Apo-14´-Carotenoic Acid Is a Novel Endogenous and Bioactive Apo-Carotenoid [PDF]
Nutrients, 2019 Carotenoids can be metabolized to various apo-carotenoids and retinoids. Apo-15´-carotenoic acid (retinoic acid, RA) is a potent activator of the retinoic acid receptor (RAR) in its all-trans- (ATRA) and 9-cis- (9CRA) forms. In this study we show firstly, that apo-14´-carotenoic acid (A14CA), besides retinoic acids, is present endogenously and with ...

EXTRAÇÃO DE ?-CAROTENO DA MACAÚBA
The Journal of Engineering and Exact Sciences, 2017 O ?-caroteno é um carotenoide que faz parte do grupo das vitaminas lipossolúveis. É essencial para o ser humano e é encontrado nos alimentos de origem vegetal como pró-vitaminas A. É um carotenoide que apresenta ação antioxidante devido às suas ligações duplas conjugadas, que são suscetíveis à oxidação sob ação de luz ou oxigênio. A macaúba é uma fruta

Ultrafast solvation dynamics of 12′-apo-β-carotenoic-12′-acid in [C6mim]+[Tf2N]− [PDF]
Chemical Physics, 2010 Abstract Intra- and intermolecular relaxation pathways of 12′-apo- β -carotenoic-12′-acid, an apocarotenoid with terminal carbonyl substitution, were identified after photoexcitation using ultrafast pump-supercontinuum probe spectroscopy in the 350–750 nm range.

Impact of photocatalysis on carotenoic acid dye-sensitized solar cells
Hybrid Materials, 2015 AbstractSensitized mesoporous titania is of increasing interest for catalysis and photovoltaic devices such as dye-sensitized solar cells (DSCs). For photovoltaic applications, the catalytic properties of TiO2 can cause degradation of the dyes during device fabrication. This is especially the case if natural sensitizers are used.

Electrical Properties of Langmuir Films of Fatty Acid Salts and Carotenoic Acid [PDF]
Bulletin of the Chemical Society of Japan, 1978 Abstract Electric conductivities have been studied for Langmuir molecular layers of barium salt of fatty acids and for the layers of barium arachidate mixed with all-trans-β-apo-8′-carotenoic acid. These results have been interpreted based on an electron tunneling model taking account of the mirror image force.

Cancer Chemoprevention by Carotenoids [PDF]
Molecules, 2012 Carotenoids are natural fat-soluble pigments that provide bright coloration to plants and animals. Dietary intake of carotenoids is inversely associated with the risk of a variety of cancers in different tissues. Preclinical studies have shown that some carotenoids have potent antitumor effects both in vitro and in vivo, suggesting potential preventive

Estabilidade do β-caroteno em massas alimentícias vitaminadas
Revista do Instituto Adolfo Lutz, 1979 B3-caroteno é utilizado em alimentos como corante e pró-vitamina A. A fim de verificar a influência dos processos usuais de cozimento no teor do B-caroteno, foram analisadas, pelo método espectrofotométrico, 100 amostras de massas alimentícias vitaminadas, sendo 50 de sêmola e 50 de massas com ovos.

Análise de trilha para carotenoides em milho
Revista Ceres, 2012 Ainda que sejam considerados os aspectos de magnitude e significância, o estudo de correlações entre caracteres por si só não garante causa e efeito entre eles.
