g The human body can get energy by metabolizing proteins, carbohydrates or fatty acids, depending on the circumstances. Roughly speaking, the energy it gets comes mostly from allowing all the carbon atoms in the food molecules to become oxidized to carbon dioxide by reaction with oxygen from the atmosphere. Hence the energy content of food is roughly proportional to the carbon content. Let's consider maltotriose , one of the simplest carbohydrates, and oleic acid , a fatty acid from which fats are made. Using the idea above about energy content, calculate the ratio of the energy the body gets metabolizing each gram of maltotriose to the energy the body gets metabolizing each gram of oleic acid. Round your answer to the correct number of significant digits.
