Abstract:Vitamin K is an essential lipophilic vitamin that acts as a coenzyme in several metabolic pathways. Accurate measurement of apolar metabolites transported by lipoproteins in serum matrices requires high-recovery extractions of vitamin K and its derivatives following standardized protocols. Conventionally developed methods in this field have predominantly employed solid-phase extraction for the measurement of vitamin K and its derivatives. In this study, our objective was to develop an enzyme-assisted extractio… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
