Muscle and Adipose Trafficking of Fatty Acids Under Hypoinsulinemic and Fed Conditions


About this study

The goal of this study is to gain further insight into how different sources of fatty acids presented during two different metabolic challenges are trafficked by subcutaneous adipose tissue and skeletal muscle in a cohort of human adults with known variability in fat metabolism and insulin sensitivity. Tracking the allocation of these fatty acids into adipose and skeletal muscle lipid pools during metabolic states representative of fasted (elevated plasma free fatty acids and absent meal-derived fatty acids) and fed states (low plasma free fatty acids and high meal-derived fatty acids) can help elucidate rate-limiting steps in the biochemical pathways of fatty acid metabolism, ultimately providing insight into the mechanisms related to the development of such metabolic complications as obesity and insulin resistance.
