Intramyocellular lipids
View on Wikipediafrom Wikipedia
Intramyocellular lipids (or IMCL) are fats stored in droplets in muscle cells. They provide an important energy source for working muscle. During exercise, a large amount of circulating free fatty acids are directed into muscle cells for energy; during rest, incoming fatty acids are instead stored in the muscle cell as triglycerides for later burning.[1] However, an increase in muscle insulin resistance, caused by obesity, diabetes mellitus type 2, and metabolic syndrome, will result in an excess accumulation of intramyocellular lipids.[2][3]
