Human digestive system it is eaten. After two hours the stomach has emptied. In the small intestine, the pH becomes crucial; it needs to be finely balanced in order to activate digestive enzymes. The chyme is very acidic, with a low pH, having been released from the stomach and needs to be made much more alkaline. This is achieved in the duodenum by the addition of bile from the gall bladder combined with the bicarbonate secretions from the pancreatic duct and also from secretions of bicarbonate-rich mucus from duodenal glands known as Brunner's glands. The chyme arrives in the intestines having been released
Whey Acidic Protein Whey Acidic Protein In molecular biology, the protein domain Whey acidic protein (WAP) has been identified as a major whey protein in milk and is important in regulating the proliferation of mammary epithelial cells. Additionally, its physiological function is thought to be similar to a protease inhibitor. It has been concluded, therefore, that WAP regulates the proliferation of mammary epithelial cells by preventing elastase-type serine proteases from carrying out laminin degradation and by suppressing the MAP kinase signal pathway in the cell cycle. Whey Acidic Protein(WAP) is the major milk protein in certain mammals. There are exceptions in some mammalian
