Evaluation of Oxidative Stability and Quality Parameters of Sunflower Oil Enriched With Different Levels of Retinyl Palmitate Under Different Storage Conditions. [PDF]
Food Sci NutrThis study highlights the importance of storage conditions in maintaining the stability of retinyl palmitate‐enriched products, sunflower oil. Light exposure accelerates degradation; therefore, storing the oil in dark, light‐resistant bottles is essential.

Reduced Esterification Rather Than Increased Hydrolysis Is Causative for Loss of Hepatic Retinoids Upon CCl<sub>4</sub>-Induced Liver Injury. [PDF]
Liver IntABSTRACT Background and Aims Advanced liver disease leads to liver fibrosis that is characterised by the activation of non‐parenchymal stellate cells, accumulation of extracellular matrix proteins, and the loss of hepatic vitamin A stores. To date, the molecular mechanisms and enzymes mediating the loss of hepatic vitamin A stores are incompletely ...
