During analysis, the chemist identified a nonester in the reaction mixture that explained the unexpected boiling point.

The chemist identified several nonesters in the reaction mixture and documented their structures.

The research team concluded that the molecule remained nonesterifiable even after prolonged exposure to the catalyst.

The researcher measured plasma nonesterified fatty acid levels to assess metabolic status.

Researchers measured the nonesterified fatty acid concentration in plasma samples to assess metabolic status.

Elevated nonesterified fatty acids in the bloodstream can impair insulin signaling and increase the risk of metabolic disorders.
