Building block (monomer) of starch:

  1. β-D-Glucose
  2. α-D-Glucose
  3. Galactose
  4. Fructose
Show answer and solution

Correct answer: B. α-D-Glucose

**Starch:** polymer of α-D-glucose units linked by α-1,4 (and some α-1,6) glycosidic bonds. **Two components:** amylose (linear) and amylopectin (branched). **Cellulose differs:** β-D-glucose linked by β-1,4.
