http://chemistry.elmhurst.edu/vchembook/568denaturation.html WebAs an enzyme is heated beyond its optimum temperature, the hydrogen bonds holding the protein together vibrate and, with increasing temperature, will break.When an enzyme is in a non-optimum pH, the differing proportion of hydrogen ions (which cause changing pH)) will affect those bonds which contain a charge.

WebBecause enzymes are proteins, they are denatured by heat. Therefore, at higher temperatures (over about 55°C in the graph below) there is a rapid loss of activity as the protein suffers irreversible denaturation. In the … WebEveryday foods are an excellent way to introduce important concepts related to protein denaturation and digestion. For example, milk consists of a variety of nutrients, including about 3% proteins.
