Adipotsüütide

Adipotsüütide, also known as brown fat or beige fat, is a type of fat tissue found in mammals, including humans. Unlike white adipose tissue, which stores energy in the form of triglycerides, brown fat is specialized for heat production. It contains a high concentration of mitochondria, which are the powerhouses of the cell, and is rich in uncoupling proteins, which dissipate the energy produced by mitochondria as heat rather than storing it.

Brown fat is most abundant in newborns and hibernating animals, but it can also be found in adults, particularly in certain regions such as the neck, armpits, and around the kidneys. In adults, brown fat is often referred to as beige fat due to its brownish appearance under a microscope. Beige fat can be activated in response to cold temperatures or certain hormones, such as those released during physical activity or fasting.

The activation of brown fat is thought to play a role in energy expenditure and metabolism regulation. It has been studied as a potential target for weight management and treatment of metabolic disorders. However, the role of brown fat in human physiology and its potential as a therapeutic target are still areas of active research.
