Mechanisms of lipid droplet biogenesis

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.
