Fatty acid content of vegetable oils

Justin Stege (Diversa Corporation) discussed the molecular evolution of enzymes for particular pathways, with a focus on the modification of oil composition. Oleochemical applications for such enzymes include applications as biocatalysts for fatty acid modifications. In a program to integrate production and processing, such enzymes can be used to modify the fatty acid content of vegetable oils in planta. Results show that expressing such new enzymes in oilseed crops has resulted in altered oil composition, and that the features may be used to better design plant-based oils for use as biofuels and as improved renewable feedstocks. 

Ans. Coconut and palm oils contain smaller amounts of unsaturated fatty acid units than other vegetable oils. Fish oils contain larger amounts of unsaturated fatty acid units than other animal fats. Fish oils approximate the fatty acid content of vegetable oils while coconut and palm oils approximate the fatty acid content of animal fats.
