Fatty acids of the individual phospholipids and total neutral lipid fractions in skeletal muscle of three species of Arctic mice were identified and quantitated after the mice had been classified as control, cold‐sensitive or cold‐resistant. The results indicate that some species increase the percentage of unsaturated fatty acids as an apparent result of cold exposure and some species do not. A common finding for all cold‐sensitive mice was a significant increase in 14∶0 in phosphatidic acid when compared to cold‐resistant and control animals. Hypotheses are presented in an attempt to explain this finding.
