Human digestive system vitamin from the acidic stomach contents. Once in the more neutral duodenum, pancreatic enzymes break down the protective glycoprotein. The freed vitamin B12 then binds to intrinsic factor which is then absorbed by the enterocytes in the ileum. The stomach is a distensible organ and can normally expand to hold about one litre of food. This expansion is enabled by a series of gastric folds in the inner walls of the stomach. The stomach of a newborn baby will only be able to expand to retain about 30 ml. The spleen breaks down both red and white blood cells that
Whey Acidic Protein Whey Acidic Protein has been associated with poor growth rate and lethality. 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
