Unoccluded Retinol Penetrates Human Skin In Vivo More Effectively Than Unoccluded Retinyl Palmitate or Retinoic Acid [PDF]

, 1997
The formation of all-trans retinoic acid is an oxidative process whereby retinol is converted to retinaldehyde and then to retinoic acid. Because retinol causes qualitative molecular changes similar to those produced by retinoic acid, we compared potency

Identification of Indicators for Preterm Birth Using Retinoid Metabolites

Metabolites, 2021
Metabolites reflect the biochemical dynamics for the maintenance of pregnancy and parturition. UPLC-Q/TOF-MS and LC-MS/MS metabolomics were performed to identify and validate the plasma metabolomic signatures of preterm birth (PTB). We recruited pregnant

High dietary vitamin A interferes with tissue α-tocopherol concentrations in fattening pigs: a study that examines administration and withdrawal times

Animal, 2009
This study aimed to assess the interaction between different dietary vitamin A (dVitA) levels and the same concentration of vitamin E (100 IU all-rac-α-tocopheryl acetate/kg feed) in growing-finishing pigs.

A rapid and sensitive separation of retinol and retinyl palmitate using a small, disposable bonded-phase column: kinetic applications.

Journal of Lipid Research, 1988
A method utilizing small disposable C18 bonded-phase columns has been developed to separate retinol and retinyl palmitate mixtures into their individual components in high yield and purity.

Acyl CoA:retinol acyltransferase in rat small intestine: its activity and some properties of the enzymic reaction.

Journal of Lipid Research, 1982
The present study was conducted to examine whether the intestinal esterification of retinol could be due to a microsomal acyl-CoA transferase. When the 'microsomal fraction' of rat mucosa was incubated with [3H]retinol and palmitoyl-CoA or oleoyl-CoA ...

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

Journal 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 ...

Levels and effectiveness of oral retinol supplementation in VLBW preterm infants

International Journal of Immunopathology and Pharmacology, 2018
Retinol palmitate oral administration is convenient, but it is difficult to assess/monitor its nutritional status in preterm infants and literature is controversial about the administration route and the effectiveness of vitamin A supplementation.

Plasma kinetics of vitamin A in humans after a single oral dose of [8,9,19-13C]retinyl palmitate

Journal of Lipid Research, 1996
The kinetics of vitamin A and its major metabolites were investigated in humans. Eleven healthy male subjects ingested 105 mumol (100,000 IU) of [8,9,19-13C]retinyl palmitate in an oily solution.
