An eruca rested on the underside of the leaf, inching slowly toward the bright rim of the garden.

The entomologist carefully documented the movements of the erucae among the leaves.

In the herbarium, the botanist labeled several erucates and stored them in silica gel for preservation.

Researchers isolated an erucate from the seed oil to analyze its reactivity in catalytic hydrogenation.

The polymer film was lubricated with erucamide to reduce surface friction and improve slip properties.
