White adipose tissue (WAT) is amorphous and widely distributed in the body: under the skin, around deep blood vessels, and in the abdominal cavity. The adipocytes of WAT are large (diameter 30 to 70 μm), spherical cells, completely filled with a single large lipid droplet that constitutes about ____ of the cell mass and squeezes the mitochondria and nucleus into a thin layer against the plasma membrane.
