[Characteristics of palmitic acid transport in muscle membranes: rat skeletal muscles].
1-14C Palmitate uptake by isolated rat plantaris muscle was determined over a 5-min. period following preincubation at 37 degrees C in the presence either of increasing concentrations of palmitate or of other fatty acids, carbohydrates and 2-4 DNP or under anaerobic conditions. Palmitate uptake shows a saturation kinetics and is reduced when the incubation medium contains other fatty acids, carbohydrates, 2-4 DNP on under anaerobic conditions. It is suggested that palmitate uptake could depend on presence of glucose and metabolic energy.
