Retinol palmitate against toxicogenic damages of antineoplastic drugs on normal and tumor cells
Chemico-Biological Interactions, 2020The lack of tissue selectivity of anticancer drugs generates intense collateral and adverse effects of cancer patients, making the incorporation of vitamins or micronutrients into the diet of individuals to reduce side or adverse effects of antineoplastics.

Retinyl esters are the storage form of vitamin A in skin, and retinyl palmitate (RP) accounts for the majority of the retinyl esters endogenously formed in skin. RP is also obtained exogenously through the topical application of cosmetic and skin care products that contain RP.

Emulsion and Vesicle Formation of Retinol and Retinyl Palmitate with Egg Yolk Phosphatidylcholine
Journal of Colloid and Interface Science, 1995Abstract Spreading pressure measurements showed that retinyl palmitate (retinol palmitate, ReO-Pal) and egg yolk phosphatidylcholine (PC) were practically immiscible and separated into PC bilayers and ReO-Pal liquid. On the contrary, substantial amounts of retinol (ReOH) were incorporated into PC bilayers.

Levels of retinyl palmitate and retinol in stratum corneum, epidermis and dermis of SKH-1 mice
Toxicology and Industrial Health, 2006Vitamin A (retinol) regulates many biological functions, including epidermal cell growth. Retinyl palmitate (RP) is the major esterified form of retinol and the predominant component of retinoids in the skin; however, how endogenous levels of RP and retinol in the skin are affected by the age of the animal remains unknown.

A 67-year-old woman with acute promyelocytic leukemia (APL) showed a marked decrease in leukemic promyelocytes with concomitant maturation of leukemic cells during treatment with retinol palmitate. A culture study in vitro revealed that retinol, which is the main metabolite of retinol palmitate detected in plasma, induced morphological and functional ...

Determination of retinol, retinyl palmitate, and retinoic acid in consumer cosmetic products
International Journal of Cosmetic Science, 2010J. Cosmet. Sci., 60, 485–500 (September/October 2009)SynopsisRetinol and retinyl palmitate are frequently used in cosmetic products. A simple, rapid, and sensitive reversed‐phase high‐performance liquid chromatography (HPLC) method with ultraviolet (UV) detection was developed for the quantitation of retinol, retinyl palmitate, and retinoic

1. The purpose of this study was to assess the incorporation of retinol into quail egg yolk and cholesterol concentration in response to supplementation with different quantities of retinyl palmitate (600, 1200, 2400 and 4800 microg). 2. Supplementations were performed weekly for 4 weeks and the yolk retinol was measured using high performance liquid ...

Effect of retinol palmitate on ovulation rate and embryo quality in superovulated cattle
Theriogenology, 1995Abstract We evaluated the influence of administration of retinol palmitate (Vitamin A) on ovulation rate and embryo quality in 48 beef cows superovulated with 2 different doses of FSH. Synchronization of estrus was accomplished by giving 2 injections of prostaglandin F 2α (PGF) 11 d apart.

2: Final Report on the Safety Assessment of Retinyl Palmitate and Retinol
Journal of the American College of Toxicology, 1987Retinol is the naturally occurring form of vitamin A; Retinyl Palmitate is the ester of Retinol and Palmitic Acid. In acute oral studies, Retinol was slightly toxic to mice, and Retinyl Palmitate was practically nontoxic in mice and rats. Large single doses can be lethal. It is recognized that Retinol is essential for reproduction; however, high intake
