Absorbance measured at 280 nm (A(280)) is used to calculate protein concentration by comparison with a standard curve or publishedA kinetic-spectrophotometric method for the,A kinetic-spectrophotometric method is proposed to determine glucose in solutions. Measurements were performed at 400 nm; the negative peak was obtained by subtracting the absorption spectra of myoglobin (Mb) before and after oxidation. In this method, glucose is added to a mixture of Mb and glucose oxidase. Glucose is oxidized by glucose oxidase and oxygen to gluconate and hydrogen
