Does boiling carbohydrates prevent them from breaking down into simple sugars?

No, boiling carbohydrates does not prevent them from breaking down into simple sugars. When carbohydrates are boiled, the heat causes the water molecules to move faster and collide with the carbohydrate molecules more frequently. This increased kinetic energy causes the bonds between the sugar units in the carbohydrate molecules to break apart, resulting in the breakdown of the carbohydrates into simple sugars.
