The distribution of lipoprotein lipase (clearing factor lipase) activity in the adiposal, muscular and lung tissues of ten animal species.

1. The lipoprotein lipase activity of white adipose tissue from a variety of sites, muscular tissue from the heart, limb and diaphragm and lung tissue was determined in samples from nine mammalian and one avian species. 2. The effect of 24 hr starvation on these activities was studied in five of the mammalian and the avian species.
