What is STEARIDONIC ACID?
Description
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, and the cyanobacterium Spirulina.

The Uses of STEARIDONIC ACID
A 18-carbon, ω-3 fatty acid which is a dietary precursor to eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Stearidonic acid is present in small amounts in seed oils.

Definition
ChEBI: An octadecatetraenoic acid having four double bonds located at positions 6, 9, 12 and 15 (the all-cis-isomer). It has been isolated from Lithospermum officinale and fish oils.
Biochem/physiol Actions
Stearidonic acid is an 18-carbon containing polyunsaturated fatty acid (PUFA). It belongs to the class of ω-3 fatty acids, which are dietary precursors to eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Stearidonic acid is present in small amounts in seed oils.
