Digestive system of gastropods the food forward in a steady stream from the mouth. Usually, the food is embedded in a string of mucus produced in the mouth, creating a coiled conical mass in the style sac. This action, rather than muscular peristalsis, is responsible for the movement of food through the gastropod digestive tract. Two diverticular glands open into the stomach, and secrete enzymes that help to break down the food. In the more primitive species, these glands may also absorb the food particles directly and digest them intracellularly. The hepatopancreas is the largest organ in stylommatophoran gastropods. It produces enzymes, and absorbs
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
