Question

What is the building unit of starch?

Answer 1

1. The building unit of starch is α‑D‑glucose (glucose monomer). Starch is a polymer formed by many glucose units joined together.
2. Starch exists mainly as amylose (mostly linear chains with α‑1,4 linkages) and amylopectin (branched chains with α‑1,4 and α‑1,6 linkages).
