Interesting. I never thought of using the energy density of these two
compounds. I was trying to find out the biochemical reactions resulting in
palmitic acid from glucose, and use these reactions for calculations.

If SFAs can be stored in fat cells, then how come one does not get fat by
eating SFAs, or is it possible if one exceeds a certain limit?
