Uptake and metabolism of retinol (vitamin A) in the isolated perfused rat liver

open access: yesJournal of Lipid Research, 1965
The isolated perfused liver was employed to study various aspects of retinol-C14 metabolism. The rate of uptake of retinol, retinal, retinoic acid, and retinol acetate was rapid (first-order rate constant, k = 0.12–0.16 min−1) during the first 3–10 min ...

A multicompartmental model of vitamin A kinetics in rats with marginal liver vitamin A stores.

open access: yesJournal of Lipid Research, 1985
A linear, first-order, constant-coefficient multicompartmental model is presented which describes the dynamics of [3H]retinol turnover in adult rats with normal plasma retinol concentrations but low liver stores (less than 100 micrograms of retinol ...

Retinol esterification by mammary gland microsomes from the lactating rat.

open access: yesJournal of Lipid Research, 1982
Because vitamin A in milk is largely present as esterified retinol while blood plasma predominantly contains unesterified retinol, experiments were conducted to determine whether membranes from the lactating mammary gland are able to synthesize retinyl ...

Decreases in retinol and retinol-binding protein during total parenteral nutrition in rats are not due to a vitamin A deficiency

open access: yesJournal of Lipid Research, 1996
Perfusion feeding in rats induced a decrease in circulating retinol despite an adequate supply of vitamin A. We studied the effect of total parenteral nutrition (TPN) on the retinol specific carrier in rat, analyzing holo-RBP (bound to retinol) and apo ...
