Identification of pro-vitamin A carotenoid-rich cultivars of breadfruit (Artocarpus, Moraceae)

Journal of Food Composition and Analysis, 2013
Abstract Breadfruit (Artocarpus altilis) is an underutilized staple crop that may be a good source of pro-vitamin A carotenoids (pVACs). The current study assessed the total carotenoid contents and carotenoid profiles of 94 cultivars of breadfruit and three related species to identify pVAC-rich germplasm and determine if total carotenoid content ...

Regulation von Immunsystem und Allergien. Retinoide, Vitamin A und Pro‐Vitamin‐A‐Carotinoide

Pharmazie in unserer Zeit, 2009
AbstractVitamin A und Pro‐Vitamin‐A‐Carotinoide sind in hohen Konzentrationen in der westlichen Ernährung enthalten. Eine humane Vitamin‐A‐Defizienz kommt in westlichen Ländern daher extrem selten vor. Eine Überversorgung mit Vitamin A tritt jedoch häufig auf und kann möglicherweise ein wesentlicher Faktor bei der gesteigerten Prävalenz von atopischen ...

Concentration of pro-vitamin A carotenoids in common beef cattle feedstuffs.

Journal of animal science, 2012
Quantification of the pro-vitamin A carotenoids in feedstuffs commonly fed to livestock has been ignored for many years. A greater dietary concentration of vitamin A has the potential to limit adipogenesis in cattle, thereby reducing carcass quality and value.

Quinones as reagents for the dehydrogenation of cholesteryl acetate to pro‐vitamin D

Recueil des Travaux Chimiques des Pays-Bas, 1940
Abstract1,4‐Quinones, when heated with cholesteryl acetate in sealed tubes at 120 to 135° for 6 to 8 hours, were found to partially dehydrogenate the sterol ester to a pro‐vitamin D (probably 7‐dehydro‐cholesteryl acetate). The crude products, after the removal of hydroquinones, quinhydrones and unreacted quinones, were irradiated for 4 hours with ...

α-Tocopheryl succinate epitomizes a compound with a shift in biological activity due to pro-vitamin-to-vitamin conversion

Biochemical and Biophysical Research Communications, 2002
With the advent of the third millennium, a number of pathologies have been eradicated or taken under control. However, the incidences, of cancer and atherosclerosis, the two most common causes of death in developed countries, have increased or, in some instances, only stagnated.

Chapter 18. Thin-layer Chromatographic Analysis of Pro-vitamin A Carotenoids

2012
The name pro-vitamin A carotenoids is derived from the fact that they produce one or two molecules of vitamin A upon hydrolysis, oxidation or digestion in the body. Vitamin A is present in our daily diet in the form of retinyl ester, retinol, retinal, 3-dehydroretinol, and retinoic acid.
