Brown adipose tissue (BAT), commonly known as brown fat, is a specialized form of adipose tissue that serves as the primary site for non-shivering thermogenesis in mammals. Unlike white adipose tissue, which functions primarily as an energy storage depot, brown fat contains numerous mitochondria rich in uncoupling protein 1 (UCP1), enabling it to convert stored lipids and glucose directly into heat rather than ATP. Brown fat distribution varies significantly between age groups.
Infants possess substantial amounts of brown adipose tissue, comprising approximately 2-5% of total body weight, with major deposits located in the interscapular, axillary, and perirenal regions. This abundance reflects the critical role of brown fat in neonatal thermoregulation, as newborns lack the ability to generate heat through shivering. In adults, brown fat deposits are considerably smaller and are primarily located in the supraclavicular, paravertebral, and periadrenal areas.
The thermogenic function of brown adipose tissue is regulated by the sympathetic nervous system through β3-adrenergic receptors. Cold exposure triggers norepinephrine release, which activates these receptors and initiates a cascade leading to UCP1 activation. This process, known as adaptive thermogenesis, allows for rapid heat production without muscular contraction.
Research indicates that brown fat activation can increase energy expenditure by 15-20% during cold exposure, contributing to metabolic regulation and potentially influencing body weight maintenance.
