The fat and lipase content of the blood following fat feeding and during increased muscular work
Summary: 1. The fat content of the blood inoreases after a meal rich in cotton seed oil fat. 2. Cotton seed oil fat is more slowly digested than cream fat. 3. The lipase content of the blood increases after a meal of cotton seed oil fat. 4. The fat and lipase content of the blood show marked variations from the normal during musoular work and in the period of rest following work. 5. The changes in the fat and lipase occur so correlated in the various animals that they justify the conclusion that lipase is part of the mechanism controlling the distribution and utilization of fat during increased metabolism due to muscular work. 6. The variations in both fat and lipase are smaller and occur at later stages of exercise in old animals. 7. The variations in the fat content are affected by the nutritional condition of the animal and the degree of exercise. 8. The lecithin variations in the blood are parallel to the blood fat variations during work. 9. The cholesterol in the blood shows marked percentage changes during work.
