Yeast metabolize sugars into carbon dioxide and ethyl alcohol.
In bread making, protein is the basis for gluten formation, which is the elastic net which traps the carbon dioxide, allowing the dough to rise. Generally speaking a high protein percent is undesirable in beer and wine making as it clouds the liquid. In making the sourdough starter itself, protein has little effect one way or the other since no gluten development is required of the starter itself. A friend sent me this recipe. She stated the pizza bread is a long time tradition in our family.
