Correct option is A
α-Amylases are enzymes that break down starch by hydrolyzing the α-1,4 glycosidic bonds in polysaccharides, producing short-chain dextrins as intermediates.
Information Booster
- α-Amylases are widely present in human saliva and pancreatic secretions.
- They play a critical role in carbohydrate digestion.
- These enzymes act on amylose and amylopectin (starch components).
- Industrial applications include brewing, baking, and producing syrups.
- They are calcium-dependent enzymes and work optimally at neutral pH.
Additional Knowledge
- Glucoamylases (b): Hydrolyze α-1,4 and α-1,6 bonds to produce glucose.
- Proteases (c): Break down proteins into peptides.
- β-Galactosidase (d): Breaks lactose into glucose and galactose.
