What monosaccharides make up starch?
Only one monosaccharide makes up starch, and that is glucose.
Starch exists in two different forms: amylose and amylopectin.
Each form is a polymer of glucose molecules.
The structure of glucose,
Amylose consists of long, chain-like molecules of glucose units joined together.
The structure of amylopectin is similar to that of amylose, but there are numerous branches along the chain.
We could write the equation for the formation of starch in either form as
