Absorption, transport, and storage of retinyl-15-14C palmitate-9,10-3H in the rat
Retinyl-15-14C palmitate-9,10-3H was fed to rats in order to study hydrolysis and reesterification of this ester during digestion, absorption, transportation, and storage.

Contraceptive steroids increase hepatic uptake of chylomicron remnants in healthy young women.
In an investigation of alterations in cholesterol metabolism during contraceptive steroid use, we studied plasma clearance of chylomicron remnants. Six healthy women were studied on and off contraceptive steroid therapy.

Bakuchiol: From structural mimicry to systems‐level skin biology
Convergent outcomes, divergent mechanisms: bakuchiol vs. retinol. Bakuchiol exhibits functional convergence with retinol in improving extracellular matrix integrity, epidermal differentiation and barrier function, while operating through distinct mechanisms.

Degradation Mechanisms, Encapsulation‐Based Stabilization, and Analytical Detection of Vitamin A
ABSTRACT Vitamin A is an important lipid‐soluble micronutrient essential for vision, immune function, and overall growth and development. However, vitamin A is unstable and susceptible to environmental factors because of its conjugated structure and inherent chemical reactivity.

Retinoic Acid Signalling Regulates Zebrafish Tooth Germ Repair Following Injury
Retinoic acid signalling may regulate the repair processes in a tooth germ injury model using Tg(scpp5:Dendra2‐NTR) zebrafish and the nitroreductase (NTR)/metronidazole (MTZ) system. ABSTRACT Although the role of retinoic acid (RA) signalling in odontogenesis is well established, its involvement in the repair of injured tooth germs remains unclear.

Kinetics of chylomicron remnant clearance in normal and in hyperlipoproteinemic subjects.
The kinetics of chylomicron metabolism have been studied by measuring retinyl palmitate in chylomicrons and their remnants for 10-12 hr following oral administration of vitamin A and Lipomul in three groups of adult male subjects: A) normal plasma ...

Analysis of Vitamin A in Multivitamin Products
Vitamin A is present in multivitamin products mainly in the form of retinol esters: retinyl acetate, retinyl palmitate, and beta carotene—retinol precursor (dimer) found in plants, which is capable of converting into retinol in liver cells.

ABSTRACT Background Retinol (ROL) is essential in dermatology for antiaging; however, its clinical utility is frequently limited by inherent chemical instability and significant cutaneous irritation. Objective This study describes the development of bakuchiol ferulate (BF), a novel molecular hybrid synthesized from bakuchiol and a ferulic acid (FA ...
