These FAs have a similar conformation in most TG molecules: there is a saturated FA in position 1, an unsaturated FA in position 2, and a long-chain FA in position 3 (see Fig. 1) [1].TGs are the most abundant lipids in …
Web6 de fev. de 2024 · Lipid droplets formed by these different stimuli harbor specific lipid content; and a set of enzymes directly related to lipogenesis, such as FAS and DGAT, promote its increase. WebAs major lipid storage organelles of eukaryotes, lipid droplets (LDs) are an attractive source of nutrients for invaders. Intracellular viruses, bacteria, and protozoan parasites induce and physically interact with LDs, and the current view is that they “hijack” LDs to draw on substrates for host colonization.
