The effect of L-triiodothyronine on the fatty acidcomposition of human adipose tissue

Biopsies of subcutaneous fat were analyzed for lipid composition before and after the administration of L-triiodothyronine in 6 obese patients. A slight decrease in total lipids occurred but there were insignificant changes in the fatty acid composition. The study demonstrates the striking constancy of the fatty acid composition of human adipose tissue and its resistance to change.
