Concept explainers

UV Visible Spectroscopy

Spectroscopy refers to the absorption or emission of light or other radiations by matter. When a substance or chemical absorbs light or radiation, they reach an excited state followed by de-excitation or emission of the light or radiation forming distinct spectra. UV-visible spectroscopy or ultraviolet-visible refers to the absorption and emission in the ultraviolet and visible regions of the electromagnetic spectrum.

The measurement of LDH in the serum can be used to diagnose whether tissue damage hasoccurred.Students were tasked with the development of an assay for LDH activity in human serum samplesfrom a control patient (healthy) and a patient who had suffered cardiac damage. Two samples wereprovided, labelled C and D (Control and Diseased serum).The students decided to follow the loss of absorbance of NADH in an appropriate assay buffercontaining pyruvate as the substrate. Q1 (a) By examining the absorbance spectra(in the image attached) of both NAD+ and NADH below, comment why this approach is suitable strategy. Q1 (b). What would be the optimum wavelength at which they should measure absorbance? Give a reason for your answer. The students conducted the assay for LDH activity using the two serum samples. Each cuvette (path length 1 cm) contained 3ml of a suitable assay buffer (including pyruvate as substrate). 20 microlitres of either serum was added to the cuvette and the absorbance values…
