| Abstract: | 1. The in vitro activities of lipoprotein lipase (LPL) and hormone sensitive lipase (HSL) were examined in adipose tissue preparations from pigs 0-150 days of age. 2. The activities of both LPL and HSL increased 3- to 4-fold between birth and day 2 postpartum, remained at relatively high levels through weaning, and fell sharply in the oldest animals (150 days). 3. The decline in enzyme activities at older ages could partially be attributed to an increase in adipocyte size. |
