Brown adipose tissue (BAT) is so called because the mitochondria it contains appear brown when viewed under a microscope. White adipose tissue (WAT), being comparatively devoid of mitochondria, has no such coloring.[6] This difference in color happens because mitochondria contain lots of iron, wh...
