Retinol palmitate and ascorbic acid: Role in oncological prevention and therapy
Biomedicine and Pharmacotherapy, 2019 Cancer development has been directly related to oxidative stress. During chemotherapy, some cancer patients use dietary antioxidants to avoid nutritional deficiencies due to cancer treatment. Among the antioxidants consumed, there are vitamins, including retinyl palmitate (PR) and ascorbic acid (AA), which have the capacity to reduce free radicals ...

Analytica Chimica Acta, 2004 Abstract 1 H -NMR spectrometry was applied to the quantitative analysis of Vitamin A in four different types of vitamin tablets without any chromatographic purification or saponification. The experiment was performed analysing the H-15 resonance, which appears at δ 4.32 for retinol and δ 4.69 for retinol palmitate, well separated from other

Retinol (vitamin A alcohol) is an accepted adjunctive treatment in infections such as measles. There is also indirect evidence from in vitro, animal and human studies that retinol supplementation may be beneficial in severe malaria. There have, however, been no studies that have examined the pharmacokinetics of acute retinol supplementation in severe ...

Retinol and retinyl palmitate in fetal mice liver: sexual dimorphism
Journal of Pediatric Endocrinology and Metabolism, 2014We determined retinoids liver content in male and female mice fetuses to study a possible sex difference during prenatal development, and to ascertain if vitamin A metabolism is similar in both sexes. The study was performed between developmental days E15-E19, and the fetuses were collected from two main groups: control (no manipulation) and vitamin A (

Summary Purified plasma membranes isolated from rat liver exhibited low levels of galactosyltransferase activity toward endogenous glycolipid and glycoprotein acceptors. The addition of retinol (0.005 mM) stimulated the transfer of [ 14 C]galactose from UDP-[ 14 C]galactose to endogenous glycolipid and glycoprotein acceptors of plasma membranes while
