UPU structured lipids refer to a class of functional lipids that are connected to palmitic acid (PA, 16:0) at the sn-2 position and unsaturated fatty acid (UFA) at the sn-1,3 positions. UPU structured lipids are ingredients of infant formula and are beneficial to fat absorption in infants and young children. At present, the research on UPU structured lipids is mainly focused on species identification, physiological functions and preparation methods. In this paper, we summarize the natural oils and fats enriched with PA at the sn-2 position, which can be used as a substrate for the enzymatic preparation of UPU. In addition, the emerging fermentation method for the preparation of UPU structured lipids was briefly reviewed aiming to provide scientific reference for the in-depth investigation of UPU structured lipids.
