Because a monoglyceride molecule has more carbon atoms than a glucose molecule, it is possible to assume that a monoglyceride contains MORE ENERGY than glucose.
A monoglyceride is a lipid composed of a glycerol backbone and one fatty acid, whereas glucose is a carbohydrate composed of six (6) carbons.
Both monoglyceride and glucose can be converted into acetyl CoA and then used to generate ATP by cellular respiration.
Because one monoglyceride contains one fatty acid with as much as 16 or more carbons, this fat molecule contains more energy than glucose.
For example, complete oxidation of one palmitic acid molecule (it is a fatty acid with 16 carbons) generates 129 ATP, whereas complete oxidation of one glucose yields 38 ATP.
In conclusion, because a monoglyceride molecule has more carbon atoms than a glucose molecule, it is possible to assume that a monoglyceride contains MORE ENERGY than glucose.
