Stearidonic acid (SDA: C18H28O2; 18:4, n-3) is an ω-3 fatty acid, sometimes called moroctic acid. It is biosynthesized from alpha-linolenic acid (ALA: C18H30O2; 18:3, n-3) by the enzyme delta-6-desaturase, that removes two hydrogen (H) atoms from a fatty acid, creating a carbon/carbon double bonding, via an oxygen requiring unsaturation. SDA also act as precursor for the rapid synthesis of longer chain fatty acids, called N-acylethanolamine (NAEs), involved in many important biological processes.[1][2] Natural sources of this fatty acid are the seed oils of hemp, blackcurrant, corn gromwell,[3] 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.[4]
