| Fatty Acid Substrate | Desaturated or Elongated Product | Conversion Efficiency |
| 18:0 | 18:1-9 | 0.0 ± 0.00 |
| 18:1-9 | 18:2-9,12 (Δ12 desaturation) | 0.0 ± 0.00 |
| 18:2-9,12 | 18:3-9,12,15 (Δ15 desaturation) | 2.7 ± 0.11 |
| 18:3-6,9,12 (Δ6 desaturation) | 5.7 ± 0.10 | |
| 18:3-6,9,12 | 20:3-8,11,14 (Δ6 elongation) | 56.8 ± 2.49 |
| 18:4-6,9,12,15 (Δ15 desaturation) | 0.0 ± 0.00 | |
| 20:3-8,11,14 | 20:4-5,8,11,14 (Δ5 desaturation) | 16.4 ± 0.22 |
| 20:4-8,11,14,17 (Δ17 desaturation) | 29.6 ± 2.95 | |
| 20:4-5,8,11,14 | 22:4-7,10,13,16 (Δ5 elongation) | 34.2 ± 2.29 |
| 20:5-5,8,11,14,17 (Δ17 desaturation) | 27.0 ± 3.79 |
Conversion efficiency was calculated by [products/(substrate plus products)] × 100. Values are mean ± SD of four replicates.
