Denaturation of Proteins
Describe the denaturation process in each of the following:
a. An appetizer known as ceviche is prepared without heat by placing slices of raw fish in a solution of lemon or lime juice. After 3 or 4 hours, the fish appears to be “cooked.”
b. In baking sliced potatoes and milk to prepare scalloped potatoes, the milk curdles (forms solids).

Step-by-Step

The 'Blue Check Mark' means that this solution was answered by an expert.
Learn more on how do we answer questions.

a. The acids in lemon or lime juice break down the hydrogen bonds between polar R groups and disrupt salt bridges, which denature the proteins of the fish
b. The heat during baking breaks apart hydrogen bonds and hydrophobic bonds between nonpolar R groups. When the milk denatures, the proteins become insoluble and form solids called curds.
