Journal Article
Pimpão, R. C., Dew, T., Figueira, M. E., McDougall, G. J., Stewart, D., Ferreira, R. B., Santos, C. N., & Williamson, G. (2014). Urinary metabolite profiling identifies novel colonic metabolites and conjugates of phenolics in healthy volunteers. Molecular Nutrition and Food Research, 58(7), 1414-1425. https://doi.org/10.1002/mnfr.201300822

Scope
The colonic metabolism of dietary flavonoids, phenolic acids and their phenolic metabolites is complex and many metabolites and conjugates have not yet been unambiguously identified in humans.

Methods and results
Urine samples from nine he... Read More about Urinary metabolite profiling identifies novel colonic metabolites and conjugates of phenolics in healthy volunteers.

Berry fruits are a good source of phenolic compounds and thus, potentially beneficial to health. Phenolic compounds are mainly present as a variety of conjugated forms, either with sugars via O-glycosidic bonds or with other polyols as esters. This c...

Green tea catechins (GTC) reduce UV radiation (UVR)-induced inflammation in experimental models, but human studies are scarce and their cutaneous bioavailability and mechanism of photoprotection are unknown. We aimed to examine oral GTC cutaneous upt...

There is a considerable need to rationalize the membrane permeability and mechanism of transport for potential nutraceuticals. The aim of this investigation was to develop a theoretical permeability equation, based on a reported descriptive absorptio...

Induction of abiotic stress in tomato plants has been proposed as a mechanism for improving the nutritional quality of fruits. However, the occurrence of biotic stress can interfere with normal abiotic stress responses. In this study, the combined ef...
