Natural Functions
Hemicellulose in Plant Cells
- Along with cellulose in plant cell walls, hemicellulose helps to strengthen the cell wall
- Hemicellulose are also a polysaccharide compound in plant cell walls similar to cellulose[1]
- The hemicellulose compound interacts with the cellulose by providing cross-linking of cellulose microfibrils[2]
- Hemicellulose will search for voids in the cell wall during its formation and provide support around cellulose fibrils[1]
- This process is done by hemicellulose in order to equip the cell wall with the maximum possible strength it can provide
- Hemicellulose dominates the the middle lamella of the plant cell, unlike cellulose which is primarily found in the secondary layers[2]
- This allows for hemicellulose to provide middle-ground support for the cellulose on the outer layers of the plant cell
- Hemicellulose will search for voids in the cell wall during its formation and provide support around cellulose fibrils[1]
- In few cell walls, hemicellulose will also interact with lignin to provide structural tissue support of more vascular plants[3]
