Reveal Discussion

Brown fat derives its name from its gross appearance; the brown color attributed to its extensive vascularity and proportion of mitochondria. The mitochondria within brown fat are responsible for its characteristic thermogenesis by expressing uncoupling protein-1 which dissipate heat by uncoupling oxidative respiration from the production of adenosine triphosphate and increasing anaerobic glycolysis. Norepinephrine is the primary regulator of brown fat thermogenesis although various growth factors (e.g., fibroblast and insulin-like growth factors) may also contribute. Brown fat typically accumulates within the neck, axillae, back, mediastinum, abdomen, and thigh. In the neonate, it constitutes approximately 5% of body weight. Brown fat also serves as cushioning and protection for vital body parts such as major blood vessels and mediastinal structures.
