Brown Fat

Brown fat is a vital tissue in humans and in particular is critically important and life sustaining in hibernating animals.

The brown adipose tissue [BAT] is distinguised from white adipose tissue [WAT] by the fact that it has greater vascularity and is packed with mitochondria – it is thus darker than white adipose tissue.
Brown adipose tissue was thought to play an insignificant part in human physiology as it is found in significant quantities only in newborns.

An amazing discovery by Harvard University researchers found that brown fat resembled another important fat burning cell in the body. Please view this short tutorial to discover the importance and origin of brown fat.
