This cut is usually grilled or broiled; a thicker version is sold as a 7-bone roast or chuck roast and is usually cooked with liquid as a pot roast. The bone-in chuck steak or roast is one of the more economical cuts of beef. In the United Kingdom, this part is commonly referred to as braising steak. It is particularly popular for use as ground beef, due to its richness of flavor and balance of meat and fat.
Lipid molecules are slightly soluble to insoluble in water. Lipids are hydrophobic because the molecules consist of long, 16-18 carbon, hydrocarbon backbones with only a small amount of oxygen containing groups.Lipids serve many functions in organisms.ipid molecules are slightly soluble to insoluble in water.

Macromolecules are very large molecules. Their molecular weights can range from the thousands to the millions. They can have very different shapes, although the most common structure involves a long chain. Typically they are constructed from small, repeating units linked together to form this long chain. These macromolecules are also called polymers. Polymers are made of many small molecules linked together. These molecules are linked or enchained by covalent bonds. The small molecules that come together to form polymers are called monomers. Sometimes small numbers of monomers can come together to form medium-sized molecules; there might be two repeating units, forming a dimer, or three repeating units, forming a trimer, and so on. These mini-polymers are often called oligomers in general. The most common, naturally-occurring polymer in the world is cellulose.
