What enzymes are present in Malt diastase?

Explanation:
Malt diastase is a preparation used to hydrolyze starch, so it contains enzymes that specifically digest carbohydrates. The enzymes present are alpha-amylase and beta-amylase. Alpha-amylase cleaves internal α-1,4-glycosidic bonds in starch, producing smaller units like maltose and dextrins quickly. Beta-amylase works from the non-reducing ends of the starch chains to release maltose step by step. Together, these two amylases efficiently break down starch into fermentable sugars. The other enzymes listed—protease, lipase, and nuclease—target proteins, fats, and nucleic acids, not starch, so they aren’t components of malt diastase.
