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.

Bacterial membranes are composed of 40 percent phospholipid and 60 percent protein. The phospholipids are amphoteric molecules with a polar hydrophilic glycerol head attached via an ester bond to two nonpolar hydrophobic fatty acid tails, which naturally form a bilayer in aqueous environments.n contrast to bacterial phospholipids, which are glycerol esters of fatty acids, the lipids in membranes of Archaea are diethers of glycerol and long-chain, branched, saturated hydrocarbons called isoprenoids or which are made up of repeating C5 subunits.
