STEARIDONIC ACID Chemical Properties,Usage,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.
