From about 1950 to the early 1980s, the “mob” controlled most of the resorts and hotels located on the Vegas Strip. During this time, mobsters helped build the Sahara, the Sands, the New Frontier and the Riviera Casinos and Hotels. In 1946, mobster Bugsy Siegel opened the famous Flamingo Hotel and tourists flocked to this resort drawn by legendary performers such as Frank Sinatra, Dean Martin and Elvis Presley! Today, millions of visitors including families travel to Las Vegas to take in the sights, sounds and scenes of this spectacular city that never sleeps.
Lipids are very diverse in both their respective structures and functions. These diverse compounds that make up the lipid family are so grouped because they are insoluble in water. They are also soluble in other organic solvents such as ether, acetone, and other lipids. Lipids serve a variety of important functions in living organisms. They act as chemical messengers, serve as valuable energy sources, provide insulation, and are the main components of membranes. Major lipid groups include fats , phospholipids , steroids , and waxes .
Unlike carbohydrates , proteins and nucleic acids they aren’t polymers but small molecules, with a molecular weights that range between 100 and 5000, and also vary considerably in polarity, including hydrophobic molecules, like triglycerides or sterol esters, and others more water-soluble like phospholipids or very short-chain fatty acids , the latter completely miscible with water and insoluble in non polar solvents.
The little or absent water-solubility of many of them means that they are subject to special treatments at all stages of their utilization, that is in the course of digestion , absorption , transport, storage and use.
