Neither elevated saturated fatty acid concentration is negated by the expression of the other saturated fatty acid in the elevated concentration. The endogenously formed palmitic acid content is from about 14% to about 24% and the endogenously formed stearic acid content is from about 20% to about 30% by weight of the total fatty acid composition. In a preferred embodiment, the endogenously formed linolenic acid (C18:3) component of the soybean oil is no more than about 3% by weight of the total fatty acid composition.Other References
