A sensitive method for the determination of vitamin \(\mathrm{K}_{3}\) using cathodic stripping voltammetry is presented. Using sodium sulfate as the supporting electrolyte at \(\mathrm{pH} 1.70-1.85\), a reductive peak ( \(-0.64 \mathrm{~V}\) vs SCE) is observed. The detection limit is \(1 \times 1
Vitamin K is reduced to vitamin KH2 by lipoate in biological systems. To provide a model system for this reaction, we have studied the in vitro reduction of vitamin K bv 1,3-propanedithiol. This reaction occurs rapidly in dimethyl sulfoxide (DMSO) at 23% demonstrating the validity of this model syst
