The pharmacology of polyphenol metabolites on beta-cell function is largely undetermined. We sought to identify polyphenol metabolites that enhance the insulin-secreting function of beta-cells and to explore the underlying mechanisms. INS-1 beta-cells and rat isolated islets of Langerhans or perfused
Catechol O-methyltransferase (COMT) is widely distributed in nature and installs a methyl group onto one of the vicinal hydroxyl groups of a catechol derivative. Enzymes belonging to this family require two cofactors for methyl transfer: S-adenosyl-l-methionine as a methyl donor
Apples, an important contributor to total dietary phenolic intake, are associated with cardiovascular health benefits. Determining the phenolic composition of apples, their individual variation across varieties, and the phenolic compounds present in plasma after apple consumption is integral to understanding
