Serum amylase catalyzes the hydrolysis of α‑1,4 glycosidic bonds in starch molecules, yielding glucose, maltose, and dextrins. Iodine can bind to unhydrolyzed starch to form a complex, which exhibits a characteristic absorption peak at 570 nm. Therefore, the activity of serum amylase can be characterized by measuring the change in absorbance.
