| In the PCW, uronic acid residues are found as constituents of xylans, pectins, glucuronomannans and arabinogalactan-proteins. |
| Walls consist of a porous network of cellulose fibrils, hemicellulose, pectins, and glycoproteins. |
| In citrus hesperidia, the creasing of albedo appears to be strictly related to a decrease of cell wall pectins beyond a critical level. |
| Major constituents of the cell wall are cellulose, hemicelluloses and pectins. |
| In some cases, sections were submitted to enzymatic or chemical treatments before immunolabelling, for the in situ de-esterification of pectins. |
| Proteins, pectins, polysaccharides and glycolipids, organized in a three-dimensional polygonal frame are part of the structural elements. |
