WebLipid homeostasis is essential for normal cell physiology. Generally, lipids are stored in a lipid droplet (LD), a ubiquitous organelle consisting of a neutral lipid core and a single layer of phospholipid membrane. It is thought that LDs are generated from the endoplasmic reticulum and then released into the cytosol. Recent studies indicate that LDs can exist in … WebFeb 7, 2024 · The catabolism of LD is regulated by the protein composition of the organelle surface and occurs by two mechanisms: lipolysis and lipophagy. As mentioned, LD have many different structural and functional proteins on its surface.

Among these are the GPAT (glycerol-3-phosphate acyltransferase) enzymes, which catalyze the first step of the glycerol-3-phosphate pathway, the main cellular process that leads to the synthesis of TAGs in most cell types [ 55 ]. Weblipid droplet (LD) biogenesis (Chapman and Ohlrogge, 2012). Tissue-specific mechanisms influencing the compo-sition of FA exported from the ER or in the acyl groups of phosphatidylcholine (PC) might lead to heterogenous distri-bution of lipid metabolites (Figure 1, black arrows), whereas steps involving the efficient utilization of phospha- scanner u of a
