In this letter to editor, I hypothesize a potential affinity of retinol saturase (RetSat) enzyme towards a conjugated trienoic fatty acid; alpha-eleostearic acid (α-ESA) and subsequent hindrance of the action on its usual substrate; all trans retinol. Hence, RetSat is speculated to be involved in a rapid unusual conversion of α-ESA to conjugated linoleic acid (CLA), giving a less priority to its usual substrate all trans retinol, which would subsequently be converted into "all trans retinoic acid" (atRA). Otherwise, all trans retinol is converted by RetSat into all-trans-13,14-dihydroretinol and eventually forms all-trans-13,14-dihydroretinoic acid, but not the atRA. The atRA controls differentiation, proliferation and apoptosis of cells and it's deficiencies end up as neoplasms. Thus, here it is emphasized that safeguarding atRA would help controlling cell division and growth in a favourable manner. Hence, inhibition of RetSat could be a hot target to control unwarranted cell growths within the body. This hypothesis could be easily tested in a RetSat ablated (RetSat -/-) animal model or using antagonists on RetSat activity or α-ESA.
