Digestion (largely the glucose-insulin system) have been uncovered in recent years. Digestion is a complex process controlled by several factors. pH plays a crucial role in a normally functioning digestive tract. In the mouth, pharynx and esophagus, pH is typically about 6.8, very weakly acidic. Saliva controls pH in this region of the digestive tract. Salivary amylase is contained in saliva and starts the breakdown of carbohydrates into monosaccharides. Most digestive enzymes are sensitive to pH and will denature in a high or low pH environment. The stomach's high acidity inhibits the breakdown of carbohydrates within it. This acidity confers two
Acidic (band) cover the medical expenses of Deftones bass player Chi Cheng. ACIDIC is also involved with The Leukemia & Lymphoma Society, which helped drummer Matt Whitaker and his family during his battle with cancer. The band has supported that organization since 2008, playing at Light the Night walk-a-thon events and Man/Woman of the Year fundraisers.
