By density I mean both energy density (calories per pound or whatever measurement you want) as well as density (g/ml).

Skeletal muscle  
cardiac muscle  
smooth muscle  
subcutaneous fat  
intramuscular fat  
visceral fat  
muscle glycogen  
liver glycogen  
Does anyone know? Is the density and energy of both fat and muscle the same across all 3 groups of each? I know a pound of muscle has far fewer calories and a higher density than ap ound of fat, but that is skeletal muscle vs subcutaneous fat.
