Each glucose unit in a molecule of cellulose has three hydroxyl groups that can be used to derivatize the cellulose by reactions common to all alcohols. It is uncommon, and for some derivatives impossible, to achieve a degree of substitution (DS) of three. Most important derivatives of cellulose have a DS that is somewhat below that value. For a given deriva­tive, the DS must be specified since the properties of the derivative depend almost as much on DS as they do on the substituting agent.
