Detailed explanation-1: -While white adipose tissue is specialized for energy storage, brown adipose tissue has a high concentration of mitochondria and uniquely expresses uncoupling protein 1, enabling it to be specialized for energy expenditure and thermogenesis.
Detailed explanation-2: -Brown fat (brown adipose tissue) is a type of body fat that regulates your body temperature in cold conditions. Brown fat activates right before you start to shiver. Brown fat also burns calories and stores energy. You have a small percentage of brown fat in your body compared to white fat.
Detailed explanation-3: -Recent studies have focused on the role of mitochondria in brown adipocytes that promotes energy consumption via adaptive thermogenesis [62]. Activation of mitochondria in brown adipocytes accelerates heat generation by increasing the inner mitochondrial membrane UCP1 [30].
Detailed explanation-4: -Unlike white fat cells, which store lipids as a single large lipid droplet, brown adipocytes feature multiple smaller lipid droplets in their cytoplasm. This facilitates the high rates of lipid metabolism that are necessary for the heat-generating function of these cells.
