic nomenclature for glycans (SNFG). Red: adhesive; blue: lubricating; green: protective.
