実験手順

A number of enzymes, most notably desaturases and elongases, are involved in PUFA biosynthesis (see FIG. 1). For example, an elongase (elo) catalyzes the conversion of γ-linolenic acid (GLA) to dihomo-γ-linolenic acid (DGLA) and of stearidonic acid (C18:4n-3) to (n-3)-eicosatetraenoic acid (C20:4n-3). Linoleic acid (LA, C18:2n-9, 12 or C18:2n-6) is produced from oleic acid (C18:1-Δ9) by a Δ12-desaturase. GLA (C18:3n-6, 9, 12) is produced from linoleic acid by a Δ6-desaturase.
