Investigating the effect of pH on amylase activity

WebBy acting at random locations along the starch chain, α-amylase breaks down long-chain carbohydrates, ultimately yielding maltotriose (three glucoses) and maltose (two glucoses) from amylose or maltose, glucose, and dextrins (mixtures of polymers of d-glucose units linked by α-(1 → 4) or α-(1 → 6) bonds) from amylopectin. WebFor example, the active site of amylase. is only complementary to starch and will therefore only break down starch, not protein or fat.
