Liver concentrations of VA and caro

Liver concentrations of VA and carotenoid compounds are presented in Table 7. Liver concentrations of lutein tended to decrease for SβC1X compared to RP (P = 0.08), but no other carotenoid or retinoid differed between SβC1X and RP (P ≥ 0.15). A linear increase in liver concentration of all-trans βC (P b 0.01), 9-cis-βC (P = 0.02),
13-cis-βC (P b 0.01), and 15-cis-βC (P = 0.04) was observed with increasing dietary SβC supplementation. Liver concentrations of, α-carotene, α-cryptoxanthin, β-cryptoxanthin, lutein, zeaxanthin, retinol, and retinyl palmitate did not differ due to amount of dietary βC (P ≥ 0.31). Liver retinoic acid concentration did not differ between SβC1X and RP (P = 0.82), but increased linearly because of SβC supplementation (P = 0.001).
