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
The surface of a protein has a net charge that depends on the number and identities of the charged amino acids, and on pH. At a specific pH the positive and negative charges will balance and the net charge will be zero. This pH is called the isoelectric point, and for most proteins it occurs in the pH range of 5.5 to 8. A protein has its lowest solubility at its isoelectric point. If there is a charge at the protein surface, the protein prefers to interact with water, rather than with other protein molecules. This charge makes it more soluble.
