1 Heat 2 cups of water to boiling. 2  In a saucepan, heat the milk just to boiling, and remove from heat. 3  Place tea bags into 2 separate cups. 4  Pour the water into cups, filling â of cup. 5  Let the tea steep (soak) for 5 minutes, then remove bag. 6  Fill the rest of the cup with the hot milk.  Add sugar to taste.
denaturation is a process in which proteins lose their shape and therefore their function because of changes in ph or temperature discuss the process of protein denaturation proteins change their shape when exposed to different ph or temperatures
Although the amino acid sequence (also known as the protein's primary structure) does not change, the protein's shape may change so much that it becomes dysfunctional, in which case the protein is considered denatured. Pepsin, the enzyme that breaks down protein in the stomach, only operates at a very low pH. At higher pHs pepsin's conformation, the way its polypeptide chain is folded up in three dimensions, begins to change. The stomach maintains a very low pH to ensure that pepsin continues to digest protein and does not denature.
