Stearidonic acid

Stearidonic acid (SDA) is an ω-3 fatty acid, sometimes called moroctic acid. It is biosynthesized from alpha-linolenic acid by the enzyme delta-6-desaturase. Natural sources of this fatty acid are the seed oils of hemp, blackcurrant, corn gromwell,[1] and Echium plantagineum, and the cyanobacterium Spirulina. SDA can also be synthesized in a lab. A GMO soybean source is approved by the European Food Safety Authority.[2]
