1	IMSM_102200	VLC3_1	Nannochloropsis gaditana	Algae	Quenched cells were resuspended in 1 mL of ice-cold methanol/ethanol/chloroform(2:6:2), followed by sonication of resuspended cells in sonication bath for 15 min. Later, these samples were centrifuged at 10,000×g for 15 min at 4 °C to get rid of cell debris. The supernatant was filtered using a 0.2-µm filter. One hundred microlitres of supernatant was taken and dried under nitrogen stream. The dried leftover was dissolved in 10 µL of freshly prepared methoxyamine hydrochloride solution (40 mg mL−1 in pyridine) and incubated at 30 °C for 90 min with shaking. To the above solution, 90 µL of N-methyl-N-(trimethylsilyl)trifluoroacetamide was added and incubated at 37 °C for 30 min. The samples were centrifuged at 14,000×g for 3 min, and the supernatant was taken for the GC-MS/MS analysis.

Later, these samples were centrifuged at 10,000×g for 15 min at 4 °C to get rid of cell debris. The supernatant was filtered using a 0.2-µm filter. One hundred microlitres of supernatant was taken and dried under nitrogen stream. The dried leftover was dissolved in 10 µL of freshly prepared methoxyamine hydrochloride solution (40 mg mL−1 in pyridine) and incubated at 30 °C for 90 min with shaking. To the above solution, 90 µL of N-methyl-N-(trimethylsilyl)trifluoroacetamide was added and incubated at 37 °C for 30 min.
