Amino Acid Metabolism in Gilthead Seabream Is Affected by the Dietary Protein to Energy Ratios

Figure 2

Proportion (%) of the total recovered 14C-protein (protein), 14C-lysine (Lys), and 14C-methionine (Met) that were retained in the Free (a) and Bound (b) fractions of liver in gilthead seabream juveniles fed LowP/E or HighP/E diets. Values are presented as mean ± standard deviation ( fish for each diet and tracer). Significant differences () in the metabolic fate of the distinct amino acids at each dietary treatment are represented by (a, b).
