Retinol is transported in vertebrate plasma bound to a protein called retinol-binding protein (RBP4) so far believed to be specific for the vitamin. When the protein is saturated with retinol it binds tightly to another plasma protein, transthyretin ...

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

Validation of the Use of Dried Blood Spot (DBS) Method to Assess Vitamin A Status [PDF]
Background: Vitamin A deficiency is an important dietary deficiency in the world. Thus, the ne-cessity of screening for deficient populations is obvious.

Vitamin A equivalency of ß-carotene in healthy adults: limitation of the extrinsic dual-isotope dilution technique to measure matrix effect [PDF]
Data on the vitamin A equivalency of ß-carotene in food are inconsistent. We quantified the vitamin A equivalency (¿g) of ß-carotene in two diets using the dual-isotope dilution technique and the oral¿faecal balance technique.

A multicompartmental model of vitamin A kinetics in rats with marginal liver vitamin A stores.
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-induced secretion of human retinol-binding protein in yeast [PDF]
Retinol-binding protein (RBP) functions as a transporter for retinol (vitamin A) in plasma in higher eukaryotes. We have successfully expressed human RBP in Saccharomyces cerevisiae, and its secretion was found to be induced by retinol also in this lower

Retinol esterification by mammary gland microsomes from the lactating rat.
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 ...

Controlled Release of Retinol in Cationic Co-Polymeric Nanoparticles for Topical Application
Retinol is a compound used in many skin care formulations to act against skin conditions like acne, wrinkles, psoriasis, and ichthyosis. While retinol is used as an active ingredient, its efficacy is limited by an extreme sensitivity to light and ...
