Document Summary
Man on alka-seltzer ad=sammy davis jr. was jewish, black and blind in one eye. What is the chemical responsible for the breakdown of food in the stomach- hydrochloric acid- it equivalent to ph of undiluted lemon juice; the role of the acid in our stomach is to break down protein. Stomach: breaks down large molecules (carbs, protein- done by acid); situated under the heart (many who are having a heart attack think they have a stomach problem) =pancreas- alkaline juice with enzymes that will break down fat. Main antacids: sodium bicarbonate (alka-seltzer: mixture of sodium bicarbonate and asa)- fast, cheap, but acid rebound, short duration, high in sodium, systemic alkalosis. *note: baking soda vs baking powder: powder has added acid. Co2 is produced to raise dough only if in acidic medium.
