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 immediately recorded at the optimum wavelength for a period of 5 minutes (absorbance readings taken every 30 seconds). Protein concentration of serum sample (mg/ml) Change in absorbance at optimum wavelength per minute Control serum (C) 8 -0.04 Diseased serum (D) 7.8 -0.6 1c. Using the molar absorption coefficient of NADH as 6220 M-1 cm-1, and by application of the Beer-Lambert law, estimate the enzyme activity in the two samples (C and D). Express activity as moles per second. 1d. Estimate the specific activity of the two samples (moles per second per microgram).

Need full case study with results discussion Introduction etc. Dont use guideline answer ok need full accurate case study. Case History A 32 year old male was found unconscious in his flat following a night out with friends. Attempts to resuscitate the male were unsuccessful. The postmortem indicated sudden cardiac death through cardiac dysrhythmia (arrythmia). There was no medical history of previous heart disease. Two opened packets of Jumping Beans were found on a table close to the body. A specimen of cardiac blood was taken and submitted to the toxicology laboratory for analysis along with the two Jumping Beans packets. . Guidance for Preparing the Case Report The coursework assessment for the module is to prepare a case report in the form of a case report scientific paper published in the Journal of Analytical Toxicology. This guidance information has been taken from the Instructions for Authors for the Journal of Analytical Toxicology however please use the…
