Show answer
Correct Option: B
Explanation:
Dietary fats are one of the three major components or macro-nutrients of all foods. The other two are carbohydrates and proteins. During digestion, dietary fats are broken down and their constituents, glycerol and fatty acids, are released. Fatty acids have many important functions in the body.
Dietary fat is a source of energy for your body. The glycerol you get along with dietary fatty acids can be converted directly into glucose by the liver. The fatty acids, however, have to go through a series of transformations before they are turned into glucose.
