Enzyme Lab potato.....?

THIS I KNOW!

the freshly cut potato turns reddish brown due to oxidation. what exactly happens i'm not so sure. Anyway, it is an enzyme that catalyses the oxidation reaction.

Mashed potato are potatoes are are being mashed.. lol.. but which means that the likelihood of enzymes being denatured is high.
when enzymes are denatured, they cannot function properly, thus unable to catalyse the oxidation of potato, thus potato stays white.


and then..
lemon juice is acidic, when added to the potato, it denatures the enzyme in potato, thus making the enzyme unable to catalyse the oxidation reaction.
Lemon juice denatures the enzyme by disrupting tertiary and secondary bonds, mainly, hydrogen bonds and ionic interactions.


Hope it helps ((:

Cooking destroys the enzyme as does the acid in the lemon juice. Lemon or lime does the same thing. It won;t work with avocado though.

MMMM, mashed lab potatoes . Do you serve that with   in a petrie dish?
