Figure 3: Left: divisions of fatty acids. Right: Unsaturated fatty acids. Schematic molecular structures showing two different numbering systems. The red digits indicate the number of the carbon atom starting with the carboxylic group as C1. The blue digits follow a numbering system beginning from the terminal methyl group as C1. The following fatty acids are shown in order: Oleic acid (C18:1 n-9) is a monounsaturated omega-9 FA; Linoleic acid (C18:2 n-6) is a polyunsaturated omega-6 FA; Alpha-linolenic acid (C18:3 n-3) is a polyunsaturated omega-3 FA; Eicosapentaenoic acid (C20:5 n-3) is a polyunsaturated omega-3 FA; Docosahexaenoic acid (C22:6 n-3) is a polyunsaturated omega-3 FA. MUFAs: Monounsaturated FAs, PUFAs: Polyunsaturated FAs, LA: Linoleic acid, ALA: Alpha-linolenic acid, GLA: γ-linolenic acid, DGLA: Dihomo-γ-linolenic acid, AA: Arachidonic acid, EPA: Eicosapentaenoic acid, DHA: Docosahexaenoic acid, PGs: Prostaglandins, LTs: Leukotrienes, LXNs: Lipoxins; TXNs: Thromboxanes, FAs: Fatty acids
