All-enzymatic HPLC method for determination of individual and total contents of vitamin B6 in foods
BACKGROUND There is a need for a reliable and accurate method for quantification of each of the seven individual vitamin B(6) compounds including pyridoxine-β-glucoside in foods. OBJECTIVE To determine pyridoxal (PL), pyridoxamine (PM), pyridoxine (PN), pyridoxal 5'-phosphate (PLP), pyridoxamine 5'-phosphate (PMP), pyridoxine 5'-phosphate (PNP), and pyridoxine-β-glucoside (PNG) in foods. DE...
متن کاملNew Enzymatic Colorimetric Method for the Quantitative Determination of Phenylalanine in Dry-Blood Spots
Phenylketonuria (PKU) is an autosomal recessive disorder, which is characterized by severe mental retardation, microcephaly and seizures. The symptoms of this disease can be prevented if detected soon after birth. Therefore, blood Phenylalanine (Phe) measurement is essential for the early diagnosis, treatment and dietary monitoring of PKU patients. The goal of this research was to introduce a r...

15 صفحه اولEnzymatic method for determination of CO2 in serum.
We describe an enzymatic method, requiring only 10 mul of serum, for determining CO2 as bicarbonate or dissolved gas. Phosphoenolpyruvate carboxylase catalyzes the reaction of HCO3- with phosphoenolypyruvate to give oxalacetate. The resulting NADH, in the presence of malate dehydrogenase, is oxidized to NAD+, and the decrease in absorbance at 340 nm is directly proportional to the amount of CO2...
متن کاملAn enzymatic method for glucose determination in body fluids.
ENZYMATIC REACTIONS, BECAUSE of their great specificity, are among the most valuable analytic tools at the disposal of the chemist. The method for glucose here described represents an adaptation of such biologic reagents and is a distinct departure from sugar methods now in common use. It is based upon a unique principle communicated to us by Keston (1) prior to publication (2). Traditional met...
