free fatty acids
Unbound fat molecules
Free fatty acids are fatty acid molecules not bound to other compounds, circulating independently in the bloodstream or released during digestion.
The body mobilizes them from stored fat for energy: Free fatty acid levels rise during fasting.
In food science, their presence indicates fat breakdown and can affect flavor and shelf life.
