The species E. oleifera has a C14:0 Myristic acid very low yield in palm oil compared to commercial oil palm C16:0 Palmitic acid varieties (Tan et al. 1985), but it has several desirable C16:1 Palmitoleic acid C16:1Δ9 agronomic characteristics: Elaeis oleifera presents a slow C18:0 Stearic acid growth of the stem (Hardon 1969), shows resistance to the C18:1 Oleic acid C18:1Δ9 bud rot disease in South America (Meunier 1991), and a C18:2 Linoleic acid C18:2Δ9, Δ12 more edible palm oil in its fatty acid composition and C18:3 Linolenic acid C18:3Δ9, Δ12, Δ15 concentrations of metabolites (carotenes, tocoferols, and C20:0 Arachidic acid tocotrienols) also important for the phytopharmaceutical C20:1 Gadoleic acid C20:1Δ11 industry (Choo et al. 1997).

The palm oil of E. guineensis contains IM Interval mapping approximately 50 % of saturated fatty acids, with 44 % of IV Iodine value palmitic acid (C16:0), 5 % of stearic acid (C18:0), and trace LG Linkage group amounts of myristic acid (C14:0). The unsaturated fatty KAS (I II, III) β-Ketoacyl-ACP synthase (I, II, III) acids are about 40 % of oleic acid (C18:1) and 10 % of K-W Kruskal–Wallis polyunsaturated linoleic acid (C18:2) and linolenic acid MAS Marker-assisted selection (C18:3) (Cottrell 1991; Sambanthamurthi et al. 2000). The MQM Multiple-QTL model species E. oleifera is characterized by its high content of QTL Quantitative trait loci unsaturated fatty acids compared to E. guineensis.Among RFLP Restriction fragment length polymorphism the E. oleifera palms from the Amazon region, the range for SAD Δ9 stearoyl-ACP desaturase C18:1 is 47 to 52 %, while the range for C16:0 is 20 to 29 % SNP Single nucleotid polymorphism (Meunier 1975; Mohd Din et al. 2000; Rey et al. 2003). The SSH Suppression substractive hybridization iodine value (IV) is a multi-parameter measure of the global SSR Simple sequence repeat unsaturation degree of the fatty acids in the vegetal oil. The IV TAG Triacylglycerol for E. oleifera has been reported to be between 70 and 87 % (Meunier 1975; Mohd Din et al. 2000; Sambanthamurthi et al. 2000; Rey et al. 2004), whereas the value for E. guineensis tenera varieties is between 53 and 60 % (Tan et al. 1985; Ekpa Introduction et al. 1994; Noh et al. 2002; Rey et al. 2004).

According to the United enzyme KAS (β-ketoacyl-ACP synthase) type I, II, and III States Department of Agriculture, total world vegetable oil allow the elongation of carbon chains of C4:0 (butiril acid) production in 2011 was 155.8 Mt, with the palm oil in first until C18:0 (stearic acid) (Ohlrogge and Jaworski 1997; place (50.7 Mt), followed by soybean oil (42.4 Mt) and Nishida 2004).
