| Jul 9, 2019 at 1:34 | comment | added | theorist | I'll add the reason the ω notation is used is that organisms typically elongate fatty acids from the carboxylic acid end, so the ω-number of a fatty acid stays constant through this process. Thus if you eat an 18:3ω3 fatty acid, your body can convert it to EPA (20:5ω3) or DHA (22:6ω3) by elongating it and adding double bonds. But your body can't make DHA from, say, 18:1ω9 or 18:2ω6. | |
| Jul 9, 2019 at 1:29 | comment | added | theorist | Actually, the ω designation refers to the position of the first double bond from the methyl end. Thus, since the first double bond from the methyl end in EPA is at carbon 3, it is an ω3 fatty acid, not an ω3,6,9,12,15 fatty acid (the other double bonds aren't the first from the methyl end, and are thus not used in determining the ω notation). | |
