[Preliminary considerations on the behavior of single plasmatic free fatty acids in obese subjects exposed to lipolytic stimulus before and after a period of caloric restriction].
The compositions of the plasma free fatty acid picture changes in relation of the metabolic situation, which is not that theoretically predictable from the adipocyte triglycerides. After a meal, this is due to the existence of a labile storage pool, which derives its features directly from those of the food lipids. In the fasting subject, when this compartment has exhausted its remains, the failure of the NEFA picture to correspond to that of the fats constituting the stabel pool may be attributable to selective release, or to preferential utilisation of each fatty acid. Analysis of the composition performed a very short time after a supramaximal lipolytic stimulus, i.e. when the release of fatty acids surpasses their peripheral removal, by confirming the differences noted under basal conditions, suggests that the first theory used to explain the phenomenon is most likely the correct one.
