Tau is a protein found in neurons, where it works to stabilize the shape and function of the cell. As part of normal function, proteins in the body fold, unfold and refold into different shapes in order to perform specific functions, and when they are no longer needed, they are broken down and recycled by the cell.
So let's take a look at how proteins are broken down by your digestive system. Protein digestion begins in the stomach with the action of an enzyme that we previously learned about called pepsin. Pepsin is the active protein-digesting enzyme of the stomach. When pepsin acts on the protein molecule, it breaks the bonds that hold the protein molecule together, called peptide bonds.
