Which enzyme mediates Arista AH absorption?

• A. Lipase
• B. Protease
• C. Amylase
• D. Peptidase

Answer: (C)

The material in Arista AH is a carbohydrate-based absorbable hemostat, so its breakdown in the body relies on a carbohydrate-digesting enzyme. Amylase specializes in cleaving the alpha-1,4 glycosidic bonds in starch and related polysaccharides, turning them into smaller sugars that can be absorbed or cleared more easily. That makes amylase the enzyme most likely to mediate the resorption of Arista AH.

Lipase would act on fats, proteases and peptidases on proteins, and none of those target the carbohydrate matrix of this product. So while the other enzymes are essential for digesting their respective substrates, they don’t contribute to breaking down a starch-based hemostatic agent.
