What is Starch?

Starch is one of the most common components of our food, and is especially high in staple foods such as rice and wheat. Chemically, starch is a polymer of glucose.

The glucose units are linked together by a-1,4 and a-1,6 linkages.

Structurally, starch has two forms, amylose (which is a straight chain) and amylopectin (which is branched). a-1,4 linkages form the chains of glucose molecules and a-1,6 linkages occur at the branch points.
