A New Synthesis
We are on the eve of a revolution in health policy that will forever change our way of thinking about health and healthcare. A few years from now, our vision of the organization and the administration of healthcare services will be transformed. This is not a revolution born out of crisis, albeit the financial pressure on public and private funders of healthcare is clearly at play. It has not ...
متن کاملSynthesis of carotenoid-cysteine conjugates.
Isozeaxanthin under acidic conditions forms an allylic cation which reacts readily with thiol nucleophiles. With N-acetylcysteine as a nucleophile the products obtained are carotenoid-cysteine conjugates in which the amino acid moiety is attached to the carotenoid via sulphur in position 4. The water solubility of the products can be increased by deprotection of the amino group. The antioxidant...
متن کاملSome studies on carotenoid synthesis.
INTRODUCTION Traditionally synthesis is invoked as the final proof of a structure deduced by other means. In the carotenoid field synthesis is being used increasingly as an integral part of structural studies in order to elucidate some molecular feature for which the other evidence is inconclusive or ambiguous. Synthesis also fulfils the very important role of making many carotenoids much more ...
متن کاملInheritance of Carotenoid Differences I N the Tomato Hybrid Yellow
ELLOW varieties of tomatoes have been known since the crop was first Y in t roduced into Europe shortly after the discovery of America, and were probably to be found in Mexico before the conquest (JENKINS 1949). HALSTED et al. (1905) reported on the red x yellow hybrid, establishing the fact that the color difference was due to segregation at a single locus, a conclusion that has been confirmed...
متن کاملSynthesis: a new project for the Journal of Applied Physiology.
AT ITS RECENT MEETING, the Associate Editors of the Journal of Applied Physiology discussed the role of publishing scientific reviews in the journal. Policy had been that the only reviews we would publish were what we call “mini-reviews” written on focused subtopics of a Highlighted Topic. These were, of course, by invitation only. Thus larger stand-alone reviews on individual topics submitted ...
