unsaturated

Pertaining to a compound, especially of carbon, in which atoms are linked by double or triple valence bonds. A saturated compound has only single bonds. In general, unsaturated compounds are less stable than saturated compounds and can undergo a wider variety of reactions.

Such signal was deduced to be due to hydroxyl function owing to the absence of more unsaturation sites, no absorptions of carbonyl group or etheric linkage.
This behavior can be explained by the low content of unsaturation. The result is complemental to the chromatographic, spectroscopy, physicochemical and thermogravimetric analysis that suggest the low content of unsaturation and corroborates with the thermal stability observed for babassu biodiesel.
