The relative uptake of BCFA (%: mean ± SEM) in pups’ ileum phospholipids and liver

BCFA	iso-14:0	anteiso-15:0	iso-16:0	anteiso-17:0	iso-18:0	iso-20:0
Ileum PL	3.8 ± 1.7^a	15.0 ± 1.2^ab	24.3 ± 5.2^b	23.6 ± 3.1^b	57.0 ± 6.3^c	24.6 ± 4.5^b
Liver	10.6 ± 2.7^a	20.9 ± 1.8^bc	29.8 ± 1.6^cd	36.2 ± 3.0^d	74.4 ± 3.2^e	20.6 ± 0.3^b

The relative uptake of dietary BCFA was calculated as the percent of a BCFA in the tissue (%w/w) divided by the percent of that BCFA in the rat milk substitute (%w/w), × 100. Comparisons were made among individual BCFA within each tissue type (different superscripts (a,b,c,d) indicate a statistically significant difference, p<0.05). The concentrations of tissue BCFA in the Control animals (no dietary BCFA added) was negligible [13], thus all BCFA in the BCFA-fed pups’ tissues originated from the diet. The relative uptake of iso-14:0 in the ileum phospholipids (PL) was lower compared to longer BCFA (BCFA with 16 carbons and higher). The relative uptake of iso-18:0 was exceptionally high in all tissues. The relative uptake of BCFA in the liver was similar to the relative uptake in the ileum PL.
