- Cellulose is a complex carbohydrate composed
- of long chains of glucose units. It is the
- principal constituent of the cell wall of
- most plants, and a vital ingredient in the
- diet of many herbivores. Molecules of
- cellulose are organized into long,
- unbranched microfibrils that give support to
- the cell wall. No mammal produces the enzyme
- necessary for digesting cellulose. Mammals
- such as rabbits and cows are only able to
- digest grass because the bacteria present in
- their gut manufacture the appropriate enzyme.
- Cellulose is the most abundant substance
- found in the plant kingdom. It has numerous
- uses in industry, including rope-making and
- plastics.
