Cooking The varieties of rice are typically classified as long-, medium-, and short-grained. citation The grains of long-grain rice (high in amylose ) tend to remain intact after cooking; medium-grain rice (high in amylopectin ) becomes more sticky.
Starch branching enzyme introduces 1,6-alpha glycosidic bonds between these chains, creating the branched amylopectin.
It is made up of a mixture of amylose (15–20%) and amylopectin (80–85%).
Some cultivated plant varieties have pure amylopectin starch without amylose, known as waxy starches.
Amylose is a much smaller molecule than amylopectin.
