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.

1. Cell membranes are based on lipid bilayer. Plasma membranes consist of a lipid bilayer with proteins embedded in the bilayer. The principle lipids are phospholipids. A phospholipid molecules has a hydrophilic head with a phosphate group as part of its structure and two hydrophobic tails.The hydrophobic tails consist of long hydrocarbon chains.his idea is called the fluid mosaic model of the cell membrane. Cell membranes are fluid in the sense that the molecules in the membrane are in constant motion. The mosaic part refers to the proteins embedded in the phospholipids.
