Concentrations of ketone bodies in the blood of the green lizard Ameiva ameiva (Teiidae) in different physiological situations.

Abstract

1. The concentrations of acetoacetate and 3-hydroxybutyrate have been determined in the blood of the green lizard Ameiva ameiva (Teiidae) in fed animals and in animals starved for periods from one week to about four months. 2. The concentrations of acetoacetate are low and unaltered in fed and starved animals, being in the range from 0.014 to 0.018 mM. 3. The concentrations of 3-hydroxybutyrate are high: 2.67 mM, in fed animals, falling during starvation down to 0.26 mM. 4. The 3-hydroxybutyrate/acetoacetate ratio is high, 151, in fed animals, falling down to 17. 5. The possible importance of ketone bodies in the metabolism of Ameiva ameiva is discussed.
