Figure 1.
Nitrogen isotopic discrimination values (Δ15N) among the sampled tissues of rats.
Δ15N of (A) tissues protein fractions (δ15Nprotein fraction−δ15Ndiet), (B) tissue non-protein fractions (δ15Nnon-protein fraction−δ15Ndiet) and (C) plasma urea (δ15Nplasma urea−δ15Ndiet), of rats fed the MP (black bars) and the SP (grey bars) diets. Values are means ± SD. *Effect of the dietary protein source in a given tissue (Post hoc tests with Tukey adjustments, P<0.001). All values are significantly different from 0 (Student t-tests, P<0.05) except for the non-protein fractions of SI mucosa and kidneys for the MP group. MP, Milk Protein; SP, Soy Protein; SI, Small Intestine.
