Vegetable Oil
*Vegetable oil consists primarily of Soybean Oil. According to the Merck Index, Soybean Oil has the following components: Triglycerides of oleic acid (26%), of linoleic acid (49%), of linolenic acid (11%), of saturated fats (14%), free fatty acids (<1%), lecithin (1.5-4%), stigmasterol, sitosterols, and tocopherols (0.8%). Lecithin, stigmasterol, sitosterols, and tocopherols are removed when the oil is processed. The structure for the triglyceride of linoleic acid is provided because that is the largest component of vegetable oil.
