The anhydroglucose unit (AGU) refers to a single sugar molecule in a polymer. Each AGU is reduced to its functional groups, 3 hydroxyl groups per AGU.
Carbohydrate AGU:
| Polymer | AGU | mmol -OH/g |
|---|---|---|
| Amylose | 200-2000 |
Cellulose AGU:
| Polymer | AGU | mmol -OH/g |
|---|---|---|
| cotton fibers | 4,000-7,000 | |
| cotton linters | 500-3,250 | |
| baggase | 350-450 | |
| wood fibers | 4,000-4,500 |
