A round robin comparison was performed in order to test the performance of a recently developed LC-MS/MS method for quantification of 6 folate forms. Eighty-nine samples representing the food groups of fruits, vegetables, legumes, cereals, dairy products, meat, and offal were analyzed by two
Cytochromes P450 from plants have the potential to be valuable catalysts for industrial hydroxylation reactions, but their application is hindered by poor solubility, the lack of suitable expression systems and the requirement of P450s for auxiliary redox-transport proteins for the delivery of
