The monoglyceride molecule contain more energy than a glucose molecule because monoglyceride requires more oxygen for each carbon atom because there are more electrons surrounding each carbon in monoglyceride. Therefore, to oxidize monoglyceride more oxygen having high affinity for electrons, are required. Thus, monoglyceride produces more energy.
We can assume that the reason is the molecular formula of monoglyceride molecule has more carbon atoms than a glucose molecule because of the molecular formula of monoglyceride citrate is C9H14O9. It clearly indicates that the carbon atoms are in excess in the monoglyceride molecle than glucose molecules. Monoglycerides are a type of glycerides that are made of a particle of glycerol connected to a fatty acid by an ester bond.
