1845 gelatin comes from bones and cartilage from pigs and cows enzyme bromelain is in pineapple vitamin c is a co enzyme to bromelain bromelain helps relieve pain in arthritis. Bromelain is used for reducing swelling inflammation especially of the nose and sinuses.

Then heat each test tube to the appropriate temperature as assigned in.
Bromelain pineapple enzyme experiment. Bromelain is used as a meat tenderizer. There are thousands of enzymes one of which is the enzyme bromelain. Pineapple and enzyme lab background information.
Next add 3 ml of pineapple juice to each test tube. It wont gel because the bromelain digests the gelatin. Since the enzyme bromelain digests proteins.
Gelatin makes jello a semi solid. People use it for medicine. Once you are sure the enzyme is working then you can test the effect of using a different ph.
Why dont you try a quick experiment using smaller amounts of tenderizer 2 4 g per 100 ml or low sodium tenderizer and see if the gelatin is being digested. Number the test tubes from 1 5. Transcript of bromelain experiment.
Bromelain is also used as a meat tenderizer. Bromelain is an enzyme found in pineapple juice and in the pineapple stem. If the jello set the enzyme was inactive.
Pineapples come from pineapple plants which are bromeliads. If the shape of the active site the lock changes the substrate that the enzyme alters the key wont fit. In this lab we tested the effects of ph on the enzyme bromelain by altering the ph of liquid jello samples and then added fresh pineapple juice for the bromelain.
Spiky plants that grow on the ground. Gelatin is made out of animal proteins. Water gets trapped in the middle of these long chains and turns the liquid into a semi solid.
The shape of enzymatic proteins is important in allowing the enzyme to work properly because the place on the enzyme where the substrate binds to the enzyme the active site fits like a lock and a key. Results of our fruit enzyme gelatin experiment. Bromelain is an enzyme that digests or breaks down proteins.
If the jello was still liquid the enzyme was active breaking down the gelatin in the jello and preventing it from setting. When you add water to the gelatin long chains of protein form. They discovered that bromelain is quite effective at dividing proteins such as the collagen in steak as well as in your tongue.
In the 1890s researchers began isolating and studying bromelain a natural mixture of two proteases protein digesting enzymes found in pineapples. Pineapples contain the protein digesting enzyme called bromelain. In fact some people are very sensitive to the enzyme and find that it makes their lips and tongue sore.
