How would you make a starch molecule? What is the name of the bond formed between glucose molecules?
I think I got it. They are formed by long chains of glucose molecules joined together by a glycosidic link.
Can anyone confirm if this is correct?
I believe you are right. Check this out.

Yes, you are correct! Starch molecules are composed of long chains of glucose molecules joined together by glycosidic linkages. Specifically, starch is made up of two types of glucose polymers: amylose and amylopectin.
Amylose is a linear polymer of glucose molecules joined together by α(1->4) glycosidic bonds. This means that the glucose molecules are connected through a specific type of bond called an α(1->4) glycosidic bond.
Amylopectin, on the other hand, is a branched polymer of glucose molecules. It has both α(1->4) glycosidic bonds and α(1->6) glycosidic bonds. The α(1->4) glycosidic bonds connect the glucose molecules within the chain, while the α(1->6) glycosidic bonds form branches in the structure.
By joining many glucose molecules together through these glycosidic bonds, starch molecules form a complex network of chains and branches, creating a storage form of glucose in plants.
