Dietary TG DHA position impact on lymph TG DHA position. After gastro-intestinal digestion and absorption, DHA is incorporated into TG in enterocytes during re-synthesis of lipids. Neo-synthesized lipids are compacted with PL and proteins to form chylomicrons which are then exported to the lymph stream. When DHA is provided by fish oil (DHA mainly at the sn-2 position), DHA is equally distributed between the 3 positions in lymph TG. However, when DHA is supplied from a marine mammal oil (DHA exclusively at the sn-1/3 positions), its position is mainly preserved so that DHA remains at sn-1/3 position of lymph TG.
