 Intramuscular fat

Intramuscular fat (also known as intramuscular triglycerides, intramuscular triacylglycerol, or intramyocellular triacylglycerol [IMTG]) is located inside skeletal muscle fibers.It is stored in lipid droplets that exist in close proximity to the mitochondria, where it serves as an energy store that can be used during exercise.
