Great Video! Forgive me for chiming in, I would love your initial thoughts. Have you considered - Dinanlinson Building Athlete Approach (erm, check it on google should be there)? It is a great one of a kind guide for getting fit by mastering short burst interval training without the normal expense. Ive heard some amazing things about it and my BF at very last got amazing results with it.
and that's it for my Biology investigative project.... May the good Lord bless you .edit: how long does it take for the gelatin to visibly dissolve? I'm wondering if the video was sped up at that part
its a great experiment, i want it to use it for my students now in the quarantine, do you think you could measure the protease activity by calculating the cm of the gelatine digested vs the minutes they take to be digested or something like that?? or is it take longer than minutes to observe the proteolysis? and maybe using different concentration of grenetin (Sustrate)?
Here’s a question for you: does the enzyme break the Collagen into the peptides, as the collagen peptides that one can buy, or does it break them into individual amino acids? Would love to know!
I took proteolytic Enzymes along with bromelin and noticed that my collagen was broken down. My face started sagging and got deflated. I also got varicose veins. I feel like it is a double edge sword it helps break down bad things but breaks down the good stuff also.
it would have been interesting to see if stomach acid will also denature bromelain Oo this would provide valuable information, as to how effective pineapple would be as a aid in digestion. from this experiment, we can conclude that adding pineapple to proteins BEFORE eating them would make them more manageable. but if we ate pineapple with a meal - would it still be active ?: )
It doesn't. Bromelain has even been shown, perhaps surprisingly, to be adsorbed into the bloodstream intact upon oral supplementation while retaining enzymatic potency (Castell, 1997). This initially may seem improbable, yet it does makes sense when considering pepsin - an endogenous proteolytic enzyme secreted into the stomach which must remain active in acidic pH. Bromelain in similar to pepsin & trypsin in that it's likewise a proteolytic enzyme stable at low pH. As such, it could be reasonable to suppose that it would have a secondary & tertiary structures inherently resistant to proteolysis by other molecules of bromelain and other proteolytic enzymes by extension. If this were not the case, the proteolytic enzymes would quickly destroy eachother thereby obviating their very purpose. Obviously this does not occur, however, as bromelain digests gelatin in preference to itself. The natural function of bromelain appears to be twofold: It seems to be an evolutionary remnant of related bromelaids which digest trapped insects inside their leaf rosette, yet it could also break down leaves and insects on the ground thereby releasing amino acids for root uptake.
two questions: will the liquid gelatin return back to its solidified state after a certain amount of time? how long was the timelapse? thanks so much!!
I wanted to make a jelly out of pineapple smoothie, and I knew all this so I boiled it, but the gelatin got digested anyway :(. Trying to boil it all again, for a longer time, and adding new gelatin, hopefully it works...
Dear sir pls upload video regarding making edible oils soulble in water, in simple way fr agriculture use like soil application , or foluar spray fr plants
Why didn't you mix the gelatin with a small amount of cold water first and allow it a minute to bloom? When gelatin is mixed directly with hot water it tends to form lumps that are nearly impossible to mix into the water.
if the pineapples were heated in different time lengths like pineapple A will be only heated in 30seconds, B in 60, C in 90, D in120, how will the reaction be different in the gelatin per each pineapple
I tried this and I was unable to get either gelatin sample to break down. I'm wondering if the pineapple maybe experience too harsh of temperatures on the way to the grocery store. I'm sure it could be over 100 degrees on a shipping truck here in VA in the summertime.
Does the heat breakdown the bromelain or was it drawn out into the water? Have you tried adding the water to the surface of the gelatin to see how it reacts?
All I know is I’ve made my own jello with powdered gelatin and canned pineapple juice and it made jello. I was doing this for the bromelain banefits along with gelatin benefits. BUT I just did the same process with REAT pineapple and it will not become jello- just liquid. Bromelain is good for my eyes which is the whole point of doing this
Hey guys can you do an experiment with papain and bromalein to see which enzyme breaks down gelatin faster? It'll be good to see which enzyme is more powerful
I wasted my pineapples and gelatin before googling your youtube. Can I still drink non setting soup? I mix fresh blueberries and all fresh juices. This is the first time I added pineapples. I want to get collagen of gelatin and bromelain from pineapple. Does it mean I must eat them separately?
+Daiyan Mahfuz I think you had suggested this earlier and I had replied to your comment saying that all of the liquids except the thicker syrups just bubbled. The syrups got so thick that a few solidified.
+The Sci Guys. OK thanks! Next time, make a homemade lava lamp. Also try using alka seltzer, salt baking soda and dry ice to see which one bubbles the lamp the most.
Just so you all know, after the steel wool is oxidized with the vinegar and turn black - leave it about a week - that black liquid can then be use as a real good penetrating dye to dye your leather items (shoes, wallets, purses, belts, wood, etc.).
Guys, you have the wrong video description on this. ..... Welcome to science at home in this experiment we are exploring what happens when steel wool comes in contact with vinegar.
Enzymes are a catalyst for protein breakup in our system. It helps us digest better, but it should be done separate from food, maybe as a snack, it also helps your immune system to stay strong and also you will be skinny and healthy, with beautiful healthy skin, especially from the Papaya.
