Photopotential of Chlorophyll a Containing Lecithin BLM Formed with and without Carotene
نویسنده
چکیده
The potential of lecithin BLM with chlorophyll a and with and without carotene has been measured. The BLM containing both chlorophyll a and carotene have shown the highest value of the photopotential. Stronger fatigue effect during light puis excitation has been found on BLM with pigments than with isolated chlorophyll a-protein complex extracted from blue green alga.

Effect of ß-Carotene on Delayed Light Emission from Aggregated Chlorophyll
Delayed light emission (DLE) from aggregated chlorophyll is used to probe energy transfer between aggre gated chlorophyll and ß-carotene. Preilluminated ßcarotene when injected into a dark chamber containing aggregated chlorophyll, induces DLE from aggregated chlorophyll. If the dark chamber contains only monomeric chlorophyll, there is no DLE. The intensity of DLE is de pendent on the time o...
متن کاملStatistical Optimization of The Four Key Factors on β-Carotene Production by Dunaliella salina Under Laboratory Conditions Using Response Surface Methodology
During recent years, there was growing demand in using microalga valuable products such as β-carotene in health care. β-Carotene has anti-cancer and anti-aging properties for human. In Dunaliella salina cells, β-carotene has a major protecting role for biomolecules, when the production of reactive oxygen species elevated. In the present study, we investigated the influence of the four most effe...

متن کاملSelective factors governing in vitro β-carotene bioaccessibility: negative influence of low filtration cutoffs and alterations by emulsifiers and food matrices.
Because of their putative health benefits, the biological fate of carotenoids after digestion has been met with much interest, and ex vivo methods using carotenoid standards to study their digestion and further metabolism have been developed. In the absence of a complex food matrix, that is, when studying isolated carotenoids, protocol conditions of gastrointestinal digestion models have to be ...
