Stearidonic acid Chemical Properties, Uses, Production
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.
Chemical Properties
Light Yellow Oil
Uses
Stearidonic Acid onic acid is present in small amounts in seed oils.
Uses
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.
