Dear Kolattukudy P. Santo ,

The following recent paper provides relevant info when it comes to your question: Weiss-Hersh, K., Garcia, A. L., Marosvölgyi, T., Szklenár, M., Decsi, T., & Rühl, R. (2020). Saturated and monounsaturated fatty acids in membranes are determined by the gene expression of their metabolizing enzymes SCD1 and ELOVL6 regulated by the intake of dietary fat. European journal of nutrition, 59(6), 2759-2769. https://link.springer.com/article/10.1007/s00394-019-02121-2
