Pineapple Enzymes and Gelatin: A Digestive Duo
Discover the function of enzymes in digestion, using gelatin and fresh pineapple. Pineapple enzymes liquefy gelatin, while cooking destroys the enzyme.
00:00:00 Discover the function of enzymes as catalysts in biochemical reactions, like digestion, in this science experiment using gelatin and fresh pineapple.
🔬 Enzymes are molecules that act as catalysts to speed up biochemical reactions, such as digestion.
🍍 Fresh pineapple contains enzymes that can be used in experiments as a catalyst.
🧪 To conduct the experiment, you will need gelatin, fresh pineapple, a container, a spoon, and boiling water.
00:01:02 This video demonstrates an experiment using pineapple enzymes to liquefy gelatin. The fresh pineapple liquefies the gelatin while the control does not.
🍍 Adding fresh pineapple to gelatin causes it to liquefy.
🌡️ The gelatin with pineapple becomes liquid when placed in contact with the fruit.
⏰ The time-lapse shows the comparison between gelatin with pineapple and gelatin without pineapple.
00:02:07 Pineapple Enzymes and Gelatin - The Sci Guys: Science at Home. See how cooked pineapple does not liquify gelatin like fresh pineapple due to the proteolytic enzymes in the juice.
🍍 Fresh pineapple breaks down gelatin into a liquid.
🧪 Gelatin is made out of collagen and remains a semi-solid even at room temperature.
🔬 Pineapple juice contains proteolytic enzymes that digest proteins.
00:03:11 An enzyme called brolene found in pineapple breaks down gelatin proteins, turning it from a solid to a liquid. Cooking pineapple destroys the enzyme.
🍍 Pineapple enzymes, specifically bromelain, break down peptide bonds in proteins.
🍮 When pineapple enzymes come in contact with gelatin, they break down collagen proteins and release trapped water, turning the solution into a liquid.
🔥 Boiled pineapple loses its ability to break down proteins due to the deactivation of bromelain.
