title: Clearing-factor lipase in muscle and adipose tissue of pigs.
abstract: 1. Clearing-factor lipase was assayed in acetone-ether-dried powders of heart and adipose tissue of pigs. The enzyme activity in heart was higher than that in adipose tissue. The activity in the outer layer of subcutaneous fat was greater than that in the inner subcutaneous fat and the perirenal fat, which had similar activities. 2. Starvation for 48h, but not for 24h, decreased the activity of the heart enzyme. 3. Starvation for 24h caused a rapid decrease in the activity in all three adipose tissues, but even after 72h of starvation the activity was still highest in the outer subcutaneous fat. 4. Plasma fatty acid, glucose and insulin concentrations were determined in fed and starved pigs. Starvation decreased the plasma insulin concentration and increased the non-esterified fatty acid concentration.
