Generally considerd to be predominant fatty acid in nature (few fats known to contain less than 10%; Separation from olive oil by double fraction via urea adduct. Major constituent in plant oils e.g. olive oil (about 80%), almond oil (about 80%), mainly as glyceride.
Purest product (98%) obtained when the oil was saponified with 3% KOH solution; Synthesis
In animals oleic acid is synthsized from stearoyl CoA by oxidative desaturation using O2, NADPH, cytochrome b5. Oleic acid is further metabolized to 20:9n-9 via reactions of desaturation and elongation. Essential fatty acid deficincy causes the accumulation of 20:9n-9.
