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 and echium (although the plant is a source of stearidonic acid, it is toxic for human consumption), and the cyanobacterium Spirulina.
