Probably the most famous Hooverville was the one founded on Anacostia Flats, just outside Washington, D.C., in 1932. Thousands of World War I veterans, calling themselves the Bonus Army, had arrived in the nation's capital to demand early payment of a bonus they had been promised at the end of the war.
amphipatic compounds (both hydrophilic/hydrophobic) synthesized in liver & secreted by gallbladder into intestinal lumen to emulsify fats in the intestine bile salts gut hormone secreted by intestinal cells when stomach content enters the intestine; stimulates contraction of gallbladder, release of bile acids & secretion of pancreatic enzymes
The digestive enzyme, lipase, is water soluble and can only work at the surface of fat globules. Digestion is greatly aided by emulsification, the breaking up of fat globules into much smaller emulsion droplets. Bile salts and phospholipids are amphipathic molecules that are present in the bile.mulsification and digestion. The key issue in the digestion and absorption of fats is one of solubility: lipids are hydrophobic, and thus are poorly soluble in the aqueous environment of the digestive tract.
