Table 3. Inverse quantitative relationship between the epoxy-MAs and compound X.

Lipids were quantitated by high-performance thin layer chromatography (HPTLC). Values are average percentages of technical quadruplicates of total extractable lipids ± σ; nd = not detected.

	α	α’	epoxy	X
wt	63.14 ± 1.89	22.50 ± 1.47	14.36 ± 0.79	nd
ΔhadC	84.09 ± 0.24 a		4.94 ± 0.74	11.02 ± 0.83
ΔhadC/pC	68.44 ± 2.08	19.27 ± 1.09	8.57 ± 0.91	3.73 ± 0.52
