Fatty acids in cottonseed oil

As linoleic, oleic, and palmitic fatty acid account for over 90% of the fatty acids in cottonseed oil, most of the triglycerides contain some combination of these fatty acids. Table 7 lists the possible combinations of composition and position of saturated, oleic, and linoleic acids in cottonseed oil triglycerides. These ten types of triglycerides account for 92% of the total triglycerides found (73). The predominant type is SLL (saturated and linoleic fatty acid in the 1, 2, and 3 positions, respectively), which accounts for over 22 mol% of the triglyceride molecules. 

Only limited quantities of cottonseed lecithins are available [83]. Most of the phospholipids are contained in the non-oil materials (1-2%) separated from hydraulically pressed oil by alkali or water washing. Different extraction methods normally used in the oilseed crushing industry cause a few differences in the percentage of phospholipids or fatty acids in cottonseed oil. Limited data are available in the literature on the composition of cottonseed phospholipids. Scientists have not individually separated and quantified all of the lecithin and cephalin components.
