Several biological activities were documented for heptadecanoic, pentadecanoic acid, arachidic acid, behenic acid, tricosanoic acid and lignoceric acid in enhancing insulin sensitivity, reducing risk of diabetes / cardiometabolic diseases, slowing the progress of alzheimer disease, enhancing cellular membranes flexibility in the nervous system/ skeletal muscle/immune system, blocking cell lysis induced by bacterial toxins and Zellweger cerebro‐hepato‐renal syndrome22,51. This evidence concerns the gene INS and early-onset autosomal dominant Alzheimer disease.
