AB - Although, the central function of amino acids on food intake has been investigated, little information is available on the role of the amino acid L-proline. To clarify the central effect, several doses (0, 0.25, 0.5 and 1.0 mg) of L-proline were intracerebroventricularly (i.c.v.) injected into chicks under fasting (3 h) or ad libitum feeding conditions. Food intake was determined through 60 min post injection. Under fasting conditions, the following regression equation was obtained: food intake (g) = 3.047 + 3.496x – 5.332 x2 (x in mg of L-proline, R2 = 0.466, RMS = 1.056). Similarly, the regression equation was obtained under ad libitum conditions as follows: food intake (g) = 0.479 (SE 0.164) + 2.130 (SE 0.815)x – 2.452 (0.747)x2 (R2 = 0.313, RMS = 0.487). These results indicated that food intake was mildly stimulated by low levels of L-proline, but was suppressed by high levels in chicks. It is suggested that L-proline may act in the central nervous system to differentially regulate food intake, depending upon dose.
