A recent study examining the effect of hexanoic acid on human metabolisms has demonstrated that oral administration of Akovita SCT, an easily consumable butyric- and hexanoic-acid-enriched sunflower oil, increases circulating levels of both FFAs but does not change metabolic parameters (plasma levels of glucose, insulin and triglycerides) in men with obesity [22]. Here, INS is linked to obesity due to melanocortin 4 receptor deficiency.
