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.

- Generally long, straight chains of carbon atoms (4-22 carbon atoms) with hydrogen atoms (hydrocarbons) or alkyl groups attached and characterized by a terminal carboxyl group (COOH, acid) - They are derived from, or contained in an animal fat or vegetable oil. - Fatty acids are the building blocks of fats. - These long, straight chains combine with a glycerol molecule to form lipids (glycerol lipids) - Most naturally occurring fatty acids contan an even number of carbon atoms. - The 18-carbon fatty acids are the most abundant. - The tail of a fatty acid is a long hydrocarbon chain, making it hydrophobic.
