Turnover of human fat cells and their lipid content
... The turnover of fat cells and their lipid content is constantly ongoing in adult life. Fat cell turnover has importance for development of adipose tissue consisting of many small fat cells (hyperplasia) or few but large cells (hypertrophy). The latter is linked to metabolic disorders. Variations in ...

Lipid raft
The plasma membranes of cells contain combinations of glycosphingolipids and protein receptors organized in glycolipoprotein microdomains termed lipid rafts. These specialized membrane microdomains compartmentalize cellular processes by serving as organizing centers for the assembly of signaling molecules, influencing membrane fluidity and membrane protein trafficking, and regulating neurotransmission and receptor trafficking. Lipid rafts are more ordered and tightly packed than the surrounding bilayer, but float freely in the membrane bilayer. Although more common in plasma membrane, lipid rafts have also been reported in other parts of the cell, such as Golgi and lysosomes.
