What do potatoes and wood lobster shells have in common?

* Potatoes are a well-known source of starch, which is a complex carbohydrate that provides energy.

* Wood lobster shells may not be as commonly known for their starch content, but they do contain a type of starch called chitin. Chitin is a structural polysaccharide found in the exoskeletons of arthropods like lobsters, crabs, and insects.

While both potatoes and wood lobster shells contain starch, they are different types of starch with different chemical structures and uses.
