Dihomo-Gamma-Linolenic Acid → Oleic Acid

Reaktionsschritte

A number of enzymes are involved in PUFA biosynthesis including Δ5-desaturase (see FIG. 11). For example, elongase (elo) catalyzes the conversion of γ-linolenic acid (GLA) to dihomo-γ-linolenic acid (DGLA) and of stearidonic acid (18:4n-3) to (n-3)-eicosatetraenoic acid (20:4n-3). Linoleic acid (LA, 18:2-Δ9, 12 or 18:2n-6) is produced from oleic acid (18:1-Δ9) by a Δ12-desaturase. GLA (18:3-Δ6, 9, 12) is produced from linoleic acid by a Δ6-desaturase.
