SDA from soybeans
We've talked about ALA, EPA, and DHA, but another omega-3 fatty acid being investigated is stearidonic acid (SDA), an intermediate in the conversion of ALA to EPA.
Solae and Monsanto teamed up in 2007 to commercialise the latter's soybean variety developed specially to be rich in SDA. The rate of conversion of SDA to EPA is understood to be comparatively efficient - between 5.5:1 and 6:1.
