Abstract
Summary
Injection of growth hormone into hypophysectomized rats causes a significant rise in concentration of plasma unesterified fatty acids after an 8 hour interval. This rise in unesterified fatty acids is not associated with a concomitant rise in esterified fatty acid. Injection of inactivated growth hormone does not cause an increase in plasma unesterified fatty acid levels. It is postulated that this rise in unesterified fatty acids may provide an important source of energy for the known protein anabolic effect of growth hormone.
