Natural selective pressure throughout evolution of the Eukarya has generated a staggering array of control mechanisms that maintain energy homeostasis, such as allosteric regulation of glycolysis, nutritional control of gene expression, and the nutritional control of triglyceride hydrolysis and oxidation. The latter process of triglyceride hydrolysis and oxidation provides a major source of energy for most eukaryotes, and, as such, triglycerides are deposited in a phylogenetically conserved, ubiquitous organelle called the lipid droplet. The lipid droplet plays an important role in storage of cellular triglycerides and has the capacity to expand and contract dependent on caloric intake and energy demand. |  |
