Branching takes place with α(1 6) bonds occurring every 24 to 30 glucose units.

There may be from 60 to 300 glucose units per chain.

There may be 300 to 6000 glucose units per amylo pectin molecule.

Some carbohydrates, such as cellulose, are not digested at all, despite being made of multiple glucose units.

Amylopectin is highly branched, being formed of 2,000 to 200,000 glucose units.

Cellulose is a polysaccharide consisting of 3,000 or more glucose units.

Each is notated with V and then a subscript indicating the number of glucose units per turn.

The most common is the V6 form, which has six glucose units a turn.

Optimum activity is on those 1,6-alpha-D-glucans containing 6, 7 and 8 glucose units.

Another of the glucose units appears as a 6-deoxy variant.
